I watched a TV episode of Ice Pilots (Buffalo Airways) shot in Canada. They coped with weather changing every five minutes, antiquated aircraft - the most modern looked to be a fifty year old Electra, minimal nav aids, cargoes of all kinds, with the pilots helping with the turnaround. All done without the help of any Nomex overalls or gold braid !
Standard dress of the day seemed to be a 'beanie' hat, scarf wound around the face, several layers of jackets and gloves. I can almost imagine the hysterical laughter if any new intake had arrived for work complete with gold bars.
