Original Note:
Rockets don't need to launch straight up. Rockets utilize Newton third law of motion: "for every action (force) in nature there is an equal and opposite reaction". By firing particles out the engine(s) at a very high velocity, an opposite force is applied to the rocket. https://www1.grc.nasa.gov/beginners-guide-to-aeronautics/newtons-laws-of-motion/
