While SETI didn't find aliens that night, they did do NASA a huge favor by finding the errant satellite, which was later recovered. And SETI is still looking for those alien signals. Let's think about this, guys. The night sky does not exist only over the United States. Any signals from space would be picked up by telescopes all over the world at once.
Radio telescopes exist all over the world, and are run by foreign governments.
With politics the way it is, I'm sure some country or another would refuse to be part of a global conspiracy, or at least wouldn't have the total control over its citizens to stop any news leaks. The thing I said earlier about aliens abducting only Americans isn't strictly true. I did some research, and I found concentrations of alien abduction claims in the U. S., Britain and, strangely, Queensland, Australia. But on the whole, alien abductions and UFO sightings are mostly limited to wealthy, European-based cultures. Aliens just don't like to visit places where people haven't seen Close Encounters of the Third Kind or the X-Files.
