While most people will scream this is X-Files fantasy I could be convinced as there was so much for the americans to lose at the time. They had (in the form of Kennedy) promised they would walk on the moon by the end of the decade and they just scraped in, and the lose of pride in the country would have been enormous had the russians got there first. Added to this that for years photographics experts have been saying that the lighting is all skew-whiff with shadows in the wrong places and such like then the evidence keeps climbing and while I believe unlike some that we have been there at some point after the first landing I do have my suspicions that the first couple may have been faked.
