Why Did You Turn Off the Plane's Engine?

As a pilot I like to see the humorous side of flying a light aircraft.

Here's a joke about a student pilot who was sent on the first solo flight without the instructor.

Instructor to student pilot (who just crashed the aircraft): "What happened, you were doing so well on your first solo?"

Student pilot to instructor: "Well, I was doing fine at a thousand feet so I thought I'd climb a little higher. Then I climbed to two thousand feet and that felt OK too. But then as I was climbing higher and higher to three thousand feet, it was getting colder and colder, so I turned off the big fan at the front!"

Here's the big fan at the front - the propeller!
