I have a feeling those UFO's spotted by Navy Pilots are unmanned aircraft made for the Air Force. I think they are testing them over water out of sight. The navy pilots do not know about the aircraft. They don't know it but they are part of the testing. I remember sitting in a history class in high school back in 1984 and we were talking about an invisible aircraft that crashed. It was a stealth aircraft that we learned several years later.I have a buddy that works for Raytheon and without giving details he says the Air Force and Navy are working on technology that would blow your mind. He talks about the 6th Gen fighter and how it will have the ability to be operated with or without a pilot. For instance it can operate unmanned as a bomber escort or wingman to another fighter and if attacked it will be able to go on the defense autonomously. Without a pilot to black out there's no telling how many wild maneuvers it will be able to perform.
