 Not all unexplainable sightings are of alien spacecraft. That's true. Some few are of government vehicles and some strange natural phenomena and all the rest of that. But don't believe the CIA when they said, oh, all those reports, you know, after the CIA was flying the U-2 and the SR-71, they were glad because people didn't know about those systems. Well, the number of sightings didn't go up when they started flying.
