Well, one of them, anyway.
A few years ago, I was running late to my evening computer repair class at a local junior college, and I saw this thing hovering in the air, essentially motionless, yet turning ever so slightly.
It was about 500 yards away from me, and I could see details clearly. Hullo, 20/10 vision here. It looked like it was suspended by a cable from a large crane, except there was no cable, no crane, no wires near it...it was just..there. Hanging. In mid-air.
The sun was still up, not to set for another half hour or so, and it was bathed in sunlight, as well as being lit from the inside.My impression of it was that it was a cross of Doctor Who's Tardis, and a Chinese temple. It had a red roof that looked exactly like a pagoda. Red, with four corners.
It looked as if the box part had been painted decoratively. And the 'roof' was copied on the bottom of it. I'd guess that it was about fifteen feet high, with each side being approximately five to six feet across. The road I was on curved around the farmhouse, so I lost sight of it behind the trees and the barn, and then I got a perfect view of it after I passed.
I wish now I had pulled off the road and parked, but I was worried about getting to class, so I kept on going. But that is a true and accurate accounting of what I saw with my own eyes, and when I saw the pic in the British press, I must confess, it gave me quite a jolt.
