Planes Turkish Air Force were in the sights of the Syrian air defense system.

Currently, Turkish fighter can not openly cross the Syrian airspace, as anti-aircraft missiles Russia has delivered intersect approaching aircraft of the Turkish Air Force to the border and crossing its airspace, fighters can be easily destroyed.

Through the use of advanced anti-aircraft missiles supplied by Russia to Syria, Syrian airspace managed to best protect it from the intersection of aircraft of NATO, which is already causing serious criticism at the command of the alliance, as air strikes is no longer possible.
