Given your granfather's high profile in piloting VIPs I wonder whether whilst on Britannia’s he was involved in similar VIP flights?
I was stationed with the RAF in Ceylon (Sri Lanka) in 1957 and was present when the Duke of Gloucester (the Queen's uncle) passed through RAF Negombo (Katunayake) in August 1957 on his way to Malaya where he represented the Queen at the Malaya Independence celebrations. These took place in Kuala Lumpur on 31 August 1957. His BOAC Britannia G-ANBG made a short refuelling stop at Negombo that warranted a local welcoming party of official "meeters and greeters" supported by a display of flags and bunting as seen in my photo here.
The two black and white photos above were scrounged from the R.A.F. Negombo photographic section whose official photographer photographed the event for posterity. I think the young man with his back to the cameraman is the Duke of Gloucester’s son Prince William of Gloucester (he would have been about 15 or 16 at the time). Prince William died in a plane crash at Halfpenny Green in August 1972.
Anyway passed on for information.
