Russian Transport Minister Yevgeny Dietrich said that 41 bodies had been recovered from wreckage of plane that caught fire at Moscow's Sheremetyevo Airport.
The minister said that the investigators had started researching the black boxes.
"The Interstate Aviation Committee is now decrypting the parametric recorder and working with two other black boxes," Sputnik cited him as saying.
The statement comes after flight SU1492 from Moscow to Murmansk crashed in Moscow at 2:50 pm GMT on Sunday. The aircraft had to undertake a rough landing just 28 minutes after takeoff that resulted in the collapse of the wheels and combustion of the engines.
The crew managed to begin the evacuation process, however, many people received burns or suffered gas inhalation. According to the Health Ministry, at least 9 victims remain in hospital in critical or moderately severe condition.
