HBO goes over the history of UFO Disclosure. With Disclosure seeming to approach, it seems appropriate to begin reviewing the history of sightings and cover-ups.
As a side note, engineers at the company I worked for back in the mid-1990s, Hughes Aircraft, acknowledged to me that Hughes had received from the military the silicon chip, taken from the Roswell spacecraft, which served as the back-engineered heart of what became our computer.
The Internet also derives from galactic technologies, as do Kevlar, Teflon, fiberoptics, stealth technology, etc.
