Very sad news! Did 4 medicals with him while I was a CAA ATCO at Boscombe, then all bar one of my annual meds after posting to LHR in '86 until retirement.
Smashing guy with loads of interesting tales to tell, particularly of his time in Saudi when IIRC he was the Aeromed Man for their Lightning guys.
I guess he must have been in his early 70s?
Condolences to his friends and family.
