Object moving at incredible speeds. makes u turn in sky within seconds. i've been aircraft mechanics for 10 years at this point. worked on civilian and military helicopters as well as commercial and civilian airplanes. the noises you hear are apache helicopter taxiing by at military base. the rotor is in the video of a parked apache helicopter. the man at the end was a co-worker. like i said this was caught on accident. once the video is slowed down and blown up on my 65 inch tv there is a lot more going on than just the disc flying across the screen. pretty crazy how fast it's moving. no way you would see this with the naked eye
