HERE IS AN AIRCRAFT we can not identify, and by definition it is a UFO. It was observed in the area around "Area 51". We can only wonder. I doubt it is "ours", because it's construction does not follow the principles of Aerodynamics, besides it was silent. The only thing that resembles "ours", are the "rocket shaped" rods at the tip of the wings. BUT - it could be absolutely anything, including a test Hologram.
