It is in Russia 

Former pilot and regular CNN aviation expert Jeff Wise speculates that MH370 flew north along national borders to avoid radar before landing in Kazakhstan as part of a Russian-engineered plot. Wise's theory is dependent on somebody on board the plane tampering with key satellite transmission data to give the impression it flew south. He noted the relevant instruments could be accessed by a panel in the cabin and that there were three Russians on board. Wise acknowledges he can offer no motive to explain why Russia would want to steal a Malaysian jetliner.
