Here's my tuppence worth. Started in aviation in 1971. Now doing what I want to do where I want to do it. I have no jealousy of other people and their professional successes, in fact I take great pleasure in anyone else's success (especially the youngsters) and I seek no promotion or glory.
I've learnt lessons over the years; most important is that anyone that does a job that you do not do has a better knowledge and skill at that job than you. Be it ATSA, ATCO, pilot or bricklayer.
I could never have achieved any success in my profession without the knowledge, support, friendship and encouragement of all, of whatever grade or job description. They all contributed and supported my growth within my profession.
Them and us, us and them? Same team actually and those that don't recognise it are either vain or extremely foolhardy. Or perhaps both?
Oh dear!
