Rocket Power

While researching a story for SB#5, came across this mad bike in Popular Science magazine 1947...BP
A crowd of 90,000 saw Bill Kitchen, noted British motorcycle racer, smoke up Wembley speedway in London recently on the world’s first rocket-assisted motorcycle. Prof. A. M. Low, rocket pioneer, and Alex Jackson, manager of the Wembley track, developed the rocket-boosted bike. The additional power is supplied by four rockets fixed over the rear wheel, two to the side. Kitchen was protected from the blast by a steel shield. Switches on the handle- bars controlled the rockets. The race rider said the “acceleration was absolutely terrific” when the rockets let go.
