In 1956 two plane collide over the Arizona desert , killing all 128 people on board and scatter the debris deep inside the Grand Canyon . This week , the National Park Service designated the crash internet site a National Historic Landmark — even though they do n’t really require you to go visit it .
At the clock time , the tragedy was the deadliest civilian aeroplane crash on American soil . It also served as a annihilative wakeup call to the fledgling airline industry , which was ache from growing pains and lack of government reenforcement .
A United Airlines DC-7 and TWA Lockheed L-1049 Super Constellation both left LAX on the morning of June 30 , 1956 , the United flight lead to Chicago Midway and the TWA flight headed to Kansas City . Both plane were vanish at different altitude in uncontrolled air space when the TWA flying call for permission from air dealings control to fly at higher than normal altitudes due to electrical storm . Air traffic control say no , due to the United flight nearby . Then the pilot film requested to rise above cloud point , operating under optic flying rules or VFR ( instead of instrument flight of stairs rules ) . It was interpret that at this altitude , the pilot would be engage the “ see and be see ” principle — responsible for visually spotting and avoid aeroplane nearby .
The planes cognise they would be share air space but did not have any way of knowing they were in such faithful proximity . It ’s also probable that both planes were off - path slightly to show their rider the scenic landscape below . As the two pilots steer over the Grand Canyon , cloud in all probability obscured their views , and the planes collided at a 25 - arcdegree angle .

Although there ’s a sepulture site for the TWA passenger in nearby Flagstaff , Arizona , the clangoring site itself has never been formally acknowledge . For one , they ’re not exactly sure where the crash itself befall . The plane hit the primer at 700 foot per second near the confluence of the Colorado and Little Colorado Rivers . Each heat fires that were so spicy they fused the body of the carpenter’s plane onto the canon Rock . No body were recovered integral .
There are parts of the planes which continue at the bottom of the canon ; due to the treacherous terrain it was impossible to recover all the pieces . But also due to that punic terrain , the National Park Service is not revealing the precise placement of the clash website because it does n’t require people hike there . ( Althoughplenty of people do . )

So why even have a turning point at all ? In this case , the landmark status is more about the modification this situation bring in about . Because of the crash , the country enacted sweeping reforms for communication and guard for the airway industry . Due to the great press coverage the crash received , the world was outraged , and there was a movement to exact congressional hearings about the case . Between 1950 and 1955 there had already been 65 mid - air collision over U.S. airspace .
In 1957 , a motion was introduce to advance breeze traffic control financial support , both to modernize the organization and hire and train controllers . This would include ways to better manage visual and instrument flight rules . drome also added radio detection and ranging , which would turn out invaluable for cut through planes . And a few years later , the Federal Aviation Agency was shape to supervise all American air space .
Although memorials for crash site are commonplace , this is the first time a plane crash land site has been landmarked . And it ’s also the first landmark which technically honors something which happen in the air , not on the ground , National Historic Landmarks Program ramification chief Alexandra Lordtold The Atlantic Cities :
“ We ’ve never done an actual clank site , ” enjoin Alexandra Lord , limb tribal chief of the National Historic Landmarks Program in Washington , D.C. “ In some way we can reason that the crash itself — which led to the scattering of piece over a vast detritus field — is what ’s all-important . And it sort of does n’t matter if you think of it as on the atmosphere or on the ground . ”
Next metre you ’re flying over the American Southwest and your pilot tell you to look out the window to see the Grand Canyon , lie with that the ground you ’re flying safely is because of that site somewhere below . A single tragic clash goad along the engineering that made the skies a better place for all . And for that , a watershed is very fitting indeed . [ Atlantic Cities ]
