It is clearly possible to cross the divide, but it is not easy.. there are many ex ground bods who have done it...several reaching the exalted level of `Airship`(see above)
A word of warning, however, with the demise of Tornado "within a few years" (actual date dependent on the latest oops! oh dear another clusterf*k life extension) there will not be a two seat fast jet in service. This will surely hamper converting Weapons Techs as they must go round in pairs - one who can read and one who can do the joindey-up writing.
Nonetheless - good luck with your endeavors and joining the RAF Gliding & Soaring Association (or a RAF power flying club if you must)and learning how to fly WILL help I`m sure. For trainees, there are active gliding clubs at Cosford, Halton and Cranwell
