Yep, instructors, and, all the rest of our esteemed colleagues who've been doing a sterling job in light aircraft since gaining a CPL/fATPL. I expect they know less about flying jets than people with jet or turboprop multi-crew experience but they know considerably more than people with <500 hours, have proven themselves, and also put something back into aviation. This group of deserving and well qualified wannabes are becoming the forgotten pilots. New hires by EasyJet would now seem to be either rocketing past on a fast-track up from nowhere -- the wannabes who have neverbeen -- or parachuting in from another airline, often infact from another country.
If it was because anyone who's gained, say, a thousand hours in non-airline flying will invariably be scarred for life by the experience and can only therafter make a crap airline pilot, then fair enough, but I don't believe that is necessarily the case. Is it?
