2ndly, a state-owned airline in China doesn't mean that government would cover its losses. Such thing indeed happened in Chairman Mao's time but not today, not after Deng Xiaoping's era. Otherwise China would have not jobless men because government would order state-owned companies hiring them all and communism would have been achieved tomorrow, or most likely, Gordon Chang would have become the greatest fortune teller in human history.
Did I ever write that the Chinese government will cover the losses of airliners?
1stly, Chinese government worries C919 crash more than how many planes have been produced. Such prudence contributes a lot of C909/919's low utilization rates, but also contributes lots to their zero major accident record after all these yeas in service.
