This is a coloured photograph of the balanced forces acting on Felix Baumgartner’s body during freefall. He is shown in position horizontal to the Earth’s surface. He has reached terminal velocity. A downwards arrow to the Earth is labelled as the gravitational force equalling the force of air resistance; an upwards arrow away from the Earth shows that Baumgartner’s speed is constant, he neither accelerates nor does he slow down.
