Joe was a pilot and decided he wanted to learn how to fly a helicopter.
He went to the airport, but the only available helicopter was a solo one.
Mark, the Instructor, figured he could let Joe go up alone since he was already a pilot for small planes and he could instruct him by radio.
So up Joe went.
He reached 1,000 feet and everything was going smoothly.
He reached 2,000 feet.
Joe and Mark kept in communication via radio.
Everything was running smoothly.
At 3,000 feet the helicopter suddenly started to plummet!
It skimmed the top of some trees and crash landed in the woods.
Mark jumped into his jeep and rushed out to see if Joe was okay.
As Mark reached the edge of the woods, Joe was walking out.
"What happened?" the Mark asked. "Twas all goin fine til you reached 3000 feet. What happened then?"
"Well," began Joe, "I got cold. So I turned off the ceiling fan."
