People attend a memorial service to mourn the victims in the AN-148 passenger jet crash near the Cathedral of Christ the Saviour in Moscow, Russia, on Feb. 12, 2018. Rescuers have presumably recovered the second flight data recorder of the AN-148 passenger jet that crashed in the Moscow region on Sunday, the Russian Emergencies Ministry said Monday. On Sunday, an Antonov-148 of Saratov Airlines bound for the city Orsk in Russia's Orenberg Region bordering Kazakhstan crashed shortly after takeoff from Moscow's Domodedovo Airport, killing all people on board, including 65 passengers and six crew members.
