Take a look at the incredible moment a Russian fighter jet flies so close to an American Reaper in the skies above Syria that the pilot can see drone's propeller rotate in the sky(photo)

Russia's Defense Ministry released a clip (left) from inside a Russian plane's cockpit as it encountered an American Reaper drone, at one point coming close enough to make out movements of its propeller. The Russian pilot flew around (top right) the drone, though the encounter shows how close different forces' aircraft are coming over war-torn Syria. On Tuesday the US and Russia signed a memorandum of understanding to prevent clashes and possible crashes in the air, which have been a worry since the latter started a bombing campaign against ISIS and other rebel groups last month (bottom right)
