Sorting out the wheat from the chaff there but i suspect you would never in a month of Sundays get a job as a journalist on the Daily Mail.Business as usual, then? Neither side recognises each other's claims to territorial waters and air space. If Turkey (who claims very few islands in the Aegean) recognised Greece's claims, vessels could only reach Izmir and the Turkish Straits (Dardanelles and Bosporus) by transiting through Great territorial waters.
These exercises are held very regularly by both sides to exercise their 'rights' and try to drag in other countries into their spat to seek international recognition of their position. A couple of years ago French, US and UK aircraft were persuaded by the Greek air force to bomb some targets less than 2 miles form the Turkish coastline, and turned through Turkish airspace to line up for the run in. Turkey, naturally, was a bit p!ssed off.
"a pair of Turkish fighter jets on Thursday entered Athens’ Flight Information Region (FIR) without submitting a flight plan and flew over two islets of the eastern Aegean, the Greek National Defense General Staff (GEETHA) said."
The FIR is not territorial air space and military aircraft are not required to submit FPs in these circumstances. There are others on this site better versed on the insanely complex arrangements within the Aegean (such as not using your embarked helo to transfer a casualty to a hospital on an Aegean island).
In sum, nothing to see, move along...
