An airliner was making its way from New York to San Francisco. Midway across the country, one of the engines caught fire.

The captain came on the intercom and calmly reassured the passengers,

> “Don’t worry. The fire will be out soon. This aircraft can fly just fine with three engines.”

Not long after, a second engine failed. Again the captain announced,

> “Don’t worry. We can fly safely on two engines.”

Then a third engine flamed out.

This time there was silence.

Finally the captain stepped into the cabin with a parachute strapped to his back.

Opening the exit door, he called out,

> “Don’t panic. I’m going for help!”
