The RAF don't look at you just for your potential as a flyer. Unfortunately/fortunately/whichever way you look at it, they are primarily concerned about your potential as an officer/SNCO. Rightly or wrongly, they want someone they can mould into the ambitious, capable military man/woman that they want and hopefully, you'll be a good pilot too!
Also, forgive me for being slightly presumptious, but I'm sure all of you who have ambitions toward the military route are well aware that it's not always an easy ride? You will be asked to spend many months of the year away from home, friends and family (especially if you end up on helicopters). You will be expected to carry out mundane duties in addition to your normal everyday workload, oh and just in case you'd forgotten, you might be asked to do some pretty dangerous things in some pretty desperate conditions too? FTLs? There are rules but not when you're in a fight!
Up for it? Then you'll have a great time and some great stories! Like your comfy family life? Stay well away.
