Mark wrote many articles about aircraft he flew, WW 18 is obviously my fave as he writes about flying the ex Black Knight T-33. After he died I e-mailed S Conner who had recorded lots of interviews with Mark as well as having him talk over in-cockpit cams & release it all on DVD.
I came across the youtube vid of Mark describing his Hunter display, he would have made a superb instructor.
PS…..I’m saving the article to read at the weekend, many thanks for posting it up!
