On October 30, 1964, NASA's Lunar Landing Research Vehicle, or LLRV, took to the skies for the first time. The LLRV was a bizarre, four-legged flying contraption commonly known as the "Flying Bedstead." NASA used it to simulate moon landings and liftoffs on Earth to prepare for Apollo 11, the first crewed lunar landing. The first person to give it a whirl was the X-15 pilot Joe Walker. During this test flight, he reached an altitude of about 10 feet, and he hovered there for about a minute. He did this two more times that same day. In all, he completed more than 30 test flights with the LLRV. These test flights took place at NASA's Dryden Flight Research Center in Edwards, California. That facility has since been renamed the Armstrong Flight Research Center after Neil Armstrong, who also piloted — and famously crashed — the "Flying Bedstead" before he went to the moon.The first Lunar Landing Research Vehicle is pictured during a test flight at NASA's Dryden Flight Research Center in California.

While images from this test flight might look like the team are having a bit of fun out in the desert, and perhaps they were, it was also deadly serious. The astronauts who signed onto these crewed missions were doing something that had never been attempted. They were putting their lives on the line for this progress, and this testing was a major piece in reassuring them and NASA that lunar landing could be accomplished, and safely. Today, as we return humans to the moon with NASA's Artemis program, we see parallels between testing done over 60 years ago and testing today. Right now, SpaceX and Blue Origin are testing their lunar landers for crewed lunar landings in the near-future. While we have now been to the moon and have safely and successfully landed humans before, these tests remain critical for the safety and success of the missions. Want more space history?
