The remains of the four Hong Kong victims of Wednesday's Phnom Penh air crash have been returned home. But compensation was not expected until the investigation is complete, relatives were told. Cambodian aviation officials have recovered the last 'black box' from the Vietnam Airlines Tupolev-134B jet which crashed after missing its approach to Phnom Penh airport. All but two of the 66 passengers on board flight VN815 from Ho Chi Minh City were killed, including Hong Kong residents Fung Lo-sze, 32, Li Yuk-chun, 52, Ngai Yiu-cho, and Ho Kien-ming, 49. Ho was cremated in Vietnam. An airline spokesman said yesterday some relatives were still in Vietnam to complete paper work, and had asked the airline not to release details. The airline had promised a maximum of US$150,000 (HK$1.16 million) in compensation but the money would only be paid after the investigation had finished. Cambodian officials said investigations had been hindered by looting by onlookers, who stole two of the jet's 'black boxes'. The standby flight data recorder was recovered soon after the crash but onlookers had taken away the other two and had not returned them until days later. Chea Aun, head of the Cambodian Aviation Authority's Air Worthiness Department, said the devices would be sent to the Russian manufacturer for analysis.
