Air Chief Marshal Moran was taken ill while taking part in a triathlon during the afternoon of Wednesday 26 May at RAF Brize Norton, and sadly died later in hospital.
Air Chief Marshal Sir Stephen Dalton, Chief of the Air Staff, said:
It is with great sadness and shock that I announce the untimely death of Air Chief Marshal Sir Christopher Moran KCB OBE MVO ADC MA BSc FRAeS RAF on Wednesday 26 May 2010.
Sir Chris had been the Commander-in-Chief of Air Command for the last 14 months.
During a distinguished career he served in a wide number of appointments; a Harrier pilot by background, he commanded Royal Air Force Wittering and was the Air Officer Commanding Number 1 Group.
Sir Chris was also Equerry to The Duke of Edinburgh in the early 1990s. A highly respected and courageous leader, this tragic loss comes as a huge blow to the Royal Air Force and, indeed, Defence at large.
Most importantly, our prayers and thoughts are with his family, to whom I offer my most sincere condolences on behalf of the Royal Air Force, serving and retired.
