BBC4 CASTLE COMMANDO
Immediately following the Operation Mincemeat programme was Castle Commando about the training of Army Commandos.
It also found some survivors to talk about their experiences and Major Dunning was one such and still very fit and alert.
It used a 1945 immediately post-war film to capture the training detail. They also merged current colour images of the training school with original black and white imagery of the men from exactly the same camera angles.
Some of the demonstrations and illustrations were not for the squeamish.
To quote one commando at Dieppe - it's almost as hot as Achnacarry House.
And there is RAF content- the RAF refused to supply aircraft.
