>>509367787 (OP)UFOs are real but 99% of the lore is all fake disinfo.
Early crashed like Magenta, Italy and Cape Girardeau and the later crashes at around Roswell and Aztec were real. Los Alamos had a special radar the disrupted the electromagnetic fields in and around the UFOs skin, so they slammed into the ground going 15,000 mph.
A deal was made and the Aliens gifted us a UFO at Kingsman Arizona, which was brought to Area 51, but is now at Helendale, CA. .
That UFO skill exists and was given to Lockheed martin (who doesn't want it anymore) and tried to give it to Bigelow aerospace.
That UFO looked like pic related. It was called "The Hopeless Diamond" and it gave us the angles to create stealth technology. The angles in mathematics are actually so complicated (wave dynamics being the hardest known math) that no man could ever figure it out, until we got the UFO. The math around the F-117 has been described as a miracle.
We can't reverse engineer the UFOs themselves because we can't make the layers of bismuth and magnesium in the UFO skin. But we did invent Nitinol a Titanium alloy discovered from the Roswell crash that was studied at Wright Patterson AFB.
