Why do we have the domestically produced C919 and still need to buy Boeing planes? A US delegation comes, has a meal, and leaves, yet we still purchased hundreds of their Boeing aircraft. Why not use our own C919 big planes? The thing is, our C919 currently has insufficient production capacity, and many routes aren't compatible. Domestic airlines can’t afford to stagnate, so we need to buy Boeing planes as a buffer while we keep our heads down and develop our domestic aircraft. 👍 $BTC
