Hey! Hey guys! I think I can see my Dacha in that picture of the moon!
In all seriousness though, this guy is obviously lying about his affiliation with NASA--in science, you deal with laws and theories. A law has been proven using a mathematical proof that works in every given instance without altering the language of the law. A theory (such as gravity and relativity, as well as a+b=c when a<b<c and a, b do not equal 0) has not been proven, therefore, is not always used.
If NASA only uses theories, completely disregarding scientific laws, it's a wonder NASA ever designed a space-shuttle at all. Whether it works or not is out of the question, the fact that they built anything as sexy and sleek as the space shuttle with only theories is a miracle.
And the fact that TomB has said that he not only watched the rover get built, but watched the launch and has been supervising the mission means he must be very, very, very high up. AND, working for the government myself this summer as an intern, I know that you're not allowed to publish any formal letter to any agency, organization, or individual without proper clearance from the higherups, and usually letters from one agency to another are presented by the agency's head.
So.....given those FACTS about how the government works, which you, being a high-ranking member of NASA yourself, how do you feel that you've broken protocol by posting a formal letter representing NASA, therefore affiliating NASA with the flatearthsociety.org forums? Unless you are, yourself, the head of NASA, in which case I would expect a congressional inquiry into your breach of very official protocol, having exposed NASA to the likes of Tom and his all-knowing braininess. He can kill you with his brain, you know?
