My GA experience has been limited to Cessnas and none of the really neat ones.
I envy you for having flown on a Comet.
Dan Air had a large fleet of them which they basically used up and then scrapped when the airframe or engines reached some expensive maintenance limit.
I also envy Mola for having had a commercial flight on a Connie. A truly gorgeous aircraft. You can see echos of the four engine Douglas transports in current transports. You see no echos in any of any Lockheed Constellation model.
I got to fly on a Ford Tri-Motor from one of the Lake Erie Islands to the mainland about forty years ago on Island airlines.
I flew on lots of 707s, 727s and 737-200s back in the day where they were in service everywhere, as well as the inevitable DC-9s.
Never got a 720 or DC-8, which tells you that I never flew much on United.
The only other unusual commercial flights I've had involved a CV 440, a Do 328 and even a Do 328 Jet.
The 328 was a neat and fast little turboprop and the jet had fan engines rather than the turboprops. An expensive to operate airplane that saw only limited sales.
Has anyone here flown on either a CV 880/990, a Caravelle or a VC-10?
