The engine on the airplane sputters to a stop.
The captain comes over the intercom.

“Attention passengers we’ve had a minor problem with one of our engines, but we have three more and will only be a little late arriving at our destination”.

A short while later another engine grinds to a halt with a small train of smoke coming from it. Again the captain comes on the intercom.

“Attention passengers We are continuing to have minor technical issues with our engines but we have two fully functional engines and will now be an hour late to our destination.”

Passengers begin to grumble, but hope for the best.

The third engine also stops and very quickly the captain comes over the intercom.

Attention passengers, we are down to one engine and are looking for an open runway for maintenance”
One of the passengers stands up and says, “Thank God that fourth engine didn’t go otherwise we would be stuck up here all day”.
