There are too many straight up and honest taggers at NASA for any coverup to work. Especially the older ex-military types near retirement. Some of them are having fits right now.
FYI, I understand that there was supposed to be an announcement Monday of who the next major shuttle contractor was supposed to be. I understsand that is on hold. It was supposed to be some contractor with a "hispanic name". I suppose that might be Hernandez Engineering or someone else.
