Passengers and crew on board a jet that was forced to make an emergency landing at a Moscow airport say it was struck by lightning moments before it crashed.
Reports of the strike came as survivors told how they escaped the Aeroflot jet which burst into flames on landing at Sheremetyevo airport on Sunday.
Forty-one of the 73 passengers and five crew were killed in the accident.
Investigators probing the cause of the crash have made no official comment on the claims it was hit by lightning.
Modern aircraft are built to withstand lightning strikes, and Russia’s national carrier has said only that the plane returned to the airport for “technical reasons”.
However passengers said the plane was struck just after takeoff, and crew members also said lightning appeared to be responsible for a loss of communication with air traffic control.
Dramatic video pictures showed the plane making a very bumpy landing, bursting into flames after bouncing on the tarmac.
One passenger who survived the crash, Petr Egorov, was quoted as saying that the flight “had just taken off and the aircraft was hit by lightning”, adding: “The landing was rough – I almost passed out from fear.”
Another survivor, Mikhail Savchenko, said he managed to escape by jumping out onto the emergency exit slides at the front of the Aeroflot jet while the rear was ablaze.
Another witnesses said the plane “jumped like a grasshopper” as it struck the runway at speed.
