The Hawker Hurricane aircraft earned Elsie the nickname 'Queen of the Hurricanes' as she was the chief aeronautical engineer responsible for the retooling of Canadian Car and Foundry's mass production of this aircraft for the Battle of Britain and other theatres of the Second World War. In fact, an American comic book had a strip featuring her war work where the title featured.
The challenge of mass production of airplanes at the plant was real. Mass production at the time was much easier when the product in question is simple and the pieces are standardized. Airplanes were very complex and various changes in design as needs changed added additional problems.
