Mark always used to take the p!$$ out of me, in a nice way, and I him, and he always called me his favourite mod, and I used to say that out of all the micro-light flying air gunners I knew, he was my favourite, too .
I am deeply shocked to learn this. Mark will be sadly missed, and other than reiterate things that have already been said, I can't think of owt else to say except rest in peace my friend. My thoughts are with your family.
