SOP for Russia and USA. I believe there is a treaty where either one of them can fly close to each other’s homeland but still be in international airspace and this happens all the time. I researched it because I was tired of MSM reporting this and trying to drum up fear just by reading title of this topic. After trolling the population for 5-6 paragraphs, they will explain this is routine and happens all the time. MSM-13 sucks!
