Design by William Henson (1812-1888) and John Stringfellow (1779-1883), inventors from Somerset, England, for the Aerial Steam Carriage. The webbed tail was 15.24m (50 feet) long, and beneath it was a rudder. The steam engine in the car drove two sets of vanes (objects looking like archery targets) 6.09m (20 feet) in diameter. The weight of the machine was 1,360kg (3,000 lbs). The plane was never built. Engraving fromThe Magazine of Science (London, 1844).
