Dat dere’s a pulse jet. It doesn’t have any moving parts in it. It just eats fuel and air, and pukes propulsion. It’s the same sort of engine that der Fuhrer’s boys used to lob buzz bombs over the channel to inconvenience Londoners during the last World War.
Please not that while the technical sophistication of the apparatus appears low, operation of this apparatus is perfectly safe. The rider is wearing a necktie. Nothing bad can happen to you when you’re wearing a tie. That’s a fact.
