Also, being an aeronautics/aerospace oriented individual, I have been familiar with many aircraft that are easily UFO material until, that is, they emerge from the 'black world'...F-117, and its predecessor, the Have Blue aircraft, when seen in profile, look like a flying wedge, and from above/below, they look like giant flying arrowheads. And others, such as the Bird of Prey revealed last year, resembling somewhat a Klingon vessel in small scale, and Tacit Blue, an arcraft that bore a strong resemblance to a flying butterdish. And don't forget Bombardier's drone, I believe the model is CL-327, which looks loke a large grey peanut, or hourglass.
UFO'f have become boring because so many have later been revealed as our own 'black world' projects, and most, if not all others, only have 'blurry dot of light' film to back up a sighting. GLORY!! Government's don't have to discredit them, UFO-ologists are doing it to themselves.
