The crews I have flown behind recently have been Kazakh with a third, Dutch, overseer / training Captain. Whatever their nationalities the lads done good!
I heard, from a chap, who has seen the aircraft, that it was a large flock of seagulls that was hit. There were birds stuck in the undercarriage and red dents on the starboard wing leading edge / slat. Apparently there was a large wing drop and yaw before recovery which suggests, to me at least, that the engine lost a lot of power very quickly. Well done chaps to the crew.
It doesn't bear thinking about what the consequences would have been if they had hit a bigger flock and lost BOTH engines. At least it's very flat and unpopulated around Atyrau airport.........
