The Nimitz Tic Tac

Navy pilots, radar, infrared: a white object dropping 80,000 feet in a second.

Four aviators, two aircraft, radar operators on the Princeton tracking objects dropping from 80,000 feet to the deck in under a second, and an infrared tape the Pentagon later confirmed as genuine. Commander Fravor's summary to Congress was the plainest sentence in UFO history: 'It was not of this world.' The object, whatever it was, knew the classified rendezvous point. That detail never gets explained.
