The black boxes of the Ukrainian passenger plane downed in Tehran on January 8 are still in Iran, the Transportation Safety Board of Canada (TSB) said in a statement on Thursday.
Canadian specialists are taking part in the investigation of the crash, TASS reports.
"The TSB understands that the aicraft's flight data and cockpit voice recorders — the "black boxes" — are still in Iran, and that Iran is assessing options for their download and analysis, including doing it in Iran," the statement said.
"The TSB has been invited to participate in the download and analysis of the recorders and will deploy a second team of investigators who specialize in aircraft recorder download and analysis wherever and whenever that activity takes places," the statement added.
