Robert explains the mystery behind the UFO sighting made by the USS Nimitz. In November of 2004, the USS Nimitz along with the USS Princeton monitored clear radar traces of UFOs over the Pacific Ocean off the coast of San Diego. 2 F-18 Super Hornet jets made visual confirmation of a large floating Tic Tac structure and when approached flew over 60 miles away in a matter of seconds. No explanation of what the craft was or where it came from have been reported.
