[Lunar Landing Research]

Nicknamed the "Flying Bedstead," the Lunar Landing Research Vehicle (LLRV) was created to simulate landing on the Moon in the Lunar Module. As such, its 4,200-lb thrust turbojet engine and 18 different rockets were designed to cancel out 5/6ths of the LLRV's weight, thus simulating the gravity on the Moon. Despite a number of accidents in training — including Neil Armstrong's famous ejection from the vehicle on May 6, 1968 — the "Flying Bedstead" remained an essential tool in NASA's program to land humans on the Moon safely.
