Those NW guys who flew from Fargo to MSP all went to Federal Prisons for a full year. The Captain was sent to the one in Atlanta, where lots of really bad people reside (well...just nice people who did some bad things). So bad that he seriously considered suicide several times. And he was reportedly no wimp. Upon arrival, certain authorities extrapolated the crew's breathalyzer results, guessing how much it would have registered before the flight. The judge was "ALLEGEDLY" prejudiced, being quite familiar with a railroad accident in which the Engineer had a drug in his system, and wanted to find anyone suspected of being under the influence of whatever, especially in a public transportation industry.
The aircraft was not involved in any actual incident, otherwise, but an FAA "representative" had talked to the Captain just before the flight and mentioned that there was some sort of concern about or problem with the crew. The Captain never told the First Officer or Flight Engineer about the conversation. The Captain later earned all of his ratings back from scratch and became an instructor. The other pilots were never welcomed back because they had never confessed to a drinking problem-
sounds kind of like the "Peoples' Republic" of China mentality...? I read all of this somewhere.
