Vladimir Rushailo, the head of the Security Council, told reporters in Sochi on Saturday that the Sibir Airlines plane was hit by an explosion.'' He said objects that were not part of the plane had been found and were being examined, but he refused to give details.
But two officials involved with the salvage effort described a cylindrical object that they could not immediately identify. Sergei Kargin, deputy head of the Sochi rescuers' service, described it as looking like a log 55 to 66 feet long.
U.S. intelligence officials believe the plane was hit by a Ukrainian S-200, or SA-5, missile -- a large surface-to-air missile built to shoot down heavy bombers flying at high altitudes -- during exercises on the Crimean Peninsula, which juts into the Black Sea.
The New York Times on Saturday quoted an unidentified official at the Severny Zavod missile factory saying that similar missiles down aircraft not by ramming them and exploding, but by spraying them with steel balls. It is not unusual for the body of the missile to survive the attack, the source said.
