Alfred Fleischer was a German World War I flying ace credited with six confirmed aerial victories.
He served as a grenadier until late 1916 before transferring to aviation and becoming a fighter pilot.
In an unusual turn of events, he became friends with an American pilot he shot down.
Fleischer would return to Germany's service during World War II, commanding air bases in Russia, Hungary, and Yugoslavia.
Postwar, he would move to the United States with the aid of the pilot he had downed in World War I.
