Eli5: Why can’t airplanes get into space?

1.82K views

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 are held aloft by the lift generated from air flowing over the wings. If you go high enough there isn’t enough air to create the necessary lift, and so you come down.
