The Bell X-2 turned into a rocket-powered studies plane mutually evolved by Bell aircraft organization, the U.S. Air force and the national Advisory Committee for Aeronautics (the precursor to NASA) in 1945. The plane become constructed to research aerodynamic problems with supersonic flight within the Mach 2 to Mach three range.
The X-2, nicknamed "Starbuster," finished its first powered flight in November 1955. the following yr, in September 1956, Captain Milburn Apt changed into at the controls while the X-2 reached Mach 3.2 (2,094 mph, or three,370 km/h), at an altitude of 65,000 ft (19,800 m).
rapidly after attaining this top speed, however, Apt attempted to show the plane while it turned into still above Mach 3. The aircraft tumbled out of manipulate, and Apt's tries to get over the spin failed. This tragic twist of fate ended the X-2 software, after a complete of 20 take a look at flights.
