At October 5 2016 the former head of Ukraine Secret Service repeated a claim previously made by the Ukraine secret service:
“The BUK TELAR had the intention to shot down an Aeroflot aircraft but shot down MH17 by mistake. The motive to shot down the Aeroflot aircraft was to blame Ukraine for it and do an invasion of Eastern Ukraine”
Nalyvaichenko did the claim on Twitter.
I blogged about this motive in January 2016. This scenario is extremely unlikely. If this was a planned operation you would expect the TELAR to have a radio connection with an advanced radar and command post located in Russia. This radar is able to identify commercial aircraft. A mistake would would be impossible.
I have no clue who the international experts are claimed by Nalyvaichenko to agree with the scenario of a mistake.
There are many other reasons this story is nonsense. It seems Nalyvaichenko is annoyed why how ways go in Ukraine.
