4) was a derivative of an early aircraft built by a Canadian-U.S. team, which after many successful flights in Hammondsport, New York, earlier in 1909, was dismantled and shipped to Baddeck, Nova Scotia. It was flown off the ice of Baddeck Bay, a sub-basin of Bras d'Or Lake, on 23 February 1909, making it the first controlled powered flight in Canada. The aircraft was piloted by one of its designers, John McCurdy.
