TEHRAN, January 10. /TASS/. The cockpit voice and flight data recorders, recovered from the Ukrainian plane crash site in Iran, will be opened on January 10, the chief of the Incidents Investigation Board of Iran’s Civil Aviation Organization, Hassan Rezaiefar, told the media on Friday.

"The black boxes of the Ukrainian plane will be opened at the laboratory of Mehrabad Airport," the news agency IRNA quotes Rezaiefar as saying. "If Iran fails to extract information, with the aim of preventing damage to information it will request help from Russia, France, Canada or Ukraine to analyze the black boxes."

He revealed that the voice and flight data recorders were damaged.

"The Ukrainian delegation, too, believes that the black boxes are damaged, but the CVR FDR memory chips are possibly still usable," he stated.

On January 8, a Boeing 737 passenger plane belonging to Ukraine International Airlines went down minutes after taking off from Tehran's Imam Khomeini International Airport bound for Kiev. Ukrainian Foreign Minister Vadim Pristaiko said the crash killed all 176 people on board, noting that among them were citizens of Afghanistan, Germany, Iran, Canada and Ukraine and also British and Swedish nationals.
