| 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 hooks and strap that holds the X-1 in place under the B-29 can be seen just above the hand of the technician with the hose. The strap continues under the belly of the X-1 and holds the aircraft to the mothership until the word comes to "launch", and then the shackles are released. |

| Bell X-1 known as "Queenie," is mated to the EB-50A The third X-1 (46-064), known as "Queenie," is mated to the EB-50A (46-006) at Edwards AFB, California. Following a captive flight on 9 November 1951, both aircraft were destroyed by fire during defueling. This particular X-1 only flew twice, the first flight occurring on 20 July 1951. Bell pilot Joseph Cannon was the pilot on both flights, although the second flight was only a captive flight. Cannon was injured in the fire. |

The painting near the nose of the B-29 depicts a stork carrying a bundle which is symbolic of the Mothership launching her babe (X-1-2). The pilot access door is open to the cockpit of the X-1-2 aircraft. On the X-1-2's fin is the old NACA shield, which was later replaced with a yellow band and the letters "NACA" plus wings that were both black. |

NACA Flight 33 was flown on September 23, 1949, as a pilot familiarization flight with NACA pilot, John H. Griffith at the controls. Griffith reached a top speed of Mach 0.998 during the flight. |

| X-1 pilots Robert Champine and Herbert Hoover The Bell Aircraft Corporation X-1-2 and two of the NACA pilots that flew the aircraft. 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. |

| Bell X-1 in high speed flight The Bell Aircraft X-1-1 (#46-062) in flight. The shock wave pattern in the exhaust plume is visible. The X-1 series aircraft were air-launched from a modified Boeing B-29 or B-50 Superfortress bombers. The X-1-1 was painted a bright orange by Bell Aircraft. It was thought that the aircraft would be more visable to those doing the tracking during a flight. When NACA received the airplanes they were painted white, which was an easier color to find in the skies over Muroc Air Field in California. This particular craft was nicknamed "Glamorous Glennis" by Chuck Yeager in honor of his wife, and is now on permanent display in the Smithsonian Institution's National Air and Space Museum in Washington, DC. |

| Bell X-1 Flight instrumentation Bell Aircraft Corporation X-1 series aircraft on display at an Open House at NACA Muroc Flight Test Unit or High-Speed Flight Research Station hangar on South Base of Edwards Air Force Base, California. The instrumentation that was carried aboard the aircraft to gather data is on display. The aircraft data was recorded on oscillograph film that was read, calibrated, and converted into meaningful parameters for the engineers to evaluate from each research flight. In the background of the photo are several early U.S. jets. These include several Lockheed P-80 Shooting Stars, which were used as chase planes on X-1 flights; two Bell P-59 Airacomets, the first U.S. jet pursuit aircraft (fighter in later parlance); and a prototype Republic XP-84 Thunderjet. |

| Bell X-1 at Muroc Air Field The Bell Aircraft X-1-2 aircraft on the ramp at NACA High Speed Flight Research Station located on the South Base of Muroc Army Air Field in 1947. The X-1-2 flew until October 23, 1951, completing 74 glide and powered flights with nine different pilots. The aircraft has white paint and the NACA tail band. The black Xs are reference markings for tracking purposes. They were widely used on NACA aircraft in the early 1950s. |

The gages reflecting the airplane's parameters such as indicated pressure altitude, indicated airspeed, rocket chamber pressure, fuel and liquid oxygen supply, angle of attack, angle of sideslip, and Mach number are shown. Other information pertinent for the pilot to complete a successful flight is also displayed. |

| Bell X-1E modified canopy This photo appears to depict the design of the X-1E canopy, the X-1-2 was modified. The modifications included a new thin wing and a low-pressure fuel system and the most visible change was a raised canopy that replaced the original flush windshield on the aircraft, which was called the X-1E. |

This is an early 1950s color photo of NACA research aircraft in front of the South Base hangar. On the left is the third D-558-2 (NACA 145/Navy 37975). At this time, the aircraft was still in the combined jet and rocket configuration. NACA 145 was used to test a number of wing modifications intended to lessen the pitch up of the aircraft in turns. |
