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

Rockets don’t fly straight up, they launch vertically and soon after launch lean over to gain maximum horizontal velocity.
