I was a young student who went on the Cranfield schools aviation camp which he was a tutor on.
I used to phone him (on a payphone!) to discuss aircraft designs and corresponded about a new basic trainer. Aged 16 it was very basic.
Fast forward 16 years or so and I have learnt to fly, gone through commercial, CFI certs and teach for Embry Riddle.
Boscombe Down express interest in me and while I didn't get offered to interview, he responded to my queries on email as I was putting slides together.
One day I might get the chance to present them. His book a view from the hover is a great read too. RIP John. Will look out for an obituary.
