Prince Albert (later King George VI), the first member of the Royal Family to serve in the Air Force, prepares for a flight to northern France where he was serving during the First World War. 25 years after the formation of the RAF, King George VI wrote a telegram stating: "To me personally it is an anniversary of great significance...on this day in...1918...there began for me an association of which I have never been prouder than I am today."
