Black boxes recovered after Moscow Aeroflot crash
Committee spokeswoman Svetlana Petrenko was quoted by Russian news agencies on Monday as saying investigators seeking the cause of the disaster are looking into three main possibilities: insufficient pilot qualifications, equipment failure and weather.
The State Department said it was "aware of reports of the death of one U.S. citizen" and was in contact with Russian authorities.
Russian news agencies reported that the plane had been serviced as recently as last month. ■
