Hauptmann Otto Jindra was an Austro-Hungarian flying ace during World War I, credited with nine aerial victories while flying as an aerial observer. He doubled in excellence as a leader and administrator. After World War I and Austria-Hungary both ended, Jindra became a major mover in founding a Czechoslovakian air arm, which he eventually rose to command. Jindra graduated from the Artillery Academy in Vienna in 1905, and went into the 14th Mountain Artillery Regiment.
