On August 24, 2004, two Tupolev Tu-134 and two Sibir Tupolev Tu-154 aircrafts crashed in Volgograd, Russia, resulting in the deaths of all 44 passengers and crew. An explosion occurred inside cabin on the right-hand side of seat row 19, followed by an explosive decompression and subsequent breakup of the aircraft. The crash occurred almost simultaneously with a Sibir Tupolev Tu-154 flight departing Domodedovo earlier that same day. Explosive devices were discovered in the wreckage, suggesting they were carried by a female passenger. Two Chechen women, one arriving from Makhachkala and the other purchased tickets on both flights, were involved in the incident. They were subsequently bribed to bypass security and board the Tu-154.On August 24, 2004, two Tupolev Tu-134 and two Sibir Tupolev Tu-154 aircrafts crashed in Volgograd, Russia, resulting in the deaths of all 44 passengers and crew.
