Well, I'll certainly agree with a lot of your choices, but not in your order (different strokes for different folks). In my opinion - for purely beautiful lines - the all-time sexiest airliner is the Lockheed Constellation. They even sound wonderful with those four big radial engines!
What was the power plant on a Connie?
I fell in love with the sound of radial engines when our small town got one flight a day by a National Airlines Lockheed Lodestar. I would ride my bike down to a spot that it often came over as it climbed out, and the sound from those twin radials 2 or 3 hundred feet up with every knob pushed or pulled was music to my ears.
OK, enough reminiscing for one day. When I get started on old airplanes I never know when to quit, so I now quit.
I've seen her at Oshkosh a few times I went...:)
