At NASA, once again, the problem is its culture - a habit of dismissing the concerns of knowledgeable underlings. Four years ago, it involved higher-ups ignoring engineers who feared possible catastrophic damage to the shuttle Columbia. The engineers were right.
This time, it's NASA doctors and even astronauts getting the brushoff when voicing worries that some astronauts have drunk too much alcohol before flying.
"I think things have changed, but some things remain the same," said Douglas Osheroff, a Nobel Prize-winning physicist who investigated the Columbia disaster in 2003.
An independent health panel disclosed Friday that, at least twice, astronauts were cleared to fly despite warnings from flight surgeons and other astronauts about their heavy drinking. One intoxicated astronaut flew into orbit on a Russian spacecraft; the other ended up with a shuttle launch delay for mechanical reasons but later tried to take off in a training jet while still under the influence.
