Maybe until mid 1995. All the passengers carry their seats out onto the tarmac, placing the chairs in the outline of a plane. They all sit down, flap their arms and make jet swooshing sounds as if they are flying. 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 all gather in the hangar, watching hundreds of technicians check the flight systems on this immense, luxury aircraft. This plane has at least 10 engines and seats over 1,000 passengers. Bigger models in the fleet can have more engines than anyone can count and fly even more passengers than there are on Earth. It is claimed to cost less per passenger mile to operate these humongous planes than any other aircraft ever built, unless you personally have to pay for the ticket.
