Old Duffer,
He never had much to do with the RAFA but I will definitely approach them for a flag for the coffin.
I think Dad is one of the few remaining members of 158 sqn but I will be informing the squadron association once I've got a better idea of his life expectancy which the medics are being surprisingly reticent in quantifying. I suppose it is difficult given his age but there was a general nod of agreement when I suggested that he may see his 70th wedding anniversary in July but that he is highly unlikely to see his 95th birthday in October.
In terms of lucidity he's pretty much all there. He watches the news and comments on the events etc but can comfortably watch reruns as his short term memory span is about 3 minutes.
He's written down a lot of his experiences throughout the war so that's well covered.
