An aircraft propeller stands inside a German Aeronautical materials testing laboratory. Materials testing machine is turned on. The propeller is turned on soon after. The machine tests the propeller, turning at high-speed, until the propeller shatters. The propeller breaks into many pieces, with debris flying all over. A technician climbs down from ladder. Another propeller is tested under high speed. A German scientist is seen observing the propeller.
