Wolfgang Späte (8 September 1911 – 30 April 1997) was a German Luftwaffe fighter ace during World War II, with 99 victories claimed. He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves. For fighter pilots it was a quantifiable measure of skill and combat success. He is attributed by some, for an early, 1938 version of the speed to fly theory, usually attributed to Paul MacCready. Already a talented glider pilot before the war, he went on to become one of the Luftwaffe's foremost test pilots.
