An aircraft was reported missing on this date while on a flight from Hong Kong to Vientiane. MacAlan Thompson reported that a Stratoliner was forced to carry out a controlled crash-landing in a river. Captain Jimmy Lieu and the copilot were held prisoner by the communist Pathet Lao for several months then released about May 1975.
Other sources claim Curtiss C-46 XW-PMF (or HS-SKD), c/n reported 22561, was reported missing in the same period on the same flight. Since Stratoliner XW-TFP was seen in the Mekong river, near the Laos-Thailand border in 1986, this is probably the aircraft that "disappeared".
