Turks are at present in the Qatari pocket and at odds with the Sauds and UAE , world's top terror exporters. So you never know when like in the 4th crusade when Crusading army just happened to swing by Constantinople, an errand jihadi jetliner might just happen to be low on fuel above Ankara this time round.
* but realistically its just another grand project of the rabid sultan of Turkey , as long as Qataris are paying.
