The Tatarstan Airlines' Boeing 737-500 crashed on landing at the airport in the Volga city of Kazan after a flight from Moscow's Domodedovo airport yesterday night, killing all 44 passengers and six crew on board, the emergencies ministry said.
"The main versions of what happened are an error in piloting and technical factors, including a technical failure," the head of the transport Investigative Committee for the Volga region, Alexander Poltinin, was quoted as saying by Russian news agencies.
Transport Minister Maxim Sokolov, citing what he said was so far unpublished video footage of the disaster, revealed that the plane plunged nose first into the grounds of the airport and then appeared to have exploded.
"The plane simply fell. It went vertically into the ground. After the plane hit the ground there was an explosion," Sokolov was quoted as saying by the state RIA Novosti news agency in Kazan.
The disaster claimed the lives of Irek Minnikhanov, the son of the leader of the Tatarstan region, Rustam Minnikhanov, and the head of Russia's FSB security service in Tatarstan, Alexander Antonov.
Also among the dead was a Briton, Donna Carolina Bull, 53, and a Ukrainian national, Margarita Oshurkova, the emergencies ministry said. The rest of the victims are all believed to be Russian citizens.
Despite his personal tragedy, Minnikhanov was at the scene of the disaster and overseeing rescue operations, Russia's Deputy Prime Minister Arkady Dvorkovich told a cabinet meeting.
