This video makes me sick!!!
i hope you forward your flight NR ,date, all details to the Civil aviation in Russia,and the press.
I hope they are banned to fly for life!
I actually contacted this airline and their reply was (apparently signed by deputy director of operations and director of air safety) "There is no violation - snow has been blown off instantly [ not actually instantly, and not completely - my remark ] and therefore definitely didn't affect aerodynamics and safety" (That's almost their exact wording, translated from russian language).
Please keep the operator's reply and send it to the Russian CAA along with YOUR country CAA.
If yo have the details of the flight ,please PM them to me.
