P.S. #3 assumes a large number of people are aware of what really
happened out there. I don't believe that at all. There were a few,
select individuals (Borman being one of them) who knew exactly what
happened and participated in the lie. The rest just have their
suspicions. So, we're not talking about thousands of people
in-the-know. The Air Force and NASA would have kept it to "Need to
Know" only.
