As we’ve reported to you earlier, a Russian Su-24M Fencer was shot down this morning after it allegedly violated Turkey’s sovereign airspace. “Facts” and “truth” are radically divergent at this point, so we’re sifting through what we actually know versus what is being reported.

The incident occurred very near to the Turkish border with Syria, close to where Turkey’s Hatay Province and Syria’s Latakia Province meet in wooded, mountainous terrain. Two Su-24s approached the southernmost tip of Turkey, and were warned via radio to change course 10 times over a period of approximately five minutes. The two Russian fighters, flying at an altitude of 19,000 feet, are alleged to have violated Turkish airspace for a total of 17 seconds at a depth of 1.15 miles and 1.36 miles, respectively, at approximately 0924 local time. The first aircraft diverted to the south, but the second aircraft stayed in Turkey’s airspace and was ultimately fired on by at least one of two Turkish F-16s flying combat air patrol (CAP) in the area.

The Su-24 was reportedly struck by at least one missile and burst into flames, entering a steep dive and crashing in the Turkmen Mountains on the Syrian side of the border, approximately a mile to two miles from that nation’s border with Turkey. Both crew members were able to eject from the stricken aircraft before it crashed.

Here’s where the water gets really muddy, so we’ll break this down for you the best we can:

1) Did the Russian Su-24M fighters actually violate Turkey’s sovereign airspace?

According to radar data presented and radio transmissions, the two warplanes appear to have indeed crossed into Turkey above the town of Yayladagi. Prior to the incursion, they were warned several times to change course. The Russians say they have their own “proof” the aircraft never left Syrian airspace. “The Ministry of Defense would like to stress that the plane was over Syrian territory throughout the flight,” was the reponse from the Kremlin.

2) What were Russian fighters doing in that part of Syria, since there aren’t known ISIS elements up there?

The region in question has been hotly contested in recent days. Syrian government forces, under the cover of Russian airstrikes, have been fighting elements of the Free Syrian Army in that area. Very recently, there was a heated exchange between Turkey’s Foreign Ministry and the Russian ambassador, the former demanding that Russia stop “bombing civilians” in the Turkmen villages which, incidentally, are in the same area where the Su-24 went down.
