Everyone marches out onto the runway, says the password in unison, and forms the outline of an airplane. Then they all sit down and make a whooshing sound like they're flying.
Everyone brings one piece of the plane with them when they come to the airport. They all go out on the runway and put the plane together piece by piece, arguing constantly about what kind of plane they're building.
A small private airline with lots of onflight movies, snacks and other luxuries to keep the passengers happy. Unfortunately, after takeoff, the plane has nowhere to go and keeps flying in circles until it runs out of fuel and crashes. The few surviving passengers, unable to comprehend the magnitude of the disaster, ardently vow to keep flying the same plane once it's put back together.
