Investigation Summary
The flight of VT-CLA was a humanitarian mission intended to deliver medical aid donated by the Red Cross of Malaya to the Red Cross of Indonesia. The aircraft was owned by Indian national Bijoyanda Patnaik and operated by Kalinga Airlines on behalf of the Indonesian government. Although the flight was approved by Allied forces and its registration and mission were broadcast via Malayan radio the night before, the Dutch military later claimed they were unaware of the flight and that the aircraft lacked Red Cross markings. The interception occurred at approximately 10:00 a.m. local time as the Dakota was descending with its landing gear down. Two Dutch P-40 Kittyhawks, piloted by First Lieutenant B.J. Ruesink and Sergeant-Major W.E. Erkelens, strafed the transport, focusing fire on the left wing and engine. The aircraft lost control, struck a tree, and crashed into a field, leaving only the tail section intact. While the Bureau of Aircraft Accidents Archives records 7 fatalities, local records and Wikipedia detail 8 deaths: 7 on impact and one survivor, Beryl Constantine, who died later at Bethesda Hospital. The Dutch initially denied involvement, suggesting the plane had simply crashed, but ground witnesses and a post-mortem examination of a victim confirmed gunshot wounds. The incident significantly strained relations between the Netherlands and India, eventually leading the Dutch to provide a replacement aircraft and financial restitution.
Final Conclusions
The crash was caused by a deliberate shootdown by two Royal Netherlands East Indies Army Air Force (ML-KNIL) Curtiss P-40 Kittyhawk fighters. The Dutch government eventually acknowledged the incident and provided restitution to India, though they maintained the pilots mistook the civilian transport for a military aircraft due to the lack of visible Red Cross markings and the heightened state of hostilities following Indonesian air raids earlier that morning.
