This is sad news for the ME world, but nothing compared to John's wife and family,. So sorry to hear this news. I never met John but enjoyed reading his comments on this site.
My thanks go to Ketan who made us aware of the awful news.
I expect John is already meeting up with past legends of the ME world, Tubal Cain, Professor Chaddock, George Thomas etc
Once again condolences to John's wife and family, we are all thinking of you at this sad time.
