Following on from DOC's comments, it is the European business unit that also suffers, as the previously abundant inflow of returning overseas pilots has all but dried up. Historically the rounding of experience for North Sea pilots came either from a military background, or from serving on overseas ops. Now, increasingly, there is a breed of pilot in the North Sea who has only flown one type from one base. That's not a healthy situation, though not one any HR manager would acknowledge as a problem (or, perhaps, those pilots on one type from one base!).
