My guess is that the outcome or ruling will be...The Plaintiff has not been able to prove without reasonable doubt that the Pilot Did It..
Given Capt Tsu's history, I question why he was flying MI 185 or any other aircraft for that matter, but all evidence available does not actually prove 100% he did it.. That is the problem. Unless there is other evidence not yet made public..
Anyway, it brings the accident to the attention of the public eye again and reminds them that this case is not yet over. One day, the truth will prevail and aviation safety enhanced... I hope..
