Why do we have to fly rockets straight up and out of the atmosphere? Why can’t we fly a ship like a plane and just go higher and higher and higher, then rocket booster out past the exosphere. I know the air is thin way up there, so at the highest, tilt upwards and rocket boost

Why do we have to fly rockets straight up and out of the atmosphere? Why can’t we fly a ship like a plane and just go higher and higher and higher, then rocket booster out past the exosphere. I know the air is thin way up there, so at the highest, tilt upwards and rocket boost

Answer 1

You need wings and control surfaces to fly like a plane, and they become redundant (excess weight) when you leave the atmosphere. Orbital rockets start going straight up, but soon roll over to take an orbital path
