A fighter jet pilot who was one of the first to witness the now-famous Nimitz UFO believes it is “highly possible” the US government is in possession of alien technology.

Commander David Fravor was one of two United States Air Force (USAF) pilots to first encounter the “tic-tac” craft off the coast of San Diego in 2004.

The sighting would go on to become one of the most famous encounters ever caught on camera, with the Pentagon publicly acknowledging they had no idea what the object was.

While Fravor believes the UFO was not of this Earth, he is certain similar alien technology is being held by governments across the world.
