Well I think that those pilots were actually quite responsible guys - I mean it would be very silly and dangerous to drive a car while drunk - especially with all those nasty taxi drivers out there!
I mean when they are at work pilots are pretty supernumery anyhow....
I mean the Ops dept and their computers do all the planning, the nice dispatcher type person does all their weight calculations for them, the hosties count the pax and give them the safety spiel, ATC tell them which way to steer and if they are in danger of bumping into anything or anyone else who might be a bit tipsy up there.
The nice shiny airplane can fly them all the way to where they want to go and even land itself at the other end. By which time they should have sobered up enough to manage to steer the thing to the gate, (assuming they haven't spent too much time in the bar enroute) - even that doesn't have to be too accurate as the bridge thingy has wheels and can come to the airplane if need be.
Then the nice man in the crew bus can take them straight to the bar and the lose (wo)men and they can start getting ready for the homeward sector.
So by my reckoning as long as the guys can manage to keep the thing going reasonable straight down the runway, and thats not too important after all its about 200 ft wide, til about 150 knots and get it in the air everything will be just fine.
