pickens writes "Florida today reports that as NASA marches toward its final two shuttle flights, the safety of the crew rests with workers who know every bolt they turn, every heat-shield tile they inspect, brings them that much closer to the unemployment line in April 2011 raising concerns that people might jump ship early if other job opportunities open up. 'We've been most concerned about maintaining and sustaining the knowledge necessary to safely conduct mission operations,' says Retired Navy Vice Adm. Joseph Dyer. But shuttle work force surveys show a fierce loyalty and a dedication to sticking it out as long term employees want to be there when the last shuttle touches down. 'They love being part of NASA and what NASA does, and they love being part of the space shuttle program. And they want to be a part of it as long as we're doing the kinds of things that we're doing,' says LeRoy Cain, NASA's deputy shuttle program manager."
