A is a very good point.
Perhaps, but is a bit humorous at the same time.
If they pay decent world-wages I bet quite a few 'good' pilots would agree to work for them. But without need to push any new laws about foreign pilots working in Russia I don't hear the obvious - send all these 'suspect' pilots from regional airlines to very reputable foreign training facilities, say FlightSafety Int., validate their competency and retrain to FlightSafety standards if necessary. How many of them would even pass a rigorous simulator check ride at FlightSafety?
