The "pilot fault" in Borovik Plane crash is the official Russian government version, and I have every reason to view the official Russian government version with suspicion.==
What is this your reason? DO you jave some trustworsy information which no one knows? OR you just suspicious as it is?:))))
It's just a suspicion. Considering Borovik's high profile investigative reporting, it's a natural to be suspicious that foul play may be involved. The very fact that foul-play version was not seriously pursued in Borovik or any other high profile murder or unexplained death, gives a plenty of reason for suspicion.
Also, how about of murder of General Rokhlin, first Chechen war veteran turned vocal Yeltsin Opponent ? Official version says it was his wife who shot him, but his wife vehemently denied it and she recently won the case in the European Court of Human rights of irregularities and abuses during investigation. In other words, whenever unsolved high profile murder or death happens in Putin or Yeltsin Russia, it's a normal to become suspicious.
