Description de l’éditeur
In 1915, a Swede named Ernest Hedenstrom, living in Wetaskiwin, Alberta, invented an "Automatic Self-Steerage Flying Machine," which he believed would become a deadly instrument for the Allies in World War One and, at the same time make him rich. The invention was twelve feet long, weighed only ninety pounds, and could carry bombs or camera equipment totalling one hundred and ten pounds. The unmanned machine was designed to take off, fly at a given altitude, drop bombs or photograph enemy installations, and return to its starting point. The aircraft would execute a wide circle up to a hundred miles in length with the bombs being released or cameras activated automatically at a predetermined point on its flight.
