HOUSTON, Texas (AP) -- NASA engineers are checking into a baffling sight of a mystery object below the shuttle that mission control spotted at about 2:45 a.m EDT Tuesday with a video camera in the shuttle's cargo bay.
The object, which circled the Earth in the same orbit as the shuttle and is of undetermined size, probably came out of the shuttle's cargo bay because some jets had just been fired, shaking the orbiter, NASA spokesman Doug Peterson said.

seems that the "object" in question is NOT a ufo as we have come to think of it as alien - instead it is a ufo of something that may have been shaken loose when the doors were open in the shuttle's cargo bay
