Boy, this is true. I flew Aeroflot back in 1993 (from Irkutsk to Khabarovsk in Siberia) and it was a unique and eye-opening experience for those of us who had only experienced Western airlines.
The crew was fine, and there were no incidents, but it seemed every Russian passenger was continually drinking & eating food they had brought on board (very pungent food at that). I remember two gentlemen in the row in front of us, who were well into a bottle of vodka before we even took off. At the point the plane started its takeoff run, there was an announcement and these two leisurely put their bottle up, put up their trays, and brought their seat backs up. Literally seconds after they had completed all of this, the plane lifted off - at which point IMMEDIATELY the seats went back, the trays came down, and the vodka came back out.
aeroflot has the orst safety record of ANYONE. In fact, I think I could kill fewer people while operating an airline consisting of rollerskates with wings and rocketpacks on them.
I have a friend who was working with the Russians on their joint venture with Lockheed. He had the best horror stories, even if he made up half the stuff up. The flights smelled of vomit; when he got to the launch site they needed half tracks to get there through the mud. Armed guards if he ever left....fun place!
