I had the pleasure of spotting both Doves and Herons in commercial operation as late as the mid 'seventies.
The Dove was operated by two small airlines from BKL until one was lost in the lake while the Dove and Heron were both operated by a contractor to what was then Allegheny, later to become US Air, from CLE to a variety of smaller Ohio destinations.
Allegheny also operated the BAC 1-11, many of which could be spotted on their typical banked hub push at CLE, along with a flock of Convair 580s.
The Convairs seemed so quiet as compared to the United DC-8s and American 707s that screamed overhead on approach.
There were also Northwest DC-10s, TWA L-1011s as well as a 747 now and then along with many DC-9s and 727s as well as a growing number of 737s.
Never did spot a Caravelle, although United did have them in the fleet for a bit.
CLE is nothing like as busy these days.
Fun times.
