Read the response from Aeroflot in the comments under the video on youtube, says it all.
Many local Capt's operating in airlines in the former Soviet Bloc still seem to think this is OK. It is fine when there is a Scandi FO sitting next to him who has the cojones to say, "Er sorry Vlad, this isn't on", but with 2 of them up front
If I was in the back (well, with Aeroflot I wouldn't be anyhow
) I would make enough fuss (once we taxied past any remote de-icing available) sufficient enough to be thrown off, up to & including opening an exit/blowing a slide, I kid you not.
No way to have your life snuffed out by these reckless vodka-guzzling bar-stewards.
