Constance Babington Smith, head of the Central Interpretation Unit at Medmenham in Buckinghamshire, summed Warby up: ‘The photographic pilot has to have all the accuracy of the bomber pilot, as well as the alertness and tactical skill of the fighter pilot. In addition, he must be an individualist who can make quick responsible decisions entirely on his own. And he must have the persistent purpose and the endurance not only to reach his target but to bring back the photographs to his base. In all these things Warburton excelled … . The names of Bader and Gibson are rightly famous, but the name of Adrian Warburton has hardly been heard outside the circle of those who actually knew him, and there is no single mention of him in the official RAF history of the Second World War.’
