I definitely flew TWA, and as an aside ... I think the last TWA livery was the most beautiful paint scheme ever.
Being a wannabe, even while serving as an Army grunt in Germany in the late 1980s, I used to read about the aircraft I went back and forth on. If memory serves, I think this was what I rode from Frankfurt/Rein Mein...
Pan Am - Airbus 300(?)
TWA - L1011
Someone? - DC10
Lufthansa - 747 (First 747 ... and last.)
World Airways' L1011s back and forth from the NTC to Fort Hood, too.
I also seem to remember Delta in there somewhere, but I don't remember what they used to FRG back then. L1011s?
I used to wander up front each trip and take a gander at the flight deck. Back then I had only a few hours here and there in C150s, and I thought after I got out of the Army and finished school I'd finish my ratings and try to instruct part-time as I built a career in Industrial Engineering. It hasn't quite worked out that way, but I haven't given up the dream. I could happily fly a King Air or a Citation as long as my medical held out. I have given up on ever getting into an airliner.
