So far, it seems to be the real thing. The sky in this frame grab was cleaned up (being several generations beyond the original), but the craft is untouched, other than some contrast adjustment.
It was recently reported by Whitley Strieber that a woman was located who had
stood directly under the ship (which appears to be about 10 to 15 meters in
diameter - about 40 feet). She said she experienced a feeling of being pressed
down..presumably from the invisible gravity beam that UFOs are assumed to be
utilizing for their amazing levitation, without noise or air disturbance.
