Howard Hughes says its more like 5%.
Howard actually said...
considerably less than 5%!
Now I can only go on my career, but of the people I have met and flown with, I would say that it is more than 0.001%, but considerably less than 5%! I wouldn't like to put an exact figure on it...
Now I am not saying that people turn up to work drunk, that number would be almost miniscule. But there are a lot that push the boundaries, ie: push the minimum time between drinking and working! I consider this in itself a serious offence, one that breaks the duty of care that we owe our passengers!
Am I without fault? NO!
Do I have personally imposed limits that are far more restrictive than any regulatory or company imposed limits? YES!
