Thank you for the question.
Again, I think there's always a need to look at the particular circumstances. In the case of Estonia, it's a very crowded airspace in the Gulf of Finland, which has Estonia and Finland on the other side and Russia transiting through from mainland Russia, if I can say that, to Kaliningrad. There are parts of it that are international airspace and parts of it that are the airspace over Estonia.
The Russians, in the past, have often gone through or have mistakenly gone through—either deliberate or not—and a judgment call needs to be made by the commanders who are controlling the airspace and the pilots, again, in terms of what it is that is going to happen at that time, where those aircraft are, what they're doing and what the danger is to civilian populations, etc.
