50 people killed in the resent airplane crash: http://www.reuters.com/article/2013/11/18/us-russia-crash-idUSBRE9AG0A820131118 "Russia and the former Soviet republics combined have one of the world's worst air-traffic safety records, with a total accident rate almost three times the world average in 2011, according to the International Air Transport Association." There are potentially several reasons for that, but one of the major - lack of care for the technical and human factor as well as over-utilizing the fleet without proper maintenance.
