NASA has finished its probe of the sensational allegations about inebriated astronauts and found... Nothing. Surveying astronauts backthrough the 1990s, they found one incident where an astronaut unwisely mixed alcohol and a prescription drug in the pre-launch period, but that was it.
COMMENT: This makes sense. Whatever the lingering effects of fighter-pilot culture may be on the astronaut corps, it's important to remember that these people train and compete for years for every opportunity they get to fly in space. To jeopardize an oh-so-rare flight opportunity with prelaunch drinking would require an enormous lapse of judgment.
