In World War I, there was a pilot called the Red Baron. His real name was Manfred von Richthofen. He was German. He was called the Red Baron because he flew a bright red airplane. He was also a baron. A baron is someone who owns a lot of land. The Red Baron won 80 airplane fights. That is more than any other pilot. One month, he won 22 airplane fights! He received many medals. When he won a fight, he ordered a silver cup. He could only get 60 cups. The silver could not be used for cups anymore. It had to be used for more important things. Later, he taught other people how to fly airplanes. He also taught them how to win airplane fights. One day the Red Baron was in an airplane fight he did not win. He died in that fight on April 21, 1918.
