'Northrop Grumman' aerospace defense contractor cofounder John Grumman on UFOs.
Quote:• "The propulsion of these UFOs is unique - their ability to hover; their ability to accelerate very rapidly; their ability to move at very high speeds - very much higher than we have achieved with our supersonic aircraft - all of these things, and particularly interesting without sonic booms and the things we don't like about our supersonic aircraft, all of these things indicate a type of propulsion which is unique - it's different than we know anything about and it would be of tremendous value if we could develop it and use it."
