STS-37 UFO




"During the STS-37 flight on April 1991, the shuttle while on the day side of earth, there appeared a round UFO outside the viewing window.  As it arrives on the scene, the shuttle rocks back and forth as if the UFO's magnetic field affects the shuttle.  The UFO flies left to right, changes course to left and then hovers for about 30 seconds like it was observing the shuttle then bobbles a little bit for a couple of seconds.  Then the action is repeated in closeup mode."
