Before the eyes of 3000 invited guests, the Opel RAK 2, Fritz von Opel's rocket car, set a speed record in 1928 at Berlin's AVUS race track. The Opel RAK 2 managed a top speed of 238 km/h with the help of 24 solid-fuel rockets packed with 120 kilograms of fuel. Fritz von Opel chose the high-speed AVUS track in Berlin because the company's racetrack was not engineered for speeds over 140 km/h. Men fix rocket boosters on the car. The car moves at a high speed. It releases large amount of smoke as it moves. Crowd watches the car. Photographers take pictures.
