SUMMARY 15.02.2011 

An old lady wanted to fly t Denver. But before boarding she wanted the pilot to guarantee her he wouldn't exceed 4000 feed in altitude. After a lot of argues with the airport clerks, they decided to call the pilot. The woman told him his doctor had told her she wouldbe liable to have troubles if she went over 4000 feet. The pilot explained her that was impossible, because Denver was over 5000 feet on the sea level, too. The woman answered she would cancel her flight because she had always thought Denver was on the ground.
