There are four forces that act on an airplane:Thrustwhich works against drag

Lift which works against weight (the force of gravity)

When an airplane's lift is higher than its weight, it can climb and take off. If an airplane's lift can not overcome its weight, it will fall from the sky or not take off at all.

In the case of a spacecraft, if it is being launched with the aid of a rocket, the force of the rocket engines will propel the rocket into space. The propulsion force of the launching vehicle will have to be stronger than its weight in order for it to lift off. If the rocket engine(s) fail or are not generating enough force the rocket will fall or not lift off at all.
