Passengers on a Ryanair flight from Fez, Morocco, to Beauvais, France, refused to depart the aircraft after a weather delay forced the plane to land in Liege, Belgium. After landing, passengers were asked to disembark and board buses for the 3-hour ride back to the Paris area. No dice.
Instead, they staged a sit-in, refusing to get off the plane for 4 hours demanding they be flown back to France. At one point, flight attendants locked the toilet doors, turned off the lights, and walked off the aircraft with the pilots in tow. (If you were wondering whether the French will strike over anything, this would answer that question in the affirmative.)
Airport officials went to the plane and managed to convince the passengers (with some help from local police) to sit in the airport lounge, enjoy some free food and drink, then take free buses back to France. At 3:30am.
