The de Havilland D.H. 61 Giant Moth's performance was impressive - it climbed at 900 feet per minute with a normal payload of 1,270 lbs.; had a ceiling of 18,000 feet; cruised at 128 m.p.h. and had fairly good performance with a load of 2010 lbs. In its cabin the Giant Moth could carry eight passengers, their baggage plus fire fighting equipment. With this load it could stay aloft for five hours and cover 550 miles at normal cruising speed.
In 1931 the Giant Moth received international attention when Ontario Provincial Air Service Pilot George H. R. Phillips was awarded the McKee Trophy as Canada's outstanding flyer for his work in flying rescue equipment to the Moose River Mine disaster
