Two engineers revolutionized the aviation industry by inventing the jet engine - in England, Sir Frank Whittle, and, across the Channel in Germany, Hans von Ohain. These men discovered a radically different way to propel aircraft. Unprecedented speeds were possible. Increases in engine size and power helped to lower the operating cost per plane. Eventually making travel affordable for all.
Lesson Synopsis: Students demonstrate the Bernoulli Principle, review the influences that affected the Wright Brothers, and make and modify paper airplanes.
