Well, after looking at the very informative site on the crash that another member had posted, I believe it was a plane that crashed there. The photos and the information convinced me.
As to the moon landing, the reason there was no 'dust' floating around is because there is no air to keep it suspended, and because any dust there would have been blasted away by the landing rockets on the lander as it came in. Any particles hit by the rocket blast would be moved at very high speeds, by the velocity of the rocket exhaust, faster than most bullets. The rocket flame we see in the air looks different in a vacuum, a point they often forget in cheap space movies of the 50s. Good point about the Russians, they would have loved to point out our failings. How about the other space missions, were they filmed at home too?
I'm sure this isn't going to convince any doubters, but I had to say it. At least we can still discuss these topics in a free manner.
