When I look at the pictures of the planes, I think it is simply amazing how drastic of a change the jet engine made to flying. For example; when I look at the really old airplanes, I remember back when I was in training to be a pilot and some of the instructors who flew during WWII talked about when flying only centered around what we call using a stick and rudder.
Today, with the addition of the jet engine that added thrust to flying, also added flaps and slats, along with ailerons or speed brakes. Pilots today have to be so much more educated with not just flying, but it also helps to be a weatherman, as well. Automation and Fly By Wire Technology has added an incredible amount of safety to flying.
