Gravity, how fast a rocket must fly to escape the Earth?

Web18 apr. 2014 · 1. I guess that aircraft as the name implies uses air to gain and maintain altitude. Lift is a force created by an airfoil in the air. As soon as you remove air (definition of space), you also remove lift possibility, and the object becomes a spacecraft. So an aircraft cannot go to space only using its own capabilities. chimpsticks
