@Radgirl: spot on !
When I started flying I became a teetotaler and have refrained from drugs all my life. (boring person, me...)
Never the less I am annoyed by the distrust - now imagine the society would do this with all the drivers out there - would that be accepted ? What happens if you are "caught" by broken equipment - what does that to your work relationship even when cleared afterwards ? Will such entries disappear or not ? Like the SAFA DB entries that you CAN`T challenge even when everyone agrees the inspector was wrong ?
The trigger was the murderer Lubitz and his dirty handiwork. Now this fellow was a known nut - does anyone think, a once marked "loony" pilot would ever get his ticket back after this one ? The logical consequence is going below the radar.
