I do not know if the aircraft violated Turkish Airspace. I do know the pilot of the Turkish Aircraft had orders to shoot the Russian Aircraft if it violated Turkish Air Space. There is absolutely no way he could have received authorization to fire in the 15 to 20 seconds the Russian aircraft “may” have been over Turkish airspace.
The real question is why the pilot of the Turkish aircraft had the orders he was given.
I think the orders were given to help out their muzzie jihad buddies hanging out close to Turkey’s border, who were taking a pounding from Ruskie aircraft.
Two thoughts The Turks thought they needs to put a warning shot across Putins bows. There are things in that area the Turks want to protect. Which raises the interesting question, just which side is Turkey actually on?
