The control panels in a UFO cockpit are next to missing since they control the ship mostly with their thought waves. Their thought waves are pretty powerful and a bit disturbing when they impact a human. Did you ever have one of those moments when you walked upstairs/downstairs etc to get something and then had no idea what you were going to get? If so, you were most likely hit by the stray thoughts of an alien.
