A question for those who are nervous about those flights: do you know how intensive are NATO flights near Russian borders in north-west?
A: About 800 flights of reconnaissance aircraft and some 400+ flights of combat ones in 2019. 30% increase vs 2018 of the former and nearly double of the latter.
All aircraft flying under NATO authority do so with their transponders turned on, always. They are not a danger to commercial air traffic.
