Another here who's walked away from aviation, as much as I love the industry I hate it equally and it was a tough descision to turn my back on it after nearly 20 years involved inc RAF and various civi ground roles..
My business partner is also a ex RN fast jet jockey and was close to spunking his savings converting to a civi licence, but didnt and we now have a field based activity centre with off road driving, hovercraft driving and time trials and links with similar local companies to able to offer a whole array of fun stuff to do!
Il still keep what I've got current but just fly privatly when I want, running your own business is hard work but enjoyable and I doubt I could go and work for someone else again.
