Russia's MFA denied it, but even according to what Estonia itself put out, the violation was Russia barely grazing their air space over open water:
Russia has to get to its Kaliningrad territory somehow, and they won't always perfectly thread the needle in the Gulf of Finland, that's just a geographic reality. It's happened before and it will happen again, with ships or planes. The Baltics need to get over their butthurt.
So this is another big nothing burger just like the Poland drones story. Of course the Euros are using it to fearmonger and saber rattle, but they do that with everything involving Russia. They always love having an excuse to talk among themselves and feel important.
And yes there are some who are desperate to draw NATO into direct confrontation with Russia, but that's not happening. The Europeans are useless and the US have made it clear they have no interest in that, their resources are already overstretched as is.
