I am trying to find out some background info on test pilot John Derry.
There is painfully little or no information on him on the net!
So far I have found out that he was a Test Pilot for de Havilland and was the first British pilot to break the sound barrier in 1948 flying a DH108 and that he was killed in a tragic aircrash at Farnborough in 1952 flying a DH110.
Any information or net sites on this pilot gratefully recieved.
Regards,Colin
