Back in 2006, the Space Shuttle Atlantis was in orbit above the planet when the crew notice something strange in the distance. Three metallic looking objects all moving independently from each other are spotted and reported to NASA in Houston. Naturally NASA are not buying the UFO thing and suggest that its several things such as reflections, but the crew insist that they are solid and as normal with this one you are going to have to make up your own mind!
According to crew of the Space Shuttle Atlantis, this is how they are describing what they are looking at from the Shuttle;
It’s a structure that’s definitely not rigid. Doesn’t look like anything I’ve ever seen on the outside of the Shuttle, that’s for sure […] [it] quickly moved to the nose of the orbiter, moving away at least 100 feet.
