Un site de crash aérien devient monument historique national

 1956 Grand Canyon TWA-United Airlines Aviation Accident Site

C'est la décision étonnante qui a été prise d'accorder le titre de National Historic Landmark aux parages d'un crash aérien qui a eu lieu aux USA le 30 Juin 1956.
 

 On June 30, 1956, a Trans World Airlines 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. Other improvements that resulted from the crash included nationwide radar coverage, a common military/civilian navigation system, and the development of technologies such as collision avoidance systems and flight data recorders.
