Archer,
A lot of them are yes, but are based abroad. It's a big deal for people to be based where they want - one that Ryanair uses to it's advantage. Alas, we are haemorrhaging pilots, especially now that the guys on the old Brookfield contracts are being renewed at a "renegotiated" (Ryanair need to look at the dictionary term) block rate of 83, rather than 85 Euros per hour!
