Apparently the Russian jet was in Turkey's air space.  Seems they radioed the Russian jet 10 times warning them to leave Turkey's air space. 

Just read it on our local news site.  Looks like Putin is getting even more arrogant, daring to let his pilots invade another country's air space.  Sounds totally justified and Putin has more reason to lie than Turkey.  Putin is Syria's ally.  Turkey has a right to defend its territory.  So good for them.
