On Tuesday, July 8, 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. On June 30, 1956, a Trans World Airlines (TWA) Super Constellation L-1049 and a United Airlines DC-7 collided in uncongested airspace 21,000 feet over the Grand Canyon in Arizona, killing all 128 people onboard the two flights. The tragedy spurred an unprecedented effort to modernize and increase safety in America’s postwar airways, culminating in the establishment of the modern Federal Aviation Administration. The National Historic Landmarks Program, established in 1935, is administered by the National Park Service on behalf of the Secretary of the Interior. The agency works with preservation officials, private property owners and other partners interested in nominating properties for National Historic Landmark designation. Completed nominations are reviewed by the National Park System Advisory Board, which makes recommendations for designation to the Secretary of the Interior. |
