You might not be able to join the RAF as Specaircrew suggests but you could try contacting JEFTS at Barkston Heath who do flying training for the military under contract to Hunting Aviation.
If you wanted the best formation training around this would be your best option. The telephone number is 01400 261201 - try extension 5007 (Admin) and they will direct you to the right person to talk to. I have no idea what the rates would be but it's worth a try.
