A Grand Canyon site containing wreckage from a 1956 plane crash has been officially designated a National Historic Landmark, the National Park Service announced last week. A TWA Super Constellation L-1049 and a United Airlines DC-7 collided in uncongested airspace at 21,000 feet above the canyon, the Park Service said, killing all 128 people aboard both flights. The accident spurred efforts to modernize and increase safety in the nation's airways, leading to the Airways Modernization Act signed into law by President Eisenhower in 1957, a prelude to the establishment of the FAA. Hundreds of pieces of wreckage, along with craters and other evidence of disturbance from the crash, remain at the isolated site, which comprises about 1.5 square miles.
