Two airliners collide in mid-air over Grand Canyon in Arizona, leaving 256 dead

Two planes, a Super Constellation and a DC-7, departed Los Angeles minutes apart and vanished in heavy thunderclouds over the Grand Canyon. The wreckage was found scattered near the Colorado and Little Colorado rivers, with theories suggesting a mid-air collision. The challenging terrain and turbulent winds complicated recovery efforts. An Air Force helicopter eventually accessed the site. The Civil Aeronautics Board plans a public hearing to investigate this tragic event, marking it as the worst commercial aviation disaster in history.
