Why is it a rocket🚀 is used to go straight up into outer space and not just use an airplane ✈️ ? I’m sure there is a good reason but it seems that the gradual assent would be preferred over the straight up approach.
Planes don’t carry their own supply of an oxidizer to burn fuel against, since the atmosphere provides oxygen for the engines. They are also designed to propel themselves laterally with engines, using lift generated from the wings to lift the aircraft.
