Please see Spacewatch,Spacefaring by Bureaucrats over a http://www.spacedaily.com A terrific read on Nasa's biggest problem with waste,paperwork,rules,spending programs,redesign,etc. its amazing you could get anything out that flys through their process but that has been their problem. Lots of designs on paperwork and nothing real. Great article that explains some very real problems at NASA. (edit) Companies like Scaled Composites wont even bid just because of a mountain of never ending paperwork that is part of the requirement for the new Shuttle replacement.
