When I was flying my ickle 152 out in the States I would fly into some right pokey little dogholes on x-country flights. I would occasionally see these FTO students and their instructors with gold bars on their shoulders, ray bans across their dial and that air of pompous coolness that would suggest they fly a Lear or something equally as "arousing".
Then I would step outa my ickle 152, trapse across the apron with tatty shorts and t-shirt and a rather nasty looking mexican moustache. My shoulders would not be held back and my step sure as !!!! weren't springy..... but then it didn't need to be.
The issue here is what role I was in at the time and whether I had to look the part. I didn't need to look the part but the FTO chaps did as they were from an organisation whose purpose is to make money and maintain a reputation.
I would hazard a guess that they were as much against gold bars, shirts and ties as most posting here including myself but thems the rules and like alot of things when training one just has to lap it up and gulp it down.
VFE.
