Grand Canyon: TWA Flight 2 and United Airlines 718

The 1956 Grand Canyon mid-air collision occurred on the morning of Saturday, 30 June 1956 when a United Airlines Douglas DC-7 struck a Trans World Airlines Lockheed L-1049 Super Constellation over the Grand Canyon in Arizona, resulting in the crash of both airliners. All 128 passengers and crews on board both flights perished. It was the first commercial airliner crash to result in more than one hundred deaths, and led to dramatic changes in US flight control systems, including a $250 million investment to improve the air traffic control system, and the creation of the Federal Aviation Administration. There haven’t been any mid-air collisions in 47 years.
