His Finest Hour (The Story of Dr. John W. Keller)
In Elementary Flying School in Canada, Keller learned to fly old biplanes called Fleet Finches. His instructor tied long red ribbons to the struts of his plane when he made his first solo flight. “I guess it was a warning for other planes to steer clear!” he notes wryly. He polished his training on Prince Edward Island, where he graduated to the powerful 450-horsepower planes called, ironically, Harvards.
