Convoy PQ 18, Soviet-Based RAF Bombers and the Battle Against Hitler's Last Great Warship With links to the Great Escape, the story of this unique operation is revealed here by Geoffrey W. Raebel, the son of the surviving senior engineer of 455 Squadron. This the result of thirty years of research and draws in great part on the personal accounts of the men who took part in that historic enterprise. It is supplemented with rarely seen Coastal Command photographs, German ones that have never been published before, and the full story of the discovery, and recovery, of one of the bombers involved.
