Here are five compelling photographs, and the story behind each. This video will take only 6 minutes of your time. The one I find the most compelling is the first one, taken during the 'Belgium Wave" which is explained in the video. Of the 130,000 witnesses, 2600 persons filed reports on what they saw, and the description was pretty much the same with all of them. There is a video of this black triangle, named the TR3b, allegedly is an American creation, with black ops money. It's propulsion system is described by Edgar Fouché, and American Air Force avionics specialist
The triangle UFOs might be one of ours. At least most of them. The orb UFOs are also one of ours, at least in my experience. The other shapes like flying saucers are probably mostly aliens.
