A blonde was taking on-line flying lessons. It was time for her to take her flying test. The instructor told her to go up 1000 feet and radio back. Then he instructed her to go up to 2000 feet and radio back. Again, he instructed her to go up to 3000 feet and radio back.
She took the helicopter up to 1000 feet and radioed back. She was doing well, so she went on up to 2000 feet and radioed back. Still doing well, she went on up to 3000 feet. This time she crashed in the field.
The instructor asked her what happened when he got to her. The blonde said, "When I got to 3000 feet, I got cold so I turned off the big fan."
