My father told me a story of seeing C-47s flying back to England in WWII with an engine dead and smoking and holes in the wings that made it a wonder they could fly with both engines. I had the privilege of some left seat time in one while in ROTC in 1970. Talk about a sedate flier. When turning, one only had to bank in the direction of the turn and hold the nose up. The rudder didn't even come into play on a gentle turn. It was as if the plane knew what to do.
I got a good look at what Americans complain about. I had to fly from Oklahoma to the Yukon on various Boeing 737s. While on the U.S. carriers, there was little service and my knees were jammed into the seat in front of me. On the little Canadian carriers I had plenty of legroom and service I'd seen only in first class on the American ones. The question becomes do the customers serve the airline, or do the airlines serve the customers?
Obviously, one doesn't understand the concept of a job that a person enjoys doing and finds rewarding enough to work far beyond normal years. I applaud Mrs. DiSalvo.
