I'm edging into my third decade of Aviation. I've seen the ups and downs - as have many who have similar amounts of grey hair as I.
My advice to the younger and/or aspiring pruners - get established in G.A. or the Big Stuff while it lasts!!.
Without being pessimistic, all we need is another SARs, War/Oil spike or airframe supply issue (Airbus) and the industry will plateau again.
Good Luck.
