Maybe not, a recording could have been made at any time and the Russian jet could have been in Syrian airspace after all.
I would suspect a setup. A Russian plane was coming down at the first available moment whether or not they violated Turkish airspace. Just coming close is all the Turks needed for the excuse to try and get NATO involved. Turkey supports the ISIS, makes billions off them and wants Assad gone bye, bye.
So far, the smartest thing to happen was at the NATO meeting the other day was for them to tell Turkey it is their problem and now they get to deal with The Vlad on their own.
What is disgusting to me is we have equipped Turkey with our near front line weapons and it looks like they are going to have to use them against Vlad. Vlad is gonna turn off their heat for the winter too, a little economic hit that will rile the Turks.
Think about it. I suspect a setup (for example). Russia provokes Turkey into shooting at a jet for the purpose of getting NATO involved, knowing that NATO will be split in the process.
