A couple or three things come to mind.
When will the first pilot go to jail for being tired? Three people in the UK have now been jailed for causing an accident wile driving tired; the last one it seems was of perfect character before an unexplained excursion across the road which got him a year inside.
The assumption that a small amount of booze is OK is alway a little risky. It is the small amount that makes us think that a bit more will not matter too much, then just a drop...etc. etc.. This has always led me to believe that any crime that may be committed, is at the early stage of a drinking session. The planning should be as meticulous as fuel calculations, but then in a perfect world I would not be trying to sleep in the middle of a noisy town at noon, with the A/C out and a road drill outside.
Pilots have probably always resorted to alcohol to help with the difficult lifestyle. If we are to set new standards in sobriety, what will be done to aid proper sleep requirements?
