Yeah, it’s a missile. It’s the world’s slowest SLBM ever that tracks a perfectly horizontal shadow and all the other pictures of the same routine flight on other days are all faked. Hell, if you go out there and see it yourself it’s fake too.
Go back through this thread and you'll find references to the materials used to do that.
Again, there was a flight on exactly that trajectory. Don't you imagine that if the flight wasn't there and didn't land that somebody would be out looking for the missing crew AND a gazillion UPS packages (as well as the USMail being carried in space available on contract.)
