On the night of 24 August 2004, explosive devices were detonated on board two domestic passenger flights that had taken off from Domodedovo International Airport in Moscow, Russia, causing the destruction of both aircraft and the loss of all 90 people on board them. Subsequent investigations concluded that two Chechen female suicide bombers were responsible for the bombings, which were also later claimed by the leader of the Chechen insurgency. Flights Volga-AviaExpress Flight 1303 The first to crash was Volga-AviaExpress Flight 1303, a Tu-134 aircraft, registered RA-65080, which had been in service since 1977. The plane was flying from Moscow to Volgograd. It left Domodedovo International Airport at 22:30 on 24 August 2004. Communication with the plane was lost at 22:56 while it was flying over Tula Oblast, south-east of Moscow. The remains of the aircraft were found on the ground several hours later. Thirty-four passengers and 9 crew members were on board the plane. All of them died in the crash. The flight recorders were recovered from the crash site. The flight data recorder showed that the plane was cruising uneventfully at , before indicating some type of high energy event likely originating near the right hand side of the aircraft at seat row 19. Both recorders stopped recording within 2–3 seconds of this event. This was followed by the separation of the fuselage at that location an undetermined amount of time afterward. Siberia Airlines Flight 1047 Just minutes after the first crash, Siberia Airlines Flight 1047, which had left Domodedovo International Airport at 21:35 on 24 August 2004, disappeared from the radar screens and crashed. The Tu-154 aircraft, registered RA-85556, which had been in service since 1982, was flying from Moscow to Sochi. According to an unnamed government source of the Russian news agency Interfax, the plane had broadcast a hijack warning while flying over Rostov Oblast at 22:59. However, it was later determined that this was the aircraft's Emergency Locator Transmitter (ELT), and that the crew of flight 1047 were not aware of any danger prior to the aircraft disappearing from radar. The plane disappeared from radar screens shortly after that and crashed. 38 passengers and 8 crew members were on board the plane, and there were no survivors after the crash. The debris of the aircraft was found on the morning of 25 August 2004, from the work settlement of Gluboky in Kamensky District of Rostov
