Aviation Week has reported that an independent panel found that at least two astronauts that were drunk before flying. It was also stated that other astronauts and flight medics warned that they were so drunk as to pose a flight-safety risk.
The 12-hour "bottle-to-throttle" rule is standard NASA policy for flight crew members. No astronaut was named by the special investigative panel.
NASA said it plans to release information by an outside committee and an internal panel looking into the astronaut health in a few days.
