Brilliant. Only in a bureaucracy like NASA do you order people to sit on their hands for two years every time there is a problem.
Did it ever occur to those morons that we should press on and have a shuttle ready to launch in case of problems on the ISS? Hell, if a generic problem is found, they can always destack and fix it.
If the flights were unmanned, they'd shrug with disappointment, but move on quickly. This will be Nasa's third prolonged period of mourning. Think how much farther we'd be if we took the focus off manned flight for unmanned.
