Test rocket. Family:

Max Valier, first with the backing of automobile magnate von Opel, then in competition with him, was instrumental in popularising rocketry in Germany in the 1920's. He dreamed of rocket-propelled transatlantic aircraft, but was killed in a rocket engine test in 1932.

1930 April 19 - Valier rocket car Valier has arranged for Dr Weyland to develop a new, powerful liquid rocket engine burning liquid oxygen and gasoline. The car made its first slow run this day, but combustion of the motor was poor and acceleration of the vehicle low.

1930 May 17 - Valier killed in rocket engine explosion While working in Dr Weyland's laboratory on Saturday, the combustion chamber explodes, and a metal splinters pierces Valier's aorta, killing him immediately.

1931 May 3 - Heyland motor Heyland completes development testing of the rocket motor intended for Valier's rocket car. It weighs 18 kg and is capable of producing 160 kgf for several minutes. Although powerful, the specific impulse is thought to be fairly low.
