Interestingly enough this is now a very hot issue with the Fleet Air Arm.
My recruiting contacts tell me that new enquiries after 1 Apr 05 will have to be under 24, just like the RAF.
I have mentioned this before but apparently this time the RN is prepared to miss its recruiting target rather than take people up to 26.
Therefore if your considering your options, ditch the gap year and the tentative RAF application (numbers slashed anyway) and get down the old Careers Office before its too late.
