In the late 1950's or early 1960, and a year or so before the B 707 became the first commercial jet airliner in the U.S., old Piedmont Airlines operated twin engined Martin 404's ; the 404's has a self contained airstair which extended out of the underneath of the tail towards the rear, much like the rear facing airstair on the much later B 727.
I used to be at CVG
almost every evening delivering 100/130 oct av gas to Piedmont, and after delivering my last load, I frequently rode out to the far end of the airport with the Piedmont mechanics who had to perform engine run-ups on the last plane of the day which terminated at CVG
. If my memory serves me correctly, I'm pretty sure this was before they had any "jet-ways" at CVG
. In those days, the planes parked quite a distance from the terminal, and all the airlines used either an old fashioned stair-truck, or else a self-propelled boarding-stairs. Come to think of it, everything was quite different back then; no TSA
, no "security" of any kind, people regularly helped their friends onto planes and sometimes "hung out" with them in the cabin before the "stewardesses" made all of the "non-passengers" deplane; as a further example of how loose things were at airports back then..........in addition to hauling av-gas to Piedmot, AA
, TWA, and Delta, I would occasionally take a truck load of regular gas to Hertz or Avis. Every time I unloaded at Avis, they had an old three-wheeled Harley that their guys used for shuttling cars to their downtown Cincinnati location. As no one ever used the old three wheeler on the evening shift, I always hopped on it and drove all over the airport, including out on the tarmac where all the ground service guys I knew were fueling planes up. ( I can't even imagine what they would do to you if you tried that today ! )
