six years fying in/out russia every week, I can tell you how much these guys can drink. I still remember my first night in Moscow.
F/A I have had flying with me came from different companies and toasting with Vodka for a save flight was item 1 before starting engines on the QRH and last item before leaving the aircraft. "Russian Standard" SOPīs.
BTW, all ex USSR countries share the same way of thinking and I still canīt get it.
