I do find it slightly odd that the ad gives no indication whatsoever of what you could find yourself doing in the RAF. I'll admit I'm not part of the target audience but it seems a bit of a waste of time if all it does is get a load of people to trapse down to the local recruiting office and then find out that there's nothing they want to do in the air force. Surely it'd be better to attract less people to the recruiting office, but who at least have an idea of a trade they want to follow or whatever. Sort of a quality over quantity thing.
You've got to wonder about the false advertising angle as well.
