Citation:
"One night in March, 1943, this airman was the wireless operator of an aircraft detailed to attack Essen. Whilst over the target area the aircraft was hit by heavy anti-aircraft fire. The navigator was killed instantaneously. Flight Sergeant Keen, who was in the astro-dome, had his right foot blown off and received cuts on both legs. Disregarding his wounds, Flight Sergeant Keen regained his seat in the wireless cabin. For over two hours he laboured to repair the damaged apparatus. He could not speak to other members of the crew owing to damage to the inter-communication apparatus. Another airman spoke to him, however, on at least a dozen occasions and found him still conscious and working at his self imposed task of directing the manipulation of various installations. He also offered assistance in navigating the aircraft and actually managed to drag himself on two occasions to the navigator's compartment to obtain essential information. His courage and fortitude in such circumstances were of the highest order."
