It might have been a good idea not to let them onto the flight at all!
Sadly the British public think they have a God-given right to get tanked up and then get into an aircraft where they are not only a hazard to themselves but everyone else, especially if the aircraft ditches.
Maybe a suitable punishment for these w**kers would be a trip to the dunker - they might just realise that escaping from a submerged helicopter is not something you would want to do pissed.
