gravity holds you down
wings + forward motion = lift
thrust = forward motion
air resistance = resistance to forward motion
thin air at altitude is easier and cheaper to get through

if you observe the world around, the whole things are according to certain laws in physics.
Physics
Axes have a leverage system based on physics principles. The length of the handle affects the force applied to the blade, and the weight distribution affects the balance and efficiency of the swing. Understanding these physics concepts can help maximize the effectiveness of using an axe.

From a physics standpoint and based on the size of an average horse, the answer is no.
To understand the laws of nature and how nature affects human action.
