Sound Barrier Cracked
Edwards, United States
On October 14, 1947 42,000 feet above this monument, Captain Chuck Yeager, USAF, piloting a Bell X-1 rocket airplane named Glamour Glennis, became the first person to exceed Mach 1. With this flight, the era of supersonic aviation was born. This monument honors that flight, the aircraft, a loyal ground crew, and its valiant pilot.
