On November 14, 2004, the USS Princeton, part of the USS Nimitz carrier strike group, noted an unknown craft on radar 100 miles off the coast of San Diego. For two weeks, the crew had been tracking objects that appeared at 80,000 feet and then plummeted to hover right above the Pacific Ocean.
When two FA-18F fighter jets from the aircraft carrier USS Nimitz arrived in the area, they first saw what appeared to be churning water, with a shadow of an oval shape underneath the surface. Then, in a few moments, a white Tic Tac-shaped object appeared above the water. It had no visible markings to indicate an engine, wings or windows, and infrared monitors didn't reveal any exhaust. Black Aces Commander David Fravor and Lt. Commander Jim Slaight of Strike Fighter Squadron 41 attempted to intercept the craft, but it accelerated away, re-appearing on radar 60 miles away. It moved three times the speed of sound and more than twice the speed of the fighter jets.
