Watch: NASA Reveals 70 Years of Secret X-Plane Footage
Grab your tinfoil hats, folks, because we're discussing NASA secrets. No, not greys and reptilians, we're talking about secret flight tests. NASA's Armstrong Flight Research Center, originally the Dryden Flight Research Center, has been flight testing for a whopping 70 years and is celebrating that anniversary by releasing over 200 videos of flights never before seen by the public. But no longer—take a look inside decades of secret flights and experimentation. It might not be Area 51, but it's still pretty cool.
Here's a video from 1991, a NASA SR-71 Blackbird refueling in mid-air.
Here's an experimental, unmanned flight from 2004. This is the Pegasus X-43A hypersonic aircraft, flying over the Pacific Ocean.
Here's another experimental hypersonic craft, the X-15, as it flies over the Mojave Desert. This aircraft was a part of NASA's experimental "X-plane" series. This plane could reach speeds of up to 4,520 mph all the way back in 1967. Not too shabby.
