A 1950s flight experience would have been on something with piston engines and propellors, like a DC-6 or a Super Constellation. Noisy, turbulent, and not particularly safe by modern standards.
Today's airliners fly high where the air is smooth, they've gotten very good at avoiding turbulent weather, and there are automated damping systems. The barf bags are still there, but I've never seen anyone use one.
The cool thing about piston airliners, though, is the the engine start.
Today's high bypass jet engines also qualify as a turboprop.
The sound of a Merlin V12 coughing into life is just pure joy. My dad had the best job in the world flying P-51s (powered by Merlins). I hired a P-51 to do a flyby at his funeral. I only had to pay for the gas.
