This is another mass sighting of silent low flying triangular craft that occurred from 1989-1990. The documentation of this event includes thousands of witnesses, police reports, and military reports. It ranks with the Phoenix lights as one of the most credible instances of UFO sightings in history. You can read the Wikipedia article here. The skeptics' replies? A mass hallucination. Overactive imagination. Or helicopters that couldn't be heard because of running car engines or the wind. lol! http://en.wikipedia.org/wiki/Belgian_UFO_wave Please Register or Log in to view the hidden image!
