In 1934, North American Aviation developed the O-47 to replace the O-19 and O-38 observation biplanes. Larger and heavier than most preceding observation aircraft, its crew of three sat in tandem under the long canopy. Since the wings restricted downward observation and photography, North American put windows in the aircraft's deep belly.
