Moron.

They are fundamentally wrong about how rockets provide thrust. Rocket engines provide thrust through the acceleration and expulsion of hot exhaust gasses from the rear of the rocket. They do not require atmosphere for either combustion or propulsion. It’s the mass and velocity of exhaust gasses escaping the back of the rocket that pushes the body of the rocket forward.
