MOSCOW — Russia's main investigative body says both flight recorders have been recovered from the plane that caught fire while making an emergency landing at Moscow's Sheremetyevo Airport, killing 41 people.

Committee spokeswoman Svetlana Petrenko was also quoted by Russian news agencies on Monday as saying investigators are looking into three main possibilities behind the cause of the disaster: insufficient pilot qualifications, equipment failure and weather.

Video on Russian TV showed the plane's underside bursting into flames and spewing black smoke after making a hard landing Sunday night. Those who escaped leapt out of the plane down inflatable emergency slides and ran across the tarmac.

Storms were passing through the Moscow area as when the Aeroflot SSJ100 regional jet caught fire during the emergency landing, after it turned back for unspecified reasons en route to Murmansk.
