9Q-CSA is, or was, an Antonov 26 with a Victor Bout pedigree operated by Services Air in the Congo. On 26 May, it crashed at Isiro-Matari, Democratic Republic of the Congo (DROC), killing the three Russian crew members. A Congolese loadmaster suffered severe injuries.
Isiro is in the war-torn northeast DROC, in the midst of the prime mineral-smuggling region of the Congo. It is very possible 9Q-CSA crashed because it was overloaded with coltan or casserite, valuable minerals essential in the production of electronics that are the most lucrative natural resources of that part of the Congo.
"Services Air" is a Kinshasa-based air cargo and passenger airline founded by Congolese warlord Kpama Baramoto, who had been former President Mobutu's secret police chief. They are a comparatively active in the DROC, having recently acquired four ex-Fed Ex 727s.
9Q-CSA was leased from OBC (Original Butt Company) Aerolift. It is the third (count 'em, 3) Antonov connected with Victor Bout crashed in the Congo by Services Air. The others were An-12s 9Q-CER, crashed at Mbuji-Mayi, DROC in 2006, and the famous 9Q-CIH, formerly 9L-LEC, the actual An-12 used in the movie "Lord of War", in which Nicolas Cage played Victor Butt, which crashed at Entebbe in 2005. That's about as distinguished a connection with Victor as you can get.
