Something you'd think NASA would be aware of when some random doofus calls them and claims to be one, but maybe commercial airline pilot Jerry Alan Whittredge was just very convincing.
After claiming to be a CIA agent with the Congressional Medal of Honor AND a member of the next shuttle mission, Whittredge convinced the folks at the Space Center in Alabama to give him an exclusive tour.
To be fair, he was wearing an appropriate costume.
Come on, NASA has rocket science and crap to work on! You can't expect these highly educated people, some of the most intelligent on Earth, to check resumes before handing over classified information about the shuttle's propulsion system to some schmuck they don't know. And while they're at it, you can't expect them to NOT let an unqualified stranger sit at Mission Control during a shuttle mission.
