Civila Aviation Administration of Israel may reciprocate, but let us be honest: how much damage would Turkey suffer if their flights through Israeli airspace were banned altogether? Not much. They can use Lebanese, Jordanian airspace, or just go over Medditerranian Sea. Fact is, Israel is not a large country, and her airspace of twenty thousand square kilometers is not a barrier at all. On the other hand, Turkey is a vast country, and Israeli flights to Europe traverse it regularly. Remember how many people right here on Haaretz warned that Israel needed Turkey more than the other way around? This is the proof. It is easy for Israeli politicians to talk rough, but when the going gets tough, they are all silent on the matter.
