I shot these TU-154s when leaving Beijing last July. Stark contrast between the gleaming, modern international terminal, the brand new Boeing and Airbus planes used by the Chinese domestic carriers, and these two junkers. Although from the descriptions I've read, Air Koryo is still better than many African or Latin American airlines - the flight attendants are pretty, the food is somewhat palatable, and they operate (sort of) on time.
But I suppose if they had a domestic flight crash every day, we would never hear about it...
