Investigators hope the black boxes will provide some clues into the cause of a fire and explosion aboard a Russian passenger plane.
Three people were killed and 43 others were hurt as a result of the explosion on Saturday.
Video captured on a mobile phone shows the center of the plane on fire.
The plane was taxiing down a runway in Siberia when flames broke out in an engine, filling the cabin with smoke.
Most of those on board escaped before the explosion.
The Tu-154, similar to the Boeing 727, has three engines mounted on the rear of the plane. The mid-range plane is noted for its ability to operate on gravel and unpaved airfields. However, noise regulations eventually stopped Tu-154s from flying to most of Europe. Russian flag carrier Aeroflot took the plane out of service in December 2009.
