On June 17, 1919, the pioneering aviator Franz Zeno Diemer sets the airplane altitude record with a 32,000 ft (9760 m) flight. It was a significant technical and competitive accomplishment for the day. This historic flight was achieved only through the brilliant breakthrough of the BMW IIIa engine, from which the BMW IV was based. Diemer stated at the time, "I could have gone much higher, but I didn't have enough oxygen."[5]
