Douglas O-38

The Douglas O-38 was an observation airplane used by the United States Army Air Corps in the 1930s and early 1940s. Between 1931 and 1934 Douglas built 156 of them for the Air Corps, eight of which were O-38Fs, and some were still in service at the time of the Pearl Harbor attack in 1941. It was a modernized derivative of the O-25, itself a re-engined variant of the earlier Douglas O-2. Export customers included Peru, which received six on Edo floats in February 1933, three of which took part in the conflict against Colombia, and Haiti, which received six in June 1942 and retired them in 1948. The sole surviving example is displayed at the National Museum of the United States Air Force.
