| USAF Captain Charles "Chuck" Yeager pilot of the Bell X-1 USAF Captain Charles "Chuck" Yeager pilot of the Bell X-1, October 14, 1947. On October 14, 1947, with USAF Captain Charles "Chuck" Yeager as pilot, the X-1-1 flew faster than the speed of sound for what is generally accepted as the first supersonic flight by a piloted aircraft. Captain Yeager ignited the four-chambered XLR-11 rocket engines after being air-launched from under the bomb bay of a JTB-29A (#45-21800) at 21,000 feet. The 6,000-pound thrust ethyl alcohol/liquid oxygen burning rockets, built by Reaction Motors, Inc., pushed him up to a speed of approximately 700 mph, or Mach 1.06, at an altitude of 43,000 feet. Chuck Yeager named his plane "Glamorous Glennis" arter his wife Glennis. |

The one on the viewer's left is Robert Champine with the other being Herbert Hoover. Champine made a total of 13 flights in the X-1, plus 9 in the D-558-1 and 12 in the D-558-2. Hoover made 14 flights in the X-1. On March 10, 1948, he reached Mach 1.065, becoming the first NACA pilot to fly faster than the speed of sound. |

| X-1E during engine test, Edwards AFB The Bell Aircraft X-1E during a ground engine test run on the NACA High-Speed Flight Station ramp near the Rogers Dry Lake. The rocket technician is keeping the concrete cool by hosing it with water during the test. This also helps in washing away any chemicals that might spill. The test crew worked close to the aircraft during ground tests. |

| X-1E lands with nose gear failure June 18, 1956 on Rogers Dry Lakebed after Flight 7 of the Bell Aircraft X-1E with NACA High-Speed Flight Station test pilot Joseph ‘Joe’ Walker at the controls. The first generation X-1s were well known for nose gear failures and the X-1E was no exception. The hard pitch down on landing usually resulted in a collapsed nose gear. The damage rarely was serious but required several days of down-time for repair. The X-1E was the only one to have a true tail skid to protect the empennage from over-rotation during landing. |
