Blunders do happen, but if you are a member of the general public and not NASA, you must assume that there is something else going on.
I feel that in such cases it is the obligation of the government to prove that JFK died in a car crash, and the public's to prove that Princess Diana was shot!
As for the moon landing, who cares, all this hype and conpiracy theories come from an era where over-paranoid american agents and soviet communist drones were trying to outnuke each other, with some hippies thrown in to mix things up .
The age of private space flight is upon us, if people are so worried about the moon landing they might as well form an organization, buy a cheap 1990's rocket and send it up there
Edit: OMG!
You mean the abomination that was the 'Special Edition'? With crappy, last-millenium digital effects that ruin the whole feeling?
Note a VERY interesting parallel here: After years of protests, George Lucas decides to let the fans view the original films on DVD, but claims that he lost the original tapes, so they have to be remastered from lower quality laserdiscs - this way the 'special' editions will still look better.
Now that's what i call a clumsy cover-up!
