Coincidently stumbled on this...... It's highly likely that he worked on the plane that shot down the Red Baron.
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 some research has suggested that it may be unlikely that Brown fired the bullet that caused the death of Von Richthofen, he is still officially credited with Von Richthofen's loss. What is less well known, but perhaps much more impressive, is that Brown never lost a pilot in his flight in combat. 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.
The record of Britain's Royal Naval Air Service (RNAS) is somewhat murky for the general reader, and its accomplishments definitely play second fiddle to the Royal Flying Corps (RFC). However, RNAS pilots and their aircraft took a back seat to no one and fought against the best the Germans sent over the lines, including the redoubtable Red Baron and his Jastas. No. 10 Squadron helped initiate Sopwith's graceful little triplane to action, and also included several high-scoring aces on its roster, such as Canadian Ray Collishaw, who eventually tallied a grand total of 60 kills and saw service in WW II as an air commodore.
Largely composed of Canadians, No. 10 reformed in May 1917 with three flights (roughly equivalent to modern divisions), which included Collishaw's famous "Black Flight," so named because its triplanes had their forward fuselages painted black and carried names such as "Black Roger" and "Black Prince." This well-researched account gives a daily chronology of squadron activities, along with terrific photographic backup, showing the somewhat slap-dash organization of the RNAS units at the time.
