Our aviation makes much more sorties than Russians. If we have to go around Russian planes in Syrian airspace, then within a short period of time.
At the same time, the US Air Force commander for some reason did not explain how it turns out that American aircraft and drones are in the skies of Syria significantly more Russian in time, and of the recent successes of the US Air Force - only two defeated excavators ...
Meanwhile, the head of the Pentagon, Ashton Carter, spoke in favor of beginning early negotiations (second round) between representatives of the Russian Defense Ministry and the US military. According to Carter, successful negotiations will reduce the risks for US and Russian aircraft during the operation of the US Air Force and the Russian Aerospace Force in the skies of Syria.
Recall that just a few hours ago, in the same Pentagon, they stated that they did not intend to hold any consultations with Russia as long as Russia "supported Assad." At the same time, Washington accused the Russian Space Forces of the Russian Federation that ISIS terrorists are allegedly not targets of air strikes.
Now they started talking about consultations again after seeing Russian airplanes on radars. Washington's opinion changes several times in one day.
