I have managed to get on a plane so drunk once I thought we were taking off as we landed. I could never be a rowdy drunk, though. Alcohol makes me sleepy
A bit ridiculous offering breathalyser tests and then allowing people to drink alcohol.
Imagine being breathalysed by a traffic policeman and then being offered a congratulatory glass of whisky for not being over the limit
However I would agree with issuing a tranquilizer gun so they can shoot these ar53h0les, sedate and strap them in and gag them to avoid inconveniencing the other passengers.
