If I was an eye witness and I had seen there was positively no plane (and I knew that all the other people around me must have seen the same thing) then I'd want to get in touch with others in the same position as me for mutual support. I think the internet would be great for that. And I might find that, although everyone else tells me I'm crazy, there are a few people called "no-planers" who would believe me, and who weren't afraid to speak out. I'd definitely seek those guys out and make sure they knew they were on the right track.
So, Anders, I guess you must have had literally hundreds of emails of support from eye-witnesses, nervous of coming forward themselves.
No?
Oh, well.
