      Lmao those idiots who want propulsion engines to take us out of the atmosphere, the con men say it would “just” require enough energy to be stored in the fuel tanks!

      Lmao idiots!

        The difference between a catapult and a jet engine is, that the jet engine allows a slow, controlled and steady release of the energy. Once the catapult has released its object it has to go well or else it will come down.
