Good luck with your selection mate, hope it goes well. I have a good chum and ex RAF NCA colleague who went over to the dark blue side as Aircrewman on Merlins. Seems to enjoy it, but now that the RAF are getting back into the maritime game after a wee holiday (P8 Poseidon), he's quietly thinking he'd like to jump back.
Big boys new toys? Or systemic problems in the RN.......
You'll never know unless you try it! Crack on shipmate.
