Looks fake to me too, but is exactly what I want to build for halloween, though I will be making only half a disc and putting a spacey tape and fog
machine in it. I will also carve an alien arm and hook it up to a windshield wiper motor so I can remotely have it jiggle, or wave when kids come
around.
Its a radar array dish, look to the lower right side of the "disc" and you will see what looks like a supporting strut similar to a hydraulic
cylinder.
I think it is fake, if it had accually craqshed, there would have been a crater, and the craft would be in farther. Also, given the size, less then
half of the craft was in the ground. I think it would need 1/3 2 1/2 of it in the ground to stnd verticle like that. ITS FAKE!
