I was an f/o and capt in Ryanair. Generally had a good run and a good time, but a failure rate of 75% does surprise me, if its true. The reason it surprises me is that for every good f/o I flew with, I flew with twice as many average or truely awful ones, and these were quite common unfortunately.
Maybe the company should reject some of the guys they currently have flying for them, Ps; that goes for some of the Capts too when I was an f/o there!
Some of the great guys and very good pilots that were there, that I knew have left. The good ones that stay for other reasons, well.. the company simply doesn't deserve them.
I'm not an FR basher, like I said I had a good time, but I'm glad I've left all that whining and back stabbing behind.
