I should add that I used to work at Tucson Int'l Airport for 11 years. I loved watching the planes all those years. As I was out and about in the city, I used to be able to name the airline by seeing the plane and it's colors in the far distant. I got to fly in a Continental plane while a film crew was shooting for a commercial. It took off, circled south, headed back to the airport, touched down and took off right away again. It did this for like an hour. I love flying so that was a free hour carnival ride for me! lol
