Captain Arthur Roy Brown, DSC and bar RNAS (23 December 1893 – 9 March 1944) was a Canadian World War I flying ace. The Royal Air Force officially credited Brown with shooting down Manfred von Richthofen, the "Red Baron", although it is in fact unlikely that Brown fired the bullet that caused his death. What is less well known is that Brown never lost a pilot in his flight during combat, a rare distinction for an air unit commander of that war. This was due largely to his demands for a "breaking in" period in which new pilots flew over the fights just to see how they worked.
