Thank you to you all, their is a mass of advice and information so far, a lot of it RAF based. The only reason I have a quandry is that during my IRT time I really enjoyed working with the RN, as I was really made to feel part of the crew and it was much more enjoyable experience. I am sad to say this was not always the case when operating with my own brethren. However on the upside you become a SGT much sooner in the RAF.
