My plane had left the gate at O'Hare Airport in Chicago - and I thought we were on our way. Wrong. First, they routed us across the backside of the airport - I think it was in Wisconsin. Then, after a slow, meandering tour of that huge airport, we finally ended up in a long line of aircraft waiting to take of. Well, after a while, I got a little impatient. That's okay. What's important is that the pilot not getting impatient. We don't want him to go until the tower says it's okay. He knows you don't take off until you've gotten clearance from the tower - no matter how long you have to wait.
