The 1956 Grand Canyon mid-air collision occurred on Saturday, June 30, 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 planes, 128 fatalities, and no survivors. It was the first commercial airline crash to result in more than one hundred deaths, and would lead to sweeping changes in the control of flights in the United States.

In 2014, the National Park Service (NPS) dedicated one of the nation’s newest National Historic Landmarks, the 1956 Grand Canyon TWA-United Airlines Aviation Accident Site in Grand Canyon National Park. This site commemorates a horrific airline collision over the Grand Canyon in 1956.

The public dedication ceremony of the National Historic Landmark designation took place at the Desert View Amphitheater looking out toward the crash site. This ceremony remembered those who perished in the crash, recognized the significance of the accident, and acknowledged family members and friends of the crash victims.
