When a vehicle, say a landing aircraft, hits the brakes in an emergency, it’s usually in danger of becoming unstable, inverting and creating an even more dangerous collision.
Today’s invention is therefore an auxilliary, when-all-else-fails braking system.

When the brakes are applied very sharply, ultra sticky foam, of the type used experimentally as a non-lethal weapon, is automatically sprayed from a small tank beside each wheel.
This expands in milliseconds and causes the wheel to slow further in a controlled way, due to its extreme viscosity and adhesion. This foam grips the ground as well as the rotating components pretty nearly equally on both sides of the vehicle and it will also serve to snuff out any sparks which conventional brakes may be generating.
