In 1942, three Douglas DC-5 aircraft were bring operated from Batavia (now Jakarta, Indonesia). The three aircraft were used in the 1942 Dutch evacuation of civilians from Java to Australia, during which one was damaged in an air strike by the Imperial Japanese Army Air Service at Batavia Kemajoran Airport, on February 9th, 1942, and was abandoned there.
Japanese forces captured said aircraft, registered PK-ADA, and it was subsequently repaired and tested it at Tachikawa Airfield and Haneda Airport during 1943. This DC-5 was then painted in camouflage with Imperial Japanese Army Air Service markings.
The DC-5 was initially flown to Tachikawa Air Force Base, Japan, from Indonesia, by Huruo Odagiri, where it was test-flown by the Japanese Army Air Technical Intelligence Group.
During the next two years, the aircraft was extensively flight tested, as the Japanese were particularly interested in the wing slots, dihedral tailplane, and the relationship of the design to the Douglas A-20. Apparently, results of these tests were disappointing to the Japanese, who expected it to compare with the DC-3.
She would go on in Japanese hands to serve as an experimental transport and cargo plane, as well as radio-navigation training aircraft.
