At 10.31 am, on 30 June 1956, TWA & UAL airliners collided mid-air over the Grand Canyon, Arizona, USA, & crashed into the Canyon. All 128 people on the airliners perished. At the time, it was the worst aircraft accident in the USA. It shocked the nation & the world. It led to the eventual radical improvement in ATC through changed procedures, new technology & more personnel. Hope this video helps us to fly even more safely.
