Forty-one people died after a Russian plane made an emergency landing and burst into flames just after takeoff from Moscow’s Sheremetyevo airport.
Videos surfaced online shows passengers using emergency exit slides to escape the burning Aeroflot aircraft.
Survivors suggest the plane was struck by lightning, but Russia’s national carrier said only that it returned to the airport for technical reasons.
Two children are among the dead. The jet had 73 passengers and five crew.
Initial reports suggested the plane had landed on fire, but sources quoted by Russian news agency Interfax said the jet caught fire after a very bumpy landing.
The aircraft landed with full fuel tanks because the crew lost contact with air traffic controllers and decided it was too dangerous to dump fuel over Moscow, Interfax added.
“There are 37 survivors – 33 passengers and four members of the crew,” said Yelena Markovskaya, an official involved in the investigation of the crash.
