Saddened to hear of his passing. Truly one of the best at not just being a test pilot, but also at writing. I'd like to think I saved him a lot of time when he was writing the Flight Testing book - when I saw it he was treating the computer like a typewriter, and was having a very difficult time with editing. I showed him how to just type in the text and format it later. He was so grateful I got a copy of that wonderful book from him.
I doubt he's resting - a soul like his will be wandering the starry firmament and testing out his own wings...
