Tim could be abrasive, contrarian and controversial, and didn't suffer fools, as they say.
To those who knew him, however, he was generous, good humoured, and funny, and he was utterly devoted to fostering a wider and deeper understanding of the RAF and of military aviation affairs.
He did an extraordinary job at producing good books and bookazines for publishers who paid very little. I still don't know how he did it.
I wish that I'd been better at keeping in touch.
I bought one of his books just before the Dubai air show, and promised that I'd ring him and congratulate him on my return.
Before I could do so, I learned of his death.
RIP, Tim.
