X-1B

X-1B
Credit: NASA

American manned rocketplane. Flown 1952. The X-1A, B, and D were essentially identical rocketplanes intended to reach speeds above Mach 2.

Status: Operational 1952.

The X-1A and X-1D were destroyed in in-flight explosions; the X-1B survived, training future moon lander Neil Armstrong on its last flights in 1958.
