Allan Williams, manager of the National Collection of Aerial Photography based in Edinburgh, which now holds Tara, said: "The skill of the photo reconnaissance pilot was incredible - they were among the best pilots in the air force. As so many of them lost their lives the archive has become a memorial to them and the events on the ground they photographed. How they could take the photos they did is astonishing. When you remember they were taken in combat, and often being shot at - it's astounding"
