LLRV Test Flights

The Lunar Landing Research Vehicles (LLRVs) were informally known as the "flying bedsteads". These vehicles were created by the NASA Flight Research Center (which later became Dryden Flight Research Center) to test technology and flying techniques for the upcoming lunar landings. Following the success of the LLRV vehicles, NASA created three Lunar Landing Training Vehicles (LLTVs) to specifically train astronauts.
