Or how about recognising that the standards required for streaming someone FJ vary enormously according to the availability of slots. Why not look for those keen young chaps who found themselves streamed rotary or multi who could (perhaps with a longer, differently structured TWU and OCU) be developed into fast jet aircrew. There could even be an emphasis on getting people through the course, rather than chopping them at FHT, or whatever. They might never become even pairs leaders, but they'd fill cockpits, and get a crack at doing what many of them joined to do. And I'd venture to suggest that recruiting a generation of multi-engined co-pilots would not need to be that difficult, though they wouldn't be the same as today's arguably over-qualified and 'over-calibre' right-hand seaters.
