1 Dollar - Elizabeth II No. 310 Squadron RAF

No. 310 Squadron was the first Czechoslovak unit formed within the RAF, stood up at Duxford in July 1940 just in time for the Battle of Britain. Flying Hurricanes, its pilots — most of them veterans of the fall of France — achieved an exceptional kill ratio during the critical weeks of September 1940, a fact that surprised several senior RAF commanders who had initially doubted the combat readiness of foreign-national squadrons.
