This will make you not want to fly for a little while. It’s footage of a Tupelov
Tu-154 airliner struggling to stay aloft amidst severe oscillations. It’s downright scary to watch. This was apparently the plane’s first flight after emerging from long term storage at an air base outside of Moscow. Well done to the pilots who eventually landed the plane safely.
Severe is an understatement. Be patient, the camera man doesn't 'lock' on to his 'target' until 42 secs into video.
