For just over 500 days, the US Air Force’s mysterious X-37B OTV-3 robotic space plane has been casually orbiting the Earth. X-37B looks like the Space Shuttle, and launches into space on the back of a rocket like the Shuttle, but it’s actually fairly small at just under nine meters (30 feet) in length. What’s truly weird, though, is that I’ve now told you everything that we officially know about the X-37B — its payload, current mission, and combat capabilities are completely unknown. X-37B OTV-3, one of the world’s largest artificial satellites, has been up there for 500 days, shows no sign of coming down any time soon, and we have no idea what it’s doing or what it can do.
Many anti US members at the other board would go on and on how the Russian's didn't copy anything from the US, that the necessitated functions of aircraft dictate that the Russian aircraft look just like the American predecessors.
