Brian Walker is a toy inventor from Bend, Oregon who is known for attempting to build his own rocket and as the inventor of several toys, namely the air bazooka. His rocket is known as Project R.U.S.H., which stands for Rapid Up Super High. It was intended to be fueled by hydrogen peroxide and equipped with parachutes for use when landing. The goal of the project is to launch Walker 50 miles into the sky. He currently is waiting for approval to launch 20 miles in a rocket-propelled aircraft from the world's largest crossbow. The crossbow project is now years behind its announced schedule (Fall, 2006).
