Air Force Blue

On 1 April 2018, the Royal Air Force will be a hundred years old - a short life by military standards but an extraordinarily important and eventful one. From the start it was special, standing sometimes awkwardly but always proudly a little apart from the existing services. It was a product of the modern age, whose fortunes depended on ever-more sophisticated machines and the right calibre of men to fly them and to keep them airborne.

Its achievements between 1939 and 1945 - when it was Britain's last line of defence and the spearhead of its counter-attack, were central to the entire war effort. During these years, one in four of those in uniform wore air force blue and the ethos of the RAF was indistinguishable from the spirit of the nation. "Air Force Blue" tells personal stories of those who served, using the letters, diaries and memoirs of the participants to create a true picture of what it was like to be a pilot, a navigator, a gunner, a fitter or a WAAF ops room clerk.
