We are not North Korea. The worst that would happen would be the Administrator would be fired (under Clinton). I believe GWB would listen to the Administrator of NASA if he said it was unsafe. With a Republican Congress and/or President for much of the last 25 years, NASA had every opportunity to do what was necessary. Republicans would not hang an Administrator for questioning safety.
