3 in an airliner’s bathroom? Must have been pretty crowded in there, I would have locked them in and continued the flight to original destination....images of the POS’s soiling themselves like the putrid pig-dogs they are.
Instruct everyone to get back to their seat and fasten seat belts as severe turbulence is expected; and then make it happen. I wouldn't be surprised if a pilot could kill anyone who remained in a bathroom.
