UFO in U.S. Air Force Commercial,
Unknown Date, Daytime
The UFO shows up just before the bomb explodes, 21 seconds into the video. It flies unbelievably fast to the right. Freeze-frame it to see the shape of the UFO, which seems to be cylindrical shaped.
This footage comes most likely from the Pentagon Channel, which we have in Europe, too.
