The late Dennis Warren, - when I knew him he was head of Design Liaison, Dunsfold - was involved on the speed record runs.
A very clever designer & engineer, he was never even aware of the book ( we were at the same sailing club, and if that sounds snobby or elite it certainly isn't - one day Dennis had got stuck in the mud working on his little boat's mooring, ending up with a SAR winchman in about as much trouble ).
Anyway one of all the most rewarding things I have done in life was giving Dennis that book, ' Faster Than The Sun', you could have seen the grin 10 miles away - gone now, as is our mutual work & sailing chum, Charlie Solley.
Back to the point, another source would be to search ' Test Pilots Tribute Site' - you will get good results, the great guy running it 'tartan terror' helped me resolve a good friend's last wishes.
