Gulfs of Meaning

In a world where borders don’t often correspond landmarks or terrain, tensions of incursions on new forms of territoriality multiply. Tensions of violations of airspace and national waters pose questions of the accuracy reliance on mapping systems, moreover, difficult to contest or resolve on a single map, as, at the same time, the frictionless nature of drone flights–here embodied by the costly RQ-4A Global Hawk, whose price as a high-end unmanned surveillance tool reflects its abilities to transgress borders without detection, flying at over 20,000 feet across borders at a speed of five hundred miles per hour, embodies an ability to remap a space of surveillance by superior mapping technologies than other countries. With literally hours remaining before devastating military airstrikes on Iran, amidst fears that a slight miscalculation or misinterpretation of mapping systems could precipitate an unwanted war of massive scale, the strikes were canceled at 7:30 p.m. Washington time, and the threat that Iran had “made a very big mistake” de-escalated. Trump surprised the world by suddenly allowing for the margin of human error, even as he insisted the drone was flying “clearly over international waters,” rather than Iranian airspace just 750 miles southeast of Tehran, refusing to relinquish his own map of wherejn the Global Hawk was downed.

The trust in this unmanned drone may possess its own almost hubristic quality. For its downing by Iranian missiles downed not only a costly military surveillance tool, but punctured a space of surveillance of the Persian Gulf and Iranian territory, and a sense of security in a precarious geopolitical region–at the same time as the American government seems to be bent on increasing tensions about the continued flow of crude petrochemicals to much of the industrialized world, creating global flows and energy markets that are themselves concealed by the question of at what point Iranian missiles struck the drone–or into whose national airspace the drone was flying.

The downing of the drone punctured confidence in a continuous space of surveillance that was built, painstakingly and over time, to guard those global energy markets. While the shock to U.S. military intelligence may have been that Iran had gained the ability to observe, fire at and down the high-flying unmanned vehicles that they had purchased at considerable expense from Northrup Grumman, not revealed even by the most precise hexadecimal GPS coordinates, which would render the costly drones more than a poor investment in preparation for the very grounds of war that Northrup Grumman had promoted to transmit high-resolution images from higher than ever altitudes of sensitive hotspots in “real time.” The United States Military didn’t ever think Revolutionary Guards possessed or could acquire marked not only a threats of war,–and chose to celebrate the RQ-$ “Global Hawk” as a tool of maintaining an infrastructure of global surveillance rooted in Afghanistan, Iraq, and Syria, as well as covering the Persian Gulf, while piloted remotely, by yet another one of the increasing paradoxes of the globalism of globalization, by pilots in bases in Beal, California and Grand Forks, North Dakota, far from the military theaters they sought to control

But the shattering of this imagined space of global dominance occurred not in U.S. bases, or even on the military maps of Americans, but rather on the screens that Iranians used to monitor the unmanned vehicle’s flight, and, by extension, the missiles they launched that downed it. The missiles’ surprising accuracy disrupted the imagined continuity by which the United States hoped to extend sovereignty into international waters to protect traffic across the Strait of Hormuz–not only by a new surface-to-air missile, but a new radar system able to detect the drone–

–that effectively ended a map of surveillance that will no longer exist in the face of new Iranian defense systems allowing Revolutionary Guards to protect their territorial claims.

The Persian Gulf region has long been planned and imagined to be a new theater of possible war. Indeed, each side has become compelled to map the potential battle field in ways that has been forced the region to be remapped, creating a delicate balance of often contesting Exclusive Economic Zones, international waters, and territorial waters, in ways that have constrained the possibility of American surveillance. But the drone’s downing air revealed that Iranian guidance systems of surface-to-air missiles that Iran possesses to target drones, aircraft and unmanned vehicles are no longer clearly understood by the U.S. Army or U.S. military intelligence. The American “upper hand” in mapping technologies has perhaps been punctured, in ways that may cause the entire battlefield to need to be remapped in costly ways, if to preserve the delicate balance global trade of petroleum from the Persian Gulf, one of the most concentrated and easily accessible site of petroleum reservers, especially in the increased tensions between the United States and Iran.

Airspace and territorial waters are more difficult to map on earlier maps, and difficult to map on top of shorelines, or in navigational routes, perhaps, for an untrained eye, but the proliferation of alternate readings of sovereign space have become especially fraught in the waters of the Strait of Hormuz, where overcrowded traffic turns on hairpin turns, seems to have been detected entering Iranian airspace–if one trusts the maps tweeted out in self-defense by Iran’s Foreign Minister Javad Zarif–who argued the unmanned surveillance drone had crossed the “red line” of its sovereign airspace without warning, ignoring alerts from Revolutionary Guards, and interpreted as threats to its sovereignty.

Coming on the heels of Iranian threats to shut the Strait of Hormuz to all traffic, as Iranian speedboats patrolled the waters, as if tempting to assert their control over the narrow passage-way out of belief that “if our oil does not go through the Strait, other countries’ will certainly not cross the Strait,” the jockeying for power over the transit of oil in international waters set up a conflict between where national sovereign interests began and ended, and what power the United States regained on a global geopolitical stage, even as the United States openly asserted the upper hand of global surveillance over what is one of the narrowest maritime site of petroleum transit in the world wildly out of proportion to the millions of barrels that cross the narrow strait daily, a transit that wildly dwarfs the petroleum carried to global markets by other maritime routes–despite the quite narrow nature of its passage, and the even narrower space of international waters by which oil tankers navigate the Strait.

Where the unmanned vehicle flying American colors flew–and whether it crossed into a sovereign space–bedcame a flash-point of regional tensions, so much that the downing of the $110M drone, long celebrated by the U.S. Army as covering surveillance needs over the Gulf, embarrassingly became a target of Iranian defenses, as it was downed on June 20, even as it was flying at over 60,000 feet, or above what American forces believed that Iranian Revolutionary Guards could detect. The illusion that American unmanned surveillance drone RQ-4A Global Hawk could itself move frictionlessly across national boundaries without being downed was itself unmanned, creating a small catastrophe or large disruption in the international balance of powers.

Did it cross the red line?

Or, as the U.S. Military’s Central Command tried to assert with its own parallel graphic of where the drone was downed, showed the apparent intensity with which Iran was able to pursue the dominance in a theater of oil transport vital to the global energy economy, and to the global economy that was attached to it, signaling a real Achilles heel in the continued image of American global invulnerability. which the United zStastes was determined to map as occurring outside Iranian sovereignty as an attack on American property and super-costly military hardware–starting a war of maps on the heels of a renewal to past Tanker Wars, both possibly poised to escalate into actual military bombardment.

It certainly seemed that the downed Global Hawk would constitute something akin to the arrow fired by the Trojan Pandarus into the groin of the Spartan Menelaus, the great warrior and husband of Helen of Troy, causing blood two streak down his legs, in an image of the fraught virility of the fabled warrior to incite the wrath of the leader Agamemnon, if not reveal newfound imbalance of military relations which Athena seemed to use to provoke the shattering military disaster of the Trojan War by starting the siege of Ilium. Would the downing of the jet provide the occasion of the bombing of Iran that Donald J. Trump has hoped to begin, matching his heightened bellicose rhetoric with the presence of a violent escalation of arms?

What happened was not clear, as was evident in the difficulty of mapping the event. When the costly U.S. Army Global Hawk drone looped back in the course of its surveillance of the Strait’s coasts, possibly entering Iranian airspace, after it was shot down, reverberations spread across the world, quite quickly. President Trump declared that Iran had shown itself by this act to be “ready for war” before plans for a miltirary reprisal were called off with but hours before it was poised to begin–perhaps saving the world from a global catastrophe, although U.S. Secretary of State was later dispatched to forge an improvised alliance against Iran in the coming weeks. Although war was averted on a global scale, the question of whose map was more authoritative, and whose could be trusted, reveals much about the contested status of authoritative maps in the globalized world, beyond being a debate waged across social media. The debate turned on different ways of reading space–or of wanting to read space; one hinged upon a notion of national boundaries and sovereign space, whereas the other relied upon the frictionless space of a notion of regional surveillance.

The downing of the drone lifted a corner on the shifting tensions in globalization, and indeed the increased problems of lamination of multiple maps over the increased density of economic traffic across the Strait of Hormuz, and indeed the conflicts between national and international waters along which petrochemical and crude petroleum leaves the increasingly blurry–if much mapped and over-patrolled–region of the Persian Gulf. The tensions were not about the drone. At least not only. The ratcheting up of tensions with a policy of “maximum prsssure” and rhetorical escalation has ratcheted up tensions, as Iran policy has been transformed into a flag-waving exercise of defense against a perceived infidel enemy–one that has disdained civil discourse and alleged overtures of open negotiation–in ways that are about American desires to map “international waters” and international airspace–

–rather than recognize even the potential legitimacy of a sovereign state’s defence. For all the mapping of “national” spaces on new maps of the region–that for all their identification of names of nations affirm the abilities and potentials of U.S. surveillance maps.

The Strait of Hormuz exists on the borders of several nations, and might be mapped in multiple ways. While the central waters of the Strait–which narrows to just twenty-one nautical miles, or less than forty kilometers–nonetheless retains a thin band designated as international waters, which puts it outside of local sovereignty. But the Strait increasingly is mapped in radically different global and local contexts, making the question of its territoriality and international status a question of increased tensions in the past weeks–when one American Global Hawk, a pretty fancy piece of surveillance, was downed. The cost was not only limited to the fourteen million dollar piece of military hardware, or to its symbolic loss, but the casualty of a sense of security in the frictionless policing of an economically vital transit routes–and the hegemony of mapping and ensuring the safety of the movement of crude oil from the Persian Gulf to global energy markets.

What appears to be a navigational course, in an era when territoriality is designed by points, rather than either landscapes or terrain, created an increasingly serious a quandary for measuring locations along a nautical map alone, or in reference to a mainland. For the question of incursion in territoriality–as the high-grade U.S. Army drone that was shot down in Iranian airspace–is not so evident from the Gulf waters, or the landscape over which it flew, approaching the Islamic Republic of Iran’s sovereign region of Hormogazan Province, or appearing to stray outside of the path of international airspace, or at least doing so at a height of 20,000 meters, higher than Americans’ expected Iranian radar systems could detect, but in fact just within the Iranian Revolutionary Guard’s radar detection abilities.

Was it an incursion of sovereignty? It depends less on whose maps you are looking at, than what sort of landscape of military conflict and geospatial intelligence you followed, or what side of the cat and mouse game of mapping the nature of the international status of the navigational paths of the Strait you follow to understand how securing “free passage” through he Strait of Hormuz became rooted in the security of abilities of mapping energy transit. If the Strait has emerged as a hotspot in an increasingly irrevocably globalized world, the conflict between Iran and American interests arose as abilities of local mapping temporarily shifted, and the hegemony of American mapping of gulf waters was challenged, as Iran accused the United States of crossing a long drawn “red line” of sovereignty in spying on the banks of a Strait that Iran has increasingly asserted its ability to close, and indeed to monitor the escalating American surveillance of its waters and shores.

NORAD Maps the Flight of Santa’s Sleigh

If Santa Claus is global, the image of Santa living in the North Pole outside of sovereign divides has been elevated to a new horizon of expectations in the age of real-time maps. The question of “Where is Santa?” now can be responded to on a real-time viewer, prepared each and every Christmas Eve for over fifty-fie years, the North American Aerospace Command. For since the Cold War, and through the present age of smart phones and real-time tracking, NORADh as invited viewers all over the world the chance to track the gift-laden sleigh of Santa crossing the night-time sky at the speed of starlight. Never mind the different hours and expectations of Santa Claus in different nations or countries. For NORAD allows the world to track the flight of Claus cum reindeers on NORAD’s Santa Tracker, an annual collective exercise in mapping of increasing popularity, moving the image of bearing gifts into the globalized world.

images-52.jpeg

Indeed, the mind-boggling proportions of its popularity, attracting upwards of 20 million individual users in 2011 alone, is a statement not only to its improved UX, but to the versatility of its incorporation of mapping servers better to imagine the itinerary of Santa’s airborne sleigh.  For while we once envisioned the night-time flight of Santa Claus far-off and against a starlit sky and full moon, to accentuate the surprise of a magical sled-borne itinerary–

–the Santa Map brings that journey up-close for everyone before a computer monitor, following a sort of sleigh space that is the surrogate for airspace.  The remapping of Santa’s itinerary has been done in a way that tracked, as the sleigh’s global progress is intercepted and relayed online in real time from posts of remote observation to viewers around the world.  And in an age of global surveillance, there seems to be no reason why Santa’s sleigh cannot as well be surveilled for the interests of children everywhere.

There’s a huge appeal in the ways that the Santa Map creates and imagined community, as much as it embodies an annual itinerary.  The interest in tracking Santa’s sleigh has grown considerably in recent Christmas Eves.  The huge interest in tracking Santa’s sleigh–and effectively mapping the visits of the airborne sleigh into our hearth–is a way of bringing maps in line with pleasure at a time when we need to look for solace where we can find it, and where we can find a comfort that the onslaught of most maps of contemporary events in fact rarely provide.  

Christmas has been a communal but solitary experience–located in the hearth and around the tree, and gift-opening a ritual of individual families–but somewhat serendipitously, the collective witnessing of the Santa Map offers a vicariously removed experience for crowds of viewers, removed from one another but creating the illusion of comprehensively witnessing the arrival of a fictional character to homes everywhere, as if to knit us together in holiday wonder, suspended for the evening in an imaginary international airspace of momentary world peace.  In recent years, but perhaps since the Cold War, this particular image of good cheer provides the odd inversion of the danger of the military missile strikes, if not offering the miracle of suspending fears of missile strikes, or the contradictions implicit in imagining peace in a world that lies on the brink of global war by using the very tools to chart missile defense systems as instruments of good cheer. Santa may face a different workweek in the malls where he can now be met in many different nations–as he traverses national borders with different work weeks!–

Santa’s Workweek in Ottawa Mall

–but the folks in the U.S. government and NORAD it completely reasonable to have the right to track the geospatial complexity of Santa’s sleigh ride, without removing any mystery out of Christmas holidays. It may be even reassuring that if Christmas Eve is Santa’s busiest hour of flight, the arcs of where reindeers guide his flightpath can be illuminated on our devices, in vivid geospatial specificity and even local detail.

Gravity’s Landscapes: Bombed Out Landscapes over Time

When the Germain army declared, in April of 1942, as accelerating violence of global war brought the arrival of the British bombing of German towns, the wartime Nazi government boasted that they would use native maps in the public domain to destroy valued buildings in England with impunity. over 20,000 bombs fell on the city of London, destroying beyond repair 116,000 buildings, they left a bombed out landscape that has been forgotten with time, but increasingly offers an eery reflection of the twenty-first century’s bombed out landscapes created by saturation bombing raids that the precision strikes of GPS-enabled missiles allows. The bomb sites persisted long after World War II ended, scarring the urban landscape as it was dramatically overbuilt in n unheard of density unforeseen in wartime years, so that it has increasingly faded from our collective memory, even as we try to prevent the bombed out landscapes of recent memory becoming a terrifyingly blur.

In blood-curdling claims that prefigure the American threat to violate international law by targeting of historical sights in Iran, the bombardment of Syrian cities by Iranian supplied forces, the bombing of cities in Ukraine, or the Israeli bombardment of Gaza by precision strikes, the V-2 bombing of London began from the declarative Teutonic bast of a boast,’We shall go out and bomb every building in Britain marked with three stars in the Baedeker Guide.” The conversion of a tourist map to a map of targets may suggest slippage between German fetishization of precision in tourist maps tied to cultural formation to a German Luftwaffe’s determination for an arial blitzkrieg determined to destroy historical sites. The precise strikes of flattening a landscape by V-1 bombs and V-2 rockets blanketed England with a “Vergeltungswaffe” of vengeance weapons, an air-launched arsenal designed to destroy whatever had once been celebrated on the map, with a destruction that was poorly processed in literary terms as it was hardly able to be understood.

A screaming comes across the sky . . . it has happened before, but there is nothing to compare it to now.” There was no precedent for the destruction of the London Blitz, and the experience of a bombed out landscape was hard to distance oneself from–and all but impossible to map. If Thomas Pynchon invited us to imagine the progressive targeting of the city–writing in a time when many bombed out areas of London were still fenced off, some still not benefitting from the Lend Lease act of government financing, and some still present in the 1970s, when I visited the city as a child, the bombed out landscape is impossible to imagine in real time, perhaps, as the front lines of war blurred with the home front. During the blitz, Graham Greene gave it his Eton best, chiding Anthony Powell how the bombing raids made London “extraordinarily pleasant these days with all the new spaces” as rocket bombs had torn through buildings: Greene distanced himself from violence by affecting admiration for the “rather Mexican effect of ruined churches.” He was not only being picturesque, but looking back on the hatred he felt for the Mexican landscape whose ruins he had officially visited in 1937-8, while investigating Socialist outlawing of Catholicism in Mexico; the dark sarcasm no doubt concealed fears rockets rendered the capitol akin to the landscape he saw as a periphery whose poverty and dishonesty he loathed as “a state of mind” without morals, economic precarity, bad food and drink, and bad faith.

The bombing of London followed the escalation of raids launched on Germany from seven airfields built for the purpose in East Anglia, after 1940, which had dropped seven hundred and thirty-two thousand tons of bombs on German cities by the new strategy of “carpet bombing,” creating firestorms in German cities from Cologne to Bremen, from Würzburg to Stuttgart, and many more, creating landscapes of instant ruins in a form of psychological warfare that seems to effective to be almost omitted from German postwar literature. Whatever churches Greene saw in Tabasco and Chiapas were empty of ritual or priests by state decree, secret Masses confined to private houses by priests who register with civil authorities after agrarian and land reforms stripped the church of property. If Mexico seemed a periphery, London seemed in danger of becoming one, as Britain’s bombardment by Germans hoped to reduce England’s capitol to ruins; he disdained American superiority to Mexico whose wealth they had extracted, and thought little of the “cold, snarky chambers” of Mexican ruins in the seventh century Mayan city of Palenque, but the bombing of London by “vengeance weapons” threatened rapidly to reduce the metropole by a Third Reich that hoped to triumph over Britain by consigning it to the past to bring to a close an early historical epoch.

If Mexico was “a country to die in and leave ruins behind,” the specter of silent, majestic ruins may have been hard to map onto London, but the Bomb Damage map undertaken by surveying the buildings damaged and destroyed by German bombs provide a fascinating attempt to maintain equilibrium in a time of devastation. The evocation of a ruins was telling at a time in the almost exactly eight month bombing campaign from October 1940 to early June 1941. V-2 “vengeance weapons”–or simply “revenge weapons”–were unlike earlier types of war, definitively shifting military hostilities to a home front. If Graham Greene had imagined Mexico as the glamour site of the adventures of Pancho Villa in his childhood, the dangerous landscape of wartime suggested , the start of a campaign whose targets were chosen from a travel guide was a metaphor of how bomb strikes might close a historical epoch by sheer application of force, confirming the imperial destiny claimed for the Third Reich, and reduce London to the material traces of a past Germans long studied of Rome’s Empire and ancient Greece.

It must have been quite hard to watch the raids at the stoic remove it demanded, but the British were up to it. The emigre bookseller and intellectual historian Chimen Abramsky tied to wacth at close hand London’s bombing unfold by binoculars from the roof of his Highgate residence, scanning the urban landscape for the sight or sound of bombs’ inevitable before joining fire brigades to rush to the scene to mitigate flare-ups in urban neighborhoods, stunned “London was on fire, burning from four sides,” as if the Nazi invasion of Poland, Belarus and Russia had followed him and his father refuge. The V-2 bombs were perhaps only a rehearsal for the aggressive carpet bombing of the Siege of Stalingrad of late August 1942 they preceded; the utter destruction of those air raids challenged novelist Vasily Grossman’s points of reference–“Everything burned down. Hot walls of buildings, like the bodies of people who have died in the terrible heat and not yet cooled down . . . miraculously standing–amid thousands of vast stone buildings now burnt down or half-destroyed,” he wrote in his notebooks. Stalingrad became a landscape of historical ruins, “like Pompeii, caught by destruction in the fullness of life.”

Is it an an oddly English response to try to map this destruction in poignant pastels, as in the header to this post? The elegant maps of the destruction of buildings that were tallied with care during the Blitz cartographically process the bombs’ arrival in an array of watercolors, as if to hold at distance the violence done to place with which each writer–Greene; Abramsky; Grossman–struggle to frame in a language of ruins that suggest historical breaks. They affirm the continuity of the landscape, rather valiantly, against Ordnance Maps, as if to chart hopes for rebuilding.

They are far leess abstracted than recent dense collection of red datapoints of where bombs hit in the recent webmap “Bombsight” charts, which illustrate the overpowering reach of the rockets but makes it hard to comprehend the scale of their effects by the density of these crowded datapoints on a Google Maps base map–even if one zooms in on closeups on individual neighborhoods against the muted generic landscape of a base map. The unprecedented intensity on London, temporally collapsed, challenges the viewer to process the impact of eight months of rockets in totality. The preservation of a set of hand-painted Bomb Damage Maps created to assess the rockets’ devastation in real time offer keys to navigate that experience, as records of the cartographic reaction to the modern violence they wrecked and the transformed urban landscapes that so many Londoners continued to inhabit.

Bombsight

As the destruction of these cities fades from collective memory, the online sources of like “Bombsight” that aggregate actual geodata placing the density with which all rockets and bombs dropped on the city in individual time frames offer something like a slider bar to view the violence, without the fire and death, remotely on our screens. But how to describe or take stock of the scale of such devastation, let alone to do so in a map, or to make contemporary maps and accounts to be embodied in an adequate spatial form? For the journalist Grossman, bombs that fell amidst the flames of burning houses over Stalingrad redefined the place as it had been known from maps, and redefined the lived space of the city that were unable to take stock of by a single observer. “It was no longer a matter of individual explosions; all space was now filled by a single dense, protracted sound” of the howls of bombs, air cloudy with white dust and smoke, the characters of his novel search for images of Pompeii, wondering if any one will remember them, the thunder of explosions and crack of anti-aircraft guns marking time against the howl of a bomb that grew in volume, altering one’s sense of time as “howling seconds, each composed of hundreds of infinitely long or entirely distinct fractions of seconds,” erased desire, memories, or “anything except the echoes of this blind iron howl.”

Whether referencing the obliteration of space by the Baedecker guides was a conceit of historical migration of empires or conflated cartographical superiority of touristic guides with the precision of aerial bombardment suggests the crossing of categories of bombarding civilian populations. The obliteration of clearly demarcated lines haunted Stalingrad’s bombardment included modern incendiary bombs, for Grossman, as tens of thousands of which small canisters that could tumble out of in containers of thirty-six filled the air with a distinct screeching unlike the whistles of high explosives, a screeching that echoed the screeching of the V-2 bombs that Thomas Pynchon employed as the arresting auditory perception of the mesmerizing opening sentence of Gravity’s Rainbow focusses on the “new sound” then unknown of “A screeching came across the sky” . . . Grossman focussed on the “new sound” bombs made in Stalingrad as unlike the whistle of hunters of high-explosive bombs, but “penetrated every living being [from the] hearts of those about to die [to the] hearts of those who survived–all hearts clenched in tight anguish,” so that “there was no one who did not hear it as they plunged into the city, rendering “building after building joined in a single blaze and whole burning streets fused into a single, living, moving wall . . . as if a new city of fire had appeared over Stalingrad,” introduced by the distinct sounds that follow the arrival of “planes coming from north, west, east and south [that] met over Stalingrad,” whose descent on the scientific “seemed to be the sky itself that was descending–sagging, as if under dark, heavy storm clouds, under the vast weight of metal and explosives.”

To register the new city rendered by daily destruction, lest the earlier city by lost, the London City Council undertook in a valiant act of cartographic preservation during the air attacks from September, 1940, just after the Germans had planned to invade Russia, to 1941, and amplified with the attacks of V-2 rockets by 1944, to ensure a level of destruction more sudden and more terrifying than the incendiary bombing of Stalingrad. The ways that the British Army mapped the destruction that V-2 rockets of terrifying precision were able to carve out of the city of London had been long lost, but the recovery of these map provides an eery echo of the historical models and precedents of civilian targeting of historical sites that haunts the contemporary world. For he scars of ethanol-fueled V-2 rockets that speedily struck wartime London seventy years ago are a good place as any to start to map the systematic bombing of civilian spaces.  As if mapping the liquid-fueled fantasies of destruction of Wernher von Braun, the V-1 and then, subsequently, V-2 bombs silently arrived to create a psychologically searing topography of death that transformed the city, immersing civilians to new topographies of fear.

The contemporary graphic tabulations of damages in recently published Bomb Damage Maps  orient one in chilling ways to the progress and degree of bombing wartime London in purples, violets, oranges, and light blue on London’s familiar plan.  The pastels are disarmingly tranquil if not placid in tenor, but seem to conceal within a Benjamin Moore-like in their variety, which seem to reveal a of destruction wonderfully measured concealment  resistance of a British culture of grim-faced exactitude to the horrific episode of wartime destruction, generations away from the bombardment of images of bombed out landscapes in Beirut, Syria, or so much of the Middle East and Libya today.  If these pencilled sketches seem oddly antiquated and removed, the poignant attempt to come to terms with the radically escalation of destruction in the  devastatingly regular tempo of accelerating bombardment that is known as the London Blitz–even if they cannot capture the panic, commotion, terrified screams or chaos, in the muted pastels in an aerial perspective that affirm the organic city that once existed in a still alive past.  The three weeks of airstrikes on Gaza that have focussed on obliterating a density of buildings and underground tunnels in Gaza City to drive an underground terrorist cells form the region are only the latest of focussed campaigns; can their experience be better understood by guides to process aerial bombing raids in the past?

The images of community that they preserve in a time of the compacting of time and space stand in a bizarre psychological counterpoint to the terror of the Blitz, an attempt to maintain level-headedness perhaps in the methodical taking of stock of the sites that were apparently be turned into Baedekers of a future lost world. The bombs that clustered on London in the Blitz are not only preserved, but collated, in a stunning overpowering overlay that suggests a puncturing of space if not obliteration–in a collation of the sites of all German bombs dropped on London in the Blitz, September 1940-June 1941, courtesy “Bombsight“, embracing a massive repository of spatial information aggregating locations of all bombs dropped on the city.

The data is so overwhelming, of course, that the viewer is vertiginously unable to process the extent of detail it aggregates, in what might be better known as a Cartofail. The multiple maps that were made by the Bomb Damage Maps tend in the reverse: they preserve the underlying street network and sites of all buildings in the city, preserving a palimpsest that survives in the face of aerial bombardment that attempted to efface any sign of human habitation; the result is a valiant basis for the recreation of the future of London in a dark period, and a particularly healthy and plucky form of cartographic resistance, of sorts, running against the collapsing of time and space in a time of total war, by trying to retain and train attention on what exists in the city that can be preserved lest it be forgotten. In the face of total war, it is a resistance of exactitude.

The maps recall those colored glossy stars pasted, in the manner of pins, at the sites of explosions in London, which “cover the available spectrum” from silver to green, gold, red, blue, and  a surprising preponderance in certain areas of violets whose locations seem to coincide with bomb strikes, but are so  suspiciously marked with the names of women, the silver ones labelled “Darlene,” others Alice, Delores, Shirley, Sally, amidst  Carolines, Marias, Annes, Susans and Elizabeths.  The disjunction between names and places map the interior experience of Lt. Slothrop against the city that became a canvass of war, but the placid colorings of the map hues suggest a deeper disjunction between mapmaking and violence.

The maps capture an attempt to take measure of the scale of destruction, from black areas bombed out beyond repair to more lightly damaged areas in yellow, as if to process the unprecedented scale of disaster in the precision of the Ordnance Survey Maps. In ways that seemed to try to contain the violence of the bombs that killed over 9,000 by a coloring the sites that were hit by the daily assessment of bomb damages, Bomb Damage Charts drafted by the London City Council tried to process the daily destruction that took the toll of 9,000 in what Germans portrayed as revenge for allied bombers suggest an English tabulation of the ethanol-fueled violence, called as retribution for allied bombing of German cities, that revealed fingerprints of the fantasy of Wernher von Braun, the rocket scientist who was driven by truly stratospheric aspirations to reach the moon.

And they reflect, as such an attempt to map the devastation Thomas Pynchon so famously began Gravity’s Rainbow by suggesting the sudden arrival of an ethanol-fueled V-2 rocket that struck the zero Greenwich meridian around 1967, by describing a volley of ballistic missiles whose targeted strikes and explosions brought to life something like a new world, and a terrible one that is punctuated in a senseless sequence of devastating strikes.  And as Pynchon famously used the Matthausen testimonies to describe the horrors of the bombs’ production during the war by the remain side, the bomb damage maps would have provided powerful means to elaborate the destruction of the city came to map the fictionalized if troubled ever-idiosyncratic psyche of Tyrone Slothrop.  The rooftop observations of the arrival of V-2’s that arrive, arching short of the land and arriving on London, tracked by a group of Yanks, stationed at the Allied Clearing House, Technical Unites, Northern Germany (ACHTUNG), a paper warren filled with black typewriters that pose as grave markers, removed from the war but close to its violence.

As much as orient one to the destruction of bricks and mortar buildings, they suggest a way to complete the terrifying topographies of the wartime city, as familiar cityscapes suddenly vanished, taking human lives in a chaos difficult to psychologically sustain.  If Stephen Spender described how in “destroyed German towns one often feels haunted by the ghost of a tremendous noise” as it “is impossible not to imagine the rocking explosions, the hammering of the sky upon the earth, which must have caused all this,‟ evoking the inability to grasp or orient oneself to the ineffability of the sensory barrage of modern destruction with particular eloquence.  Pynchon was particularly attentive to transpose the complicated topographies of what were otherwise blank space by recourse to the “old Baedeker trick” not limited to that genre of travel books alone, but pillaging from WPA guides and other maps, in ways that make it more than likely that something like the Bomb Damage Maps provided a similar basis to orient his readers to imagining the new topography of war in which his characters sought to navigate as best they could, and the tourist maps of post-war London which rendered the continued effects of bombed out areas light green offered an effective palimpsest as any to recover the  psychological trauma of the destruction of the psychic network of place and society–

The medallions that map the routes taken by airplanes to the world’s metropoles on the first floor of San Francisco’s International airport offer curious artifacts of the first Jet Age, when air travel provided something of a miracle of linking the world’s cities in a vision of post-war harmony, even if they were only included in 2000.  For without imagining their exhaust, fumes, or the inevitable aural disturbances that are created by flight paths in the urban spaces that they boast to connect, the eloquent maps including weather isobars of inlaid brass in the terrazzo of the International arrivals terminal show the locations and arrival routes at international airports worldwide, spanning some  12,000 square feet of floor space.

They promote a triumphal vision of global interconnection, and an image of air-space that airline companies have defined, tracing the approaches to individual airports from the air.

 

APPROACHES TO OAK IN SFO

 

Today, the density of airplane flights across the world is so fantastic that the collective inscription of routes that now carry an estimated 77 million passengers a day, or a billion and half a year, placing a sizable portion of folks in the air at any given time.  The range fo flight paths that serve an estimated 3.6 billion passengers in commercial flights is so dense that OpenFlights.org, an open source logging, tracking, and mapping commercial airplane flights, map online, displace the inhabited world with a curiously organic constellations of densely overlapping paths:  the repo for storing flight informaiton offer ways to render flights on multiple projections, in ways that knit together space in fundamentally new ways.  Does the constellation of flight paths create a new organic mode of modeling spatial relations?

It is quite conceptually challenging to map actual overhead flight traffic–and even to visualize routes of national air-traffic, given their complexity and difference from most forms of travel, but reliance on similar needs to correlate flight paths, heights, and plans.  It is hard (and unfamiliar) to map sonic disturbances, even if it is familiar to map supersonic flight.  But it is fascinating to map how flight-paths impact the ground in the course of take-offs and descents: the zones where airplanes descend over cities have only recently begun to be charted.  Indeed, the multiple interests in charting airspace have only begun to be evident as airspace threatens to encroach urban space.  Indeed, if it is more accurate to map the paths of flight by the distance between global airports, the distorting crutch of a Mercator projection seems to be more recognizable–even if the density between airports so intense from Europe to America as of 2012, shown below, so as to render the contours of continents illegible, and almost erase Europe from the map–but seems so much more immediately satisfying as a way to show spatial linkages on formal grounds–if only since its curves suggest the terrestrial globe’s curvature–perhaps even more when the routes are rendered is drawn without satellite imagery of earth cover–or indeed any base layer, and focussing on airports locations alone.

Both suggest the increasing warping and shrinkage of space, but do so in ways that are oddly abstracted, given the range of data that they marshal, from the interests at stake in mapping flight paths–or in rendering the unique perspective that being in flight offers.

The very terminology we use to map flight patterns in the liminal landing areas around air strips reveal competing interests at stake in their definition, and might expose the lack of clear terminology to express the different interests of mapping flight from the position of the ground:   “fly-over” areas precede landing paths near airports; “overlay zones” around airports try to regulate the relation buildings near airports, establishing limits for building inhabited space; “noise contour maps” map impact and impingement of sound;  “overflight zones” animal sanctuaries’ exposure to flight-paths. The “fly over zone” oddly suggests the remove of the airplane to lived space, even as such maps map the impact that flight landings have on residential areas.  We used to refer to the “fly-over zone” in dismissive tones as the area between the coasts led them to hop between New York, Los Angeles, San Francisco, Seattle or Boston with little contact with those areas between–but also to conceal some anxiety at the limits of this constrained geographic awareness–increased density of air-traffic that threatens to max out runways make overlay zones  into potentially contested areas in need of mapping.

The interests are at stake in the commercial expansion of airports and the determining the criteria for the limits of acceptable levels of environmental noise and pollution.  While maps locate specific sites of population in a universal matrix, the impact of the descent and take-off of airplanes on urban space suggest a troubling overlap of navigable airspace, a wooly and capacious category that conceals its overcrowded nature, and inhabitable land, focussing on the grey zone on the margins of the airport.  To get our heads around airspace, whose considerable scale is almost unfathomable, let’s try to examine the impact of its contours on urban space in this post. The sociologist Henri Lefebvre drew a distinction between the production of representations of space, of social spaces, and of individual mental representations of space in The Production of Space, when he sought to capture the diversity of spatial production within the city’s everyday life:  Lefebvre argued relations between the production of social, the representation of space, and the space individuals represent to themselves demanded attention as distinct tools or “spatializing practices” in urban space, if not the political character of the social production of urban space.

But Lefebvre didn’t consider airspace within this constellation–a space that exists outside but on the margins of social space–but it is a qualitatively different image of a commercial space that has been increasingly imposed upon lived space or inhabited space without much planning or regulation–particularly when it comes to take-offs and descents, the main focus of this post.  The mapping of the incursion of airspace on lived space It’s perhaps not only a coincidence that since Lefebvre’s book appeared in the early 1970s, inter-city airline travel has boomed as a social sphere, if not a space in and of its own right, often removed from urban space but on its margins.

And paths of flight have only begun to be mapped in their diversity.  The density of air-traffic indeed may have even changed our perception of space in complicated ways, with both the rise of faster planes and long-distance flights and the common nature of air travel and of plane arrivals as common ways of entering cities or departing from them.  And landings and departures, from commercial airline travel or air transit to air transport to unmanned flights, has begun to impinge in increasingly perceptible ways on lived space.  The lived space below the webs of air travel, take-offs, and landings suggests a persistence of place in a geography of flight, as in places that are crisscrossed with air routes, airplane flight is too often naturalized as white noise.  “[The noise] bothered me until I realized that, when I hear the planes, it’s always a reminder that there is life out there, and people are traveling, and traveling is a big part of me,” noted a Turkish immigrant living by the San Diego International Airport with some stoicism in 2005, trying to look at the upside of this rumbling that then punctuated her day in 15 second interruptions, coming roughly often every minute and a half.  “So even if I can’t go home to Turkey and visit my family,” she reasoned, “I know that there’s this possibility that one of them could get on a plane or that I could get on a plane and go back.” Most flight travel in the United States are primarily supervised not by localities, but the Federal Aviation Administration.  The legal status of restriction to these paths is limited or constrained by the fact that no general policy seems to exist–indeed, the FAA is slightly compromised in its interested in fostering commerce, as much as protecting the safety of urban space or local rights, and has limited ability as a national organization to mediate between local residents’ desires as it negotiates the interests in maintaining commercial hubs to foster the expansion of commercial national airspace.

When I was in San Diego last weekend, the close proximity of the airport to the harbor and marina made me think of the huge growth in airspace in past decades, and difficulties of mapping airspace in American cities.  The huge expansion in air traffic since the initial growth of airports in the 1950s, combined with recent growth in belts around cities and in formerly extra-urban areas have led to a common phenomenon of living in or on the margins of an overlay zone, in cities like San Diego.  Although  issues of noise were not a problem in the early age of airports in the United States, dominated  by smaller-sized planes and far fewer flights, since the expansion of non-stop nation-wide flights in the 1960s,  commercial cargo services have created a new geography of air flights and air use, and an increased  intensity of air travel at hubs, as well as the consequent expansion of a huge web of air travel, with attendant plane landings and take-offs, that create a virtual web of crisscrossing flight-paths across the country. Mapping the navigation of individual routes is far more direct.

Yet the image of a nation bound by flight-paths of different carriers already seems to wrap itself in a serpentine fashion around the geographic map.  Basing his work on a mine of FAA data, Aaron Koblin’s “Flight Patterns” uses data to track flight-paths to map of our active airspace–an image of which we are rarely conscious and constitute a maze difficult to spatially comprehend, but whose ghostly network exists around nodes of airline hubs and links arcs of aerial paths.  (This is a hard balancing act:  NASA indeed predicted in 2007 that allowing computer software such as Terminal Sequencing and Spacing to remotely coordinate the flights of the aircraft that simultaneously course across the skies would not only increase the regularity of landings and take-offs at airports but allow airplane companies–perish the thought!–to be a blue to manage an increased density up to twenty percent by utterly banishing human controllers from the scene.

In a finding appealing to cost-cutters, NASA forecast that the combination of more autonomous planes and increasingly automizing traffic control would bring a significant savings to airplane companies; the prospect of switching to automated copilots alone might reduce labor costs in passenger aircraft by some billions of dollars every year.)  The wonderfully organic image of the flight paths across the country seem to render something like an Indonesian stick map.

Our awareness of the rapidly growing density of flight paths may be masked by the mental images we receive from personalized in-flight tracking maps, which perpetuate an illusion of navigating the airways or wile away hours by mapping progress to a destination one rarely registered consciousness of traveling toward, sitting in an isolated cocoon at 60,000 feet, as if we were pilgrims bravely undertaking a cross-country trek, accentuating our experience by wildly magnifying the plane out of any relation to the map on which it is super-imposed.

This map has a wonderful ability to place us in a sort of  relation to a local environment:  we are the bright green moving icon, launched on a dotted line across the country, as we try to equate our perspective with the projected flight path over the screen of a static map. Contrast this, say, to the sort of snapshot that Anthony took at the National Air and Space Museum in Washington of the planes in flight above the country at a moment in 2006, that led him to “imagine the pressure of Airport control conductors . . . at major airports” as they managed flights’ course:

 

Airplane Flight Maps

  Of course, the icons of individual planes, which seem about the size only slightly smaller that seen by observers on the ground,  wildly out of scale in relation to the background map of the United States, so that they seem to crowd the skies  like buzzing flies.  It is somewhat reassuring that there are directional corridors of national travel across the country, we can see in a map of flight paths; the density of the lines boggle the mind even when we distinguish flight paths at over 30.00 feet, and we face only a ghostly spider’s web of blue and green streams that designate the arcs of inter-city flight paths:

 

Traffic avobe 30,000 feet

 

Even looking at the Bay Area alone, it’s hard to get one’s mind around the inhabitation of the sky above 30,000 feet, marked as they are by streaks, and contrary to the idea of inhabitation as well as covering a space greater than most can intellectually comprehend:

Given the need to maintain protection for wildlife sanctuaries, there is a considerable body of maps regulating overflight altitude above protected populations of marine species.

Such maps don’t address urban space, but they do suggest the problems of defining similar overflight regulations of areas human residents inhabit.

It’s less hard to comprehend crisscrossing paths of air-travel from outside the passenger seat.  We can imagine and track the divergence of commercial airspace from a ground-bound perspective as it impacts a city’s social space.   The government-sponsored expansion of airspace has in many ways created an odd and un-natural urban geography between pathways of flight and urban residences:   fly-over zones are mapped over and on top of social space, and airspace as mapped over lived space.  The relation of fly zones to personal  is not only figurative; fly-over zones impinge in concrete sensory ways on the mental space of the individual, which is now permeable to the  unnatural rumble of the turbines overhead.

What’s it like to live under a flight path?   The protection of airspace by the FAA makes it not the best government agency to represent how planes impinge on the ground:  the mapping and protection of flight paths creates a bit of a super-jurisdictional commercial space with limited attention to how flights permeate the mental space of nearby residents.  As if some would naturalize the rumble of a nearby volcano, a sandstorm, or the Santa Ana winds, there’s the knowing acknowledgement, with a shrug, at the convergence of the airplanes overhead.  (This is a soundscape that is worth recording in its entirety, of which the  YouTube video below offer a more condensed time-stop spliced condensation that doesn’t really capture the improbable regularity with which cruises intrude on the sunny street-scene.) Let’s examine the ways airspace is mapped.  Indeed, the FAA has recently been required to publish a set of “noise exposure maps” or NEMs for public notice, as the 1969 National Environmental Policy Act omits airplane noise.  They hope to provide an open forum or acknowledge public input to  the environmental impact of increased air traffic, responded to local resistance to the adverse environmental effects of expanding airports in WisconsinFlorida, Toronto, CharlotteArizona, Sacramento, and elsewhere, given the conflict of interest for the FAA in negotiating local noise regulations and  improve commerce through air traffic as they seek to prevent the expansion of commercial areas around airports that are increasingly becoming engulfed in extra-urban space. But it is the impacting of areas of inhabitation with air-space that creates perhaps the stickiest situation for mapping flight travel for the FAA, and poses the deepest problems of how we expand our airspace at the same time as curtail the impact of that airspace on something we might call quality of life, but has much larger consequences and implications than that numinous and intentionally generic term implies.  Fly-over zones near San Diego exemplify air-traffic appears about to max out , as expanding airspace impacts residential space. The frequent the flights at San Diego International Airport over residential space at a distance as close as 400 feet does not seem a great feat of modern urban planning:  nestled near the port of Coronado, right by Highway 5,  the airport is a stone’s thrown away from the city’s Marina and three miles from the Pacific.  Perhaps this relates to the fact that the city is a long-time base for the military, with it’s own frequent air-shows and culture of naval and air-force bases.  But the expansion of the city around the town of Coronado has paralleled a transformation of the former Lindberg Airport to a three-terminal sprawling cluster of buildings, maximizing its use in response to economic development of the city, apparently naturalized within the coursing freeways that surround it, while dealing with only two runway zones.

 

Airport Overlay--San Diego

 

 

Planes fly overhead at a distance that seems roughly equal to a football field.  In a manner that provides limited negotiation between local inhabitants and the regulation of airspace, we find only the most general stipulation in Part 91, Title 14 in the Code of Federal Regulations about maintaining a minimum altitude of 1,000 feet for air travel over “congested areas,” which is waived in the event of take-off or landing.  And any restriction on airport use or control of flight paths depend on the approval of the FAA, according to the Airport Noise and Capacity Act of 1990 (ANCA), an approval that must rest on demonstrating that any restriction isn’t a curb or impediment to interstate commerce and is “not inconsistent” with “safe and efficient use” of “navigable” airspace:

The airport restricts or “disallows” take-offs in the wee hours of the night between 11:30 pm and 6:30 am but with over 600 departures and arrivals each day and growing, the distinctive combination of a rumble and high-pitched reedy whine from planes that literally fly over apartments at a distance of as close as 400 feet create an inescapable part of the aural environment of urban spaces–with noise levels averaging 150 dB at 100 feet.  The delineation of precise paths of approach airplanes must take to the runway creates the working framework to descend over six-lane freeways to enter the area ringed by palm trees right by San Diego Bay and the old Marina.  It all seems pretty disordered when one enters on commuter plane, but the pathways of arrival are mapped in detail, allowing one to enter along the following elevations, which seem designed to encourage a slow approach from the ocean or inland into the two runways, avoiding the City of San Diego or Mission Bay area, for which landing would require a far more precipitous route of descent, and would anyway be discouraged by the orientation of the field’s two major runways:

 

Airport Approach Overlay Zone

 

These points of entry overhead are in a sense defined.  But the dramatically rising number of flights that land or take off to the East create a sizable amount of traffic, rumbling as they do.  While the restriction of the heights of buildings in the pathways of flights are legislated to be no taller than forty feet, there seem to be a way to guarantee safety by not impinging on residential areas in region where 10,000 houses and over 20,000 residents are packed, in a combination of rental apartments and condos.  Of course, most residential areas in California are made up of houses of less than forty feet, anyways, so while this dedicated to the safety around airports and clear runway views for pilots, the restrictions on elevations in the above map–a sort of contour map of the minimum elevation of flight paths–try to map the boundaries that determine relations of airspace and lived space. Overlay zones protect the more verdant Mission Bay area, the more desirable ocean residence, the mid-century area around the city of Coronado–now a suburb whose harbor just getting its first restoration of buildings ringed by palms–creates the backdrop for approaching flights whose entry zones offers an eery aural backdrop oddly incongruous with a harbor populated with small boats sailing at full sail.  The approach of large airplanes over the bay is encouraged, with access from the west, over the Pacific, while restrictions limit flights over San Diego itself.   Guidelines of air travel encourage pilots to descend from the Pacific or over the harbor by two routes of approach, avoiding low travel over the protected Mission Bay area and making convenient two access lanes:

 

Airport Approach Overlay Zone

 

But Lindberg was expected to exceed its capacity for air travel by 2015, and there is now no clear alternative to remapping flight density or flight paths in sight. The mapping of air travel around the city, as it were, reflects the constitution of layover zones where flights are restricted over more inhabited areas.  In such maps, routes of flight are granted near-legal precedence over the priorities of folks who live under flight-paths, since commerce must be protected over all.  (This might include, for example, the importation of high-grade Sushi from Japan, on its way with JAL cargo jets for consumption in high-end restaurants in Las Vegas, or a slew of FedEx planes ready to depart, as well as all those commuter flights to Los Angeles.)  While privileging commercial needs seems reasonable, one would not of course expect landings or take-offs to occur in densely inhabited areas anyway, so the stipulation seems bureaucratic legalese, with limited ramifications.  Yet since “neither the City of San Diego nor the State of California can regulate the altitude, speed, location or direction of aircraft in flight,” the road is literally open to free market expansion of flight routes, especially if market forces dictate the creation of airstrips situated cheek by jowl beside residential areas. In much of the nation, the original sites of airports built and constructed some fifty to seventy years ago were planned in areas then outside of the city limits, outside of settled zones.

The expansion of the airport as a hub has led to further construction of buildings in the seventies and eighties, even as their location is increasingly taken over by urban sprawl to such a degree that they’ve been swallowed up in the city itself–if still not in what constitutes its most “congested areas.”  Since it was legally stipulated no buildings be constructed within fifty feet of FAA-established approach paths to the airport, with the exception of those less than 40 feet in height, a large number of relatively short buildings cluster around the flight approach paths at San Diego International Airport’s Lindberg Field.  In other areas of the country, the FAA has turned its attention to the impingement of “development creep” around airports formerly located at a remove from  populated areas, but now more ringed by malls and housing developments and residences, creating a need to impose overlay zones to protect  “public investment in airports,” as much as safety–several airports less economically important have been forced to be closed because of development creep. The FAA, meanwhile, has been legally required to make public  limits of permitted airport noise on the internet in a set of “sound contour maps,” to map the neighborhoods and residential areas impinged by airport noise, as this map of the area around LAX, which restricts approaches to from the east and west, in an attempt to reduce noise pollution in more affluent areas whose property value could be compromised, and only marginally create intrusive noise pollution from residential inhabitants, cast here as if the mitigation of noise exposure imitated the orientation of runways, and conveniently sidestepping issues of noise pollution below the approach corridors of most flights in poorer neighborhoods:

 

LAX Sound Contour Map

 

 

The desire to “make [available] noise exposure and land use information from such noise exposure maps [prepared under 14 CFR part 150] . . . in an appropriate format” created a neat set of contour maps for Oakland in 2006, which took advantage of the planning of the airport along the Bay over which it places the greatest square footage of noise, and effectively removes anything over 70 dB–the sound of a car engine from fifty feet away–from all but a few inhabitants:

 

Oakland Airport

Yet is the distribution of noise is difficult to steer from urban areas, mapping the impact of noise impingement has led to some dramatic improvements in levels of airline noise in some residential areas, as around Midway Airport, a small one to be sure, which suggests a considerable reduction over time of the level as of fly-over noise from planes in Chicago:

Midway International Airport Noise Contour Map

 

The selection of maps raise questions about the monitoring, measurement, and dissemination of models of noise-reduction, to be sure.  The FAA seems to clearly desire to project an image of making these maps available for easy download and consultation, as if to give a sense of transparency to the problem of noise pollution in overhead flights, and to convey a degree of public trust.  But there is a   countervailing tendency to naturalize the map, and to naturalize the overhead flight zone, which stacks the cards against any attempt to effectively monitor the impingement of flight zones in areas of urban life, or prevent an idea of the importance of reducing ambient sounds from the social space of urban areas.  Once the threshold is established, to be sure, acceptance is on the way.  Unclear local means of redress  exist, despite the availability of maps online, and we still haven’t assessed acceptable limits for airport noise or the elevation of overhead flights. Sure, in San Diego there’s a lot of pleasure in seeing the planes enter the urban airspace for some air shows– –that echoes how my mother was taken by her parents in the 1940s to watch the planes land and take off at La Guardia Airport on the Flushing Bay waterfront in Queens New York, then the New York Municipal Airfield.  But there’s a danger we naturalize airport noise not in the environment, among the quite variegated sound map of urban life from motorcycles to tow trucks and diesel trucks.

 

Sound Map of Missionjpg

 

And, more deeply, there’s the criteria question of whether one means sounds, or the potential other effects of airplanes flying close overhead, and entering inhabited residential areas that are filling up the areas around extra-urban areas.  Isolated motorcycle sounds are the greatest dB count on Saturday morning in the mission, and the neighborhood is spared the sonic intrusion of flight paths.  The effects of that much noise pollution around LAX or SAN have already been removed from the table, perhaps as demand for airspace remove public input for the design of a map of urban airspace off the map. Such planned flight paths that skirt the crowded or more affluent areas of urban residence doesn’t, of course, even start to take into account the density of a map of unmanned flights across the country.  At the risk of caving into the fears of the right wingers, the pleasure many CIA operatives took in their use of drone flights as a relatively error-free incursion into foreign airspace seems an odd extension of the resolution of problems of mapping air flights by legitimizing rising air traffic over residential areas.  There are, of course, entirely other way of raising questions about the pretty clouded ethical issues of occupation of airspace by unmanned objects–but the uses of attack planes to arrive at positions that cel phones or GPS locates suggest an expansion of their coverage of airspace.

 

flight-route-airspace-chaos

 

Remotely piloted aircraft are so densely flown over the country, if this chart is to be believed, that one can’t but wonder about the ways that our current process of mapping flight “overlay” zones around airports relates to the bartering for access to foreign airspace–or the legal wrestling with the notion that a government can barter or grant off rights for sending unmanned drones into populated areas.  We have coerced the ISI into agreements that all drone flights over Pakistan operate under covert US authority, in other words, and silence be preserved over the invasive nature of their entry into foreign airspace with a mission to kill. In the process, we’ve ceased to defend or see as legitimate a process of open local negotiation about the organization of airspace, even though many of the casualties are nearby residents in the wrong place at the wrong time; the Central Intelligence Agency presumes or assumes airspace rights and flight zones as legitimate tools to target individual inhabitants, in ways that would have little legal justification fifteen years ago.  There seems some parallel in the trade-offs with which we’ve decided, rather than boost the local economy, to protect increased commercial traffic, and to legislate permissible zones of approach, and let the residential market take its own path.  To do so may map an inevitable collision course between airspace and lived space by affirming the exposure or vulnerability of our spatial situation in the face of air traffic above.
