The last Stearman design completed by Boeing, the YL-15 Scout first flew in July 1947 to fulfill an Army requirement for a light observation/liaison plane. Although its high-set tail boom gave its crew unlimited downward visibility, only 12 were built before it was rejected in favor of the less expensive Cessna L-19 Bird Dog.
