True Gent.
I had the honour of meeting Jimmy Dell a couple of years ago. A wonderful man who was quite happy to spend a considerable amount of time chatting to a 'nobody' who wanted to hear all of his Canberra/Lightning/TSR2 stories. Also met him some months later, and again he spared me the time for a chat.
Didn't ever work with him, but concur that he is a legend within the world of aviation, and will be greatly missed.
