In 2004, two United States fighter jets were sent to investigate a mysterious flying object that hovered off the coast of San Diego. Previously classified footage of the encounter was recently released by the U.S. Department of Defense, revealing Navy pilots reacting to the moving object, “My gosh… Look at that thing, dude… Look at that thing!” The footage was later investigated by a secret multimillion dollar program tasked with identifying and investigating unidentified flying objects (UFO), but The Pentagon admits the program ceased to exist in 2012.

During a routine training mission, Commander David Fravor and Lieutenant Commander Jim Slaight were asked to investigate the flying object. Commander Fravor told The New York Times that the object was big enough to churn the sea 50 feet below, “I have no idea what I saw... It accelerated like nothing I’ve ever seen.” It remains unclear what the object was.
