Jimmy,
You've coincidentally asked your reasonable question on Pprune on the serving officers' "Be Bitter and Twisted" evening.
Picking out the genuine comments will be a useful start for a career of spotting bulls**tters from the good guys. There will be plenty of each.
Find out all the RAF's current deployments and what they've got there- Harriers in Afghanistan etc- and stand in Smith's and read the Air Force mag for free. It's the in house propaganda, so it won't hurt your case.
Good luck, if you're successful, you'll have a great time.
