It's a no from me as well. The 28 years were fun to start with but as they say 'its not the RAF i joined' and, in my opinion, it will never recover from the downward spirral the MOD started with redundencies a few years back and are now regreting their actions by dangling a rather tastless carrot.
I only did 5 years and having recently experienced the "full time RAF" it isn't even that same as it was in 2011. Would I go back now......nope.
