'Aeroplane' magazine carried quite a comprehensive article on him during the '90s. It gave a pretty full account of his background and flying career, including the details of the composition of "High Flight" His death was the result of a mid-air collision with (from memory) an Anson on a training flight. I have a copy of the particular issue - if the need is great, I could scan and e-mail but it is somewhere among my stored bits and pieces so may take a while.
