Another flight recorder of the ill-fortunate Tupolev-154 that crashed near Sochi last Sunday morning has been recovered from the seabed, TASS reports.

“The second flight recorder of the Tupolev-154 plane was spotted and recovered less than 30 minutes ago,” the Defense Ministry’s report runs.

Earlier, the plane’s cockpit voice recorder (CVR) was delivered to the Russian Aerospace Force’s research center in Lubertsy, near Moscow. Primary analysis of the data already retrieved from the first recorder has allowed for narrowing the range of likely causes of the plane’s crash.

Divers have retrieved a total of 15 bodies and 239 body parts from the bottom of the Black Sea, the ministry said.
