There was an interesting show on TV here last week about UFOs. It examined the various possible reasons for the rash of sightings years ago, including -- as you would expect -- classic cases such as Roswell in 1947 and the saucers over Washington, D.C. in 1952.
It looked at the work of German scientists who worked at the various Nevada and New Mexico test sites at the end of WWII, and the files of what were then secret government projects, quite a few of which could certainly have been taken for alien spacecraft by many people at the time.
Right at the end of the show, they visited a guy in Seattle who was conducting anti-gravity experiments in his garage. He had constructed a "saucer" which seemed to consist primarily of some sort of aluminized film (mylar perhaps, or something similar) above which and supported on 2- or 3-inch high insulators ran a wire around the periphery.
We didn't hear much about the power source operating below, but there was brief mention of induced high voltages and whether it was an ion wind of some kind which was providing the lift. It was certainly impressive.
