Accident investigators were profoundly affected by the experience as well.
Albert Wheelon, the chief executive of an aerospace contractor that did
business with NASA, said he was surprised by the "cover-up and cynicism"
he discovered at the space agency.

"I thought I had better be a little more careful about dealing with NASA
in the future," Wheelon, a member of the Challenger investigation
commission and former president of Hughes Aircraft, said. "It seemed to me
they had a very different value structure than the military or commercial
industry. It was the kind of thing you would expect from Enron or WorldCom."
