@inside_decoded Why Rally Drivers Steer a Car in Mid Air The tires touch nothing—but the brakes can still change a rally car's angle in the air. Its spinning wheels carry angular momentum. Slowing them can tip the nose down; speeding them up can lift it. Drivers set most of the car's attitude before takeoff, with the pedals providing a limited adjustment during the jump. Here, “steer” means changing the nose-up or nose-down angle. Turning the steering wheel doesn't make the car turn in midair. The same exchange of angular momentum helps reaction wheels point spacecraft.
