Blimey, its like asking a bunch of prison inmates if its a good idea to come and join them!
If you are interested in a miltary career and you want to fly, then the RAF, FAA and AAC are all options available to you. If you are not already a member join the ATC or something similar, think about joining - it will give you a taste for military life with all its ups and downs. Make sure you are not colour blind as well.
Despite whatever happens in the defence review we will always have a military and it is a good career if you are tempramentally suited to it. If you are not you won't make it through selection. If you just want to make money, then you will be better off in civvy life. Even the Airships don't get paid much by comparison. There are big upsides to being in uniform - but that's a different subject all together.
