SOCHI (Sputnik) – Technical malfunction or pilot error, not terrorism, are among the leads in the investigation into the Russian Defense Ministry's Tu-154 plane crash, Russian Transport Minister Maxim Sokolov said Monday.
"Today, as far as we know, the main versions do not include a terrorist act, so we proceed from the fact that the causes of this disaster could either be technical state or pilot error," Sokolov said at a briefing.
Sokolov stressed that the authorities do not deem it feasible to introduce additional airport security measures following the early Sunday tragedy in the Black Sea that claimed 92 lives.
