Maybe until mid-1995. Then they all sit down and make a wooshing sound like they're flying. All passenger bring a piece of the aeroplane and a box of tools with them to the airport. They gather on the tarmac, arguing constantly about what kind of plane they want to build and how to put it together. Eventually, the passengers split into groups and build several different aircraft, but give them all the same name.
Some passengers actually reach their destinations.
All passengers believe they got there. The passengers gather and shout for an airplane, then wait and wait and wait. A bunch of people come, each carrying one piece of the plane with them. These people all go out onto the runway and put the plane together piece by piece, arguing constantly about what kind of plane they are building. The plane finally takes off, leaving the passengers on the ground waiting and waiting and waiting.
