Duke of Edinburgh Learning to Fly - White Waltham 1952
The picture above shows The Duke of Edinburgh inspecting the cockpit of his Chipmunk aircraft at White Waltham, in which he learnt to fly, with his instructor Flight Lieutenant Caryl Ramsey Gordon.
Although I know WK518 reasonably well ... I can't confirm that the above pic is the old girl or if TDoE learnt to fly on her
