Air India — Flight AI300

Air India Flight 300, a chartered Lockheed L-749A Constellation named Kashmir Princess, was destroyed by a time bomb while transporting delegates to the Bandung Conference. The explosion occurred approximately five hours after departure from Hong Kong, causing a fire in the right wing that led to a loss of control and a crash into the South China Sea. The bombing was an assassination attempt targeting Chinese Premier Zhou Enlai, who had changed his travel plans at the last minute. Sixteen of the nineteen people on board were killed, while three crew members survived the ditching.

Report

Investigation Summary

The flight was carrying Chinese and Eastern European journalists and delegates to the Afro-Asian Bandung Conference in Jakarta. While cruising over the South China Sea, a time bomb located in the wheel well of the No. 3 engine exploded. The blast punctured the fuel tanks and started an uncontrollable fire in the starboard wing. Despite the crew's efforts to manage the emergency, smoke filled the cockpit and electrical systems failed, making a controlled landing impossible. The aircraft struck the water with its starboard wing first, breaking into three sections. Investigations by Hong Kong authorities identified Chow Tse-ming, a janitor at the Hong Kong Aircraft Engineering Co., as the primary suspect. He was allegedly recruited by Kuomintang (KMT) agents and offered a large sum of money and refuge in Taiwan to plant the device. Chow successfully fled to Taiwan on a CIA-owned Civil Air Transport aircraft before he could be arrested.

Final Conclusions

Investigators concluded that the crash was caused by a time bomb placed in the starboard wheel well during the aircraft's stopover in Hong Kong. The Hong Kong police issued a warrant for Chow Tse-ming for murder conspiracy, but the suspect had already escaped to Taiwan. British and Chinese archival evidence points to a KMT special operations group, designated the Hong Kong Group, as the orchestrators of the sabotage. While China initially accused the United States of involvement, the U.S. Senate Church Committee later reported that any such CIA plans were officially disapproved, though some intelligence officers may have acted independently.
