Never got to fly the Connie , but did get a few years on the DC 6.
I will never forget the wonderful low rumble of 4 big radials when the props were pulled back to low cruise.
Since the airplane I was on was operated without a FE, I was introduced to the challenges of interpreting the cathode ray tube engine analyzer. The good news is that in a subsequent job interview, when asked if I had glass cockpit time; I enthusiastically replied “absolutely”.
