Not trying to be a DB... Sorry if it came off that way. I failed my private many years ago.
It's just that after the Colgan accident where the captain had a history of training failures I'm surprised airlines still hire folks with more than one or at most two busts. It's a potential legal liability I would assume. But I'm not in the hiring dept or the training dept so nobody asked me..... Sorry if it came across as dumb.
As to the recent weak guy I flew with? It was an anomaly. 99% of the new folks I fly with are super solid. This one was an exception.
