Passenger is a customer of Airline. He has boarded one of Airline's planes late one evening on a flight that is expected to be about three hours. However, shortly after takeoff, the flight is diverted to an unexpected airport due to bad weather. When the plane arrives at its unexpected location, Passenger and his fellow cabinmates are not permitted to disembark from the airplane. Instead, the passengers are told that, given the late hour, they must stay on the plane because there are insufficient security personnel at their arrival airport to handle the large number of passengers. They are also told that it is a violation of federal law to open any of the marked emergency exits under these circumstances. The passengers wait on the airplane overnight for more than ten hours, during which time they are provided with just one beverage, no food, and are subjected to very unpleasant odors because the airplane's lavatories became out of order and began overflowing shortly after arriving at the unexpected airport. False imprisonment? Please give a RIGOROUS explanation.
