Or regenerate the SFDO ones. Or use the ones currently stored if they haven't been flogged by then.
As for pilots, maybe I'm just thick but if ex Sea Harrier pilots who flew airliners could go back and fly the Sea Jet as RNR pilots, then surely GR7 to Shar would be less of a challenge? I've got a booklet here from a couple of years ago about the RNR Air Branch, there were pilots attached to 899 NAS.
Also a few years ago, I read in Navy News that the RN had about 50 or so jet jocks, including (I assume) those in instructional posts, desk jobs, doing PWO jobs or driving minehunters/patrol vessels/frigates. Has this number declined recently?
