I've flown on more aircraft than I can remember, but off the top of my head I can say:
Boeing 727, 737, 747, 757, 767, possibly 707 when I was very young
Douglas DC-9 and McDonnel Douglas and Boeing variants
Douglas DC-8, wonderful airplane
Douglas DC-10 and McDonnel Douglas variants
Lockheed L1011 Tristar, Lockheed's last hurrah in civil aviation and a nice plane for passengers
Airbus A320
Shorts 360
Beech Bonanza V-tail
at least one helicopter and some other turboprops I can't remember.
Personally piloted Cessna 150, Cessna 172
Lately I have come to despise flying on commercial airliners so much that I have no interest in keeping track of what sort of aircraft I'm on, so I may have missed an Airbus type or two. I know there are some others I am missing.
Until I sat down to type this I never realized just how much flying I have done in my life. I occasionally meet somebody who gets through college without ever having left the ground, but I was flying in the 1970s before I was even old enough to remember. Back then it was different. The service was good, there was a dress code, the stewardesses were hot, and the pilots used to take little kids into the cockpit and give us little toy airplanes.
Now flying just sucks and every minute in the air is spent waiting to get off and out of the airport. Civilization regresses, it seems.
