For me, flying and diving run neck and neck. I have to say that I have a different perspective on flying than most since I generally am the one in either the left or right seat. My best buddy is in the other one. When you push the throttle forward and the plane tries to move to the left off the runway and you give it rudder to stay straight. That is one of the best parts. The other parts of flying I like best I haven't done in a long while. Like being upside down. Now that's a blast. A hammerhead turn is pretty intense as well, you go straight up until the plane stops flying, kick hard rudder and opposite aileron, and then you are looking straight at the ground. It's a rush, but aerobatic airplanes are expensive. One day.....
Then again, flying on the airlines is like sitting in an uncomfortable chair in my living room.
Diving is like flying, but with out the wings and engine. It's like the way I used to dream about flying. I never get tired of diving and I don't get to dive enough either.
By the way, my best buddy, Donna, got her Air Transport Pilot rating last Friday. For those that don't know, that is the rating you have to have to sit in the left seat of an airliner. Anyone need an ex-Aero Professor for a commercial pilot? Donna is looking for a flying job.
