Something that always comes to my mind-
AFAIK, there has been no instance of an intoxicated pilot causing death or injury flying an airliner, yet being caught over the limit (though BELOW the limit for driving) seems to carry an automatic, lengthy jail term.
We KNOW that MANY lives are lost each year to drunk drivers,yet it takes multiple offences before any DUI driver is jailed, and then often for short periods.
Showing up intoxicated to fly is obviously a heinously irresponsible act. I would expect anyone doing this to be sacked, face licence loss or lengthy suspension, and face large civil fines, but why is it an automatic jail sentence for something we have no evidence has ever actually hurt anyone?
