Giant UFOs

The UFO Hunters last night featured cases involving huge UFOs, largely over Europe. The cases followed a similar pattern. They involved pilots (military and civilian) as primary witnesses, the pilots were flying aircraft at the time of the sightings, the sightings included other witnesses (sometimes pilots in other planes), and the objects seen seemed to show up on radar, including ground radar. The incidents, therefore, seem to demand some explanation.

The weakest part of the cases might be the reported size of the UFO-- some were said to be a mile wide; another, miles long. Imagining why the aircraft attached to an expedition of an interstellar civilization would be so huge is extremely difficult. Almost certainly, space travel drives miniaturization of technology. Imagining such huge ships escaping the notice of all but a few people is also difficult. In one case, one huge disk seemed to have the capability of rendering itself invisible-- but then why show itself at all?

That said, huge ships seem to be sighted fairly regularly recently, including over America. If the dimensions are hundreds of feet, not miles, they could possibly be advanced, secret aircraft of our own making.
