In the hangar, investigators who enter the ship find it to have been manned by a crew of two, both now dead. (During the collision with the satellite, some chemicals were released producing a short-lived toxic gas). As technicians and scientists work, they discover several things: a woman in some sort of stasis, who later wakes up screaming; symbols on the control panels match those used by ancient Earth civilizations; the ship's computer reveals extensive surveillance footage of power plants, military bases, industrial plants and major cities worldwide. Upon autopsy, the aliens' physiology shows they and humans underwent a similar evolutionary process. A scientist deduces that the ship could not have reached Earth on its own; that it must have launched from a larger, faster and more long-ranged mother ship.
