Plane Type: Bell X-1B

The X-1B was the second in a series of rocket-powered experimental research airplanes designed for investigation of various problems associated with supersonic flight. Specifically, the mission of the X-1B was flight research pertaining to aerodynamic heating and pilot reaction control systems. It made its first powered flight on Oct. 8, 1954.On all test missions, the X-1B was carried to launching altitude, normally 25,000-35,000 feet, nestled under a modified B-29 Superfortress "mother" airplane. It was then released in mid-air and rocket power was applied and, under full throttle, flights lasted less than five minutes. After all fuel (an alcohol-water mixture) and liquid oxygen had been consumed, the pilot glided the airplane to earth for a landing. Frank K. "Pete" Everest Jr. flew flights #9 & #10 November 30, 1954.
