A MAN was taking helicopter lessons and, despite not exactly being the sharpest knife in the drawer, was finally ready to attempt his first solo flight. His instructor told him to radio him every 1000 feet to make sure everything was okay.
At 1000 feet he radioed the instructor: “Everything is fine.”
At 2000 feet, he again radioed the instructor: “Everything is fine, just getting a little cold.”
But before he reached 3000 feet, the helicopter plummeted out of the sky and crashed into the ground. Miraculously, the man was fine.
The instructor ran to him and asked: “What happened?”
The not-very-bright man replied: “I told you it was getting cold, so I shut off the giant fan.”
