JAG3,
I know a bloke who was in Queens OTC about 5 years ago. He applied for RAF Aircrew in his 2nd year at uni and was accepted. The RAF insisted that he leave the OTC and he was transferred to MSUAS so that he could get some flying experience prior to attending IOT.
He is now a Nav on E-3s.
I would definately say join the OTC if you can. Its like the TA, ie there is cheap drink and you get to play soldiers - but the women are better looking and there's no chance of being sent to Iraq..
You'll have plenty of opportunity to work with ugly women and be in Iraq when you are in the RAF.
