On a side note, I read an interesting article in the November 22nd edition of Aviation Week & Space Technology that said:
1. The C919 is definitely overweight, i.e., for a "clean-sheet design," it's at the same weight the Airbus 320 was when it was introduced in the 1980s.
2. They've only received no more than fifty (50) confirmed order AND options for the C919, when, in fact, they expected the domestic airlines of China to order two or three hundred of this aircraft.
Unless Beijeng holds a gun to the head of the Chinese airline executives (they will) to force the purchase of huge quantities of this "new, but not overly competitive" aircraft, it will fail miserably.
