I left in 2011 as I could see the RAF about to lean itself into a huge capability and experience gap (the fun had already gone several years earlier); lo and behold, 7 years on they want people back because they have a capability and experience gap.....
Apart from the huge paycut, taking a chainsaw to my quality of life and commuting from Australia, I cant imagine I'd be much use, as I'd spend all my time laughing and saying 'told you so'....
