If the planes had entered sovereign airspace, sure. They synopsis says the Russians were flying in international airspace, which usually means it's not under the sovereign control of any nation and the Latvians would have had no basis to fire on the Russians.
Personally, I'd love to see the Russians try to stunt their way into someone's airspace and get dick slapped for it, but I doubt that would happen.
Best I can do is cyber-psychosis and some shit from 10 years ago
