I blonbe got a free lesson to a helicopter and when she got it she radioed in and said,"what do I do". The people said fle to 10,00 feet,so she did.Then she said "where do I go now".They said a go to 20,000 feet. Then they herd a loud crash and the blonde was bairly alive a they asid "What happened" and the blonde sais "It got too cold so i turned the big fan off".
