It happens however to be my personal prejudice that anything with a totally non-aviation content on Pprune, belongs on Jetblast (which includes, I'd suggest, careers in nursing). That I probably didn't make at-all clear.
No, you did make it clear,
Genghis, but my response was not
about those professions, they were simply quoted as examples for comparison. I could just have easily have used cabin crew or ticketing staff instead but didn't think of it at the time.
To be fair though, you too have used examples from outside the aviation industry by quoting the Royal Navy and submarine crewing situation to illustrate your own point.
Something that might make you smile ... I do know a female engineer who actually has a Doctorate in that subject. (She is in Civil Engineering though, not aviation.)
