On June 20, 1964, Civil Air Transport (CAT) Flight 106, C-46D B-908, took off from Taichung’s Suinan (水湳) Airport at 1735 hours but went down five minutes later near Shen Gang (神岡) in central Taiwan. All 52 passengers (including 19 Americans) and the crew of 5 aboard were killed. This is not only the first ever major accident involving a civilian airline in Taiwan, but also very likely the result from a hijack attempt.
ICAO Aircraft Accident Digest described the probable cause as
“About 5 miles west of the accident site was Kung-Kuan Military Air Base. Six miles south-southwest was Shui-Nan Airport from where the aircraft took off. On the right side of the flight pattern was a chain of mountains. It was concluded that, when the pilot found that the left engine was overspeeding, he made an abrupt left turn to land at Kung-Kuan Military Air Base or return to Shui-Nan Airport. During the turn he lost control of the aircraft, which crashed to the ground.”
However, an attempted hijack was suspected because two .45 pistols were found in the wreckage as well as two radar manuals whose inside pages had been carved out in the shape of a pistol. Taiwan’s Digital Archives preserve the newsreel footage clips of the recovery effort, subsequent funerals, and the press conference held by Taiwan Provincial Police Department. The guns and radar manuals can be seen at about 18 seconds into the second video.

Because CAT was partially owned by CIA, the Agency also took part in the investigation. In 2009, CIA released several documents related to the investigation. This cable from the American Embassy in Taipei to State Department included some names of the Americans killed in the crash. Also available is a compilation of various reports. But I think the report titled A Report on B-908 Aircraft Crash Accident Viewed from the Angle of Aviation Medicine, authored by CAT’s company doctor W.S. Cheng, M.D., is most interesting.
Unfortunately, the question of the two guns were not covered in the documents released by CIA.
But it was pointed out that this question is worthy of further investigation:
Although the documents did not name the suspected hijackers, Doctor Cheng’s report devoted quite a few paragraphs to two men, Tseng Yang (曾暘) and Wang Cheng Yi (王正義), especially Wang.
That of course did not automatically qualify them as the prime suspects. Other Taiwanese sources indicated that the two manuals had been checked out from the library of No. 2 Shipyard in Penghu (澎湖) by Tseng, a Navy Lieutenant. As for Wang, a retired Navy officer, his wounds and loss of clothing led to the conclusion that he was standing near the pilots at the time of crash:
Dr. Cheng stopped short of saying that the wounds on the pilot Bengee Lin was inflicted by a gunshot:
Could the spike found in the ashes of the co-pilot M. H. Kung a melt .45 bullet?
