China in the eighties.

A DC-3 (or similar?) loaded with tourist passengers starts up and is about to taxi.

Then the engines are shut down again.
The captain leaves the cockpit and adresses the passengers: « This plane ill! We take other plane! »

They all walk over to a DC-3 parked across the ramp. Engines started, and shut down again.

Captain adresses passengers again:
« This plane more ill! We take first plane! »
