China’s C919 commercial jet aspirations are overblown and no threat to Boeing or Airbus

Chinese locomotives are in use in many parts of the world. and the capability to envision and improve this level of manufacturing suggests to me that COMAC could assemble western components into a recognizable jet liner. Boeing has allowed final assembly to be completed in China, so the chinese know from the inside-out what a proper airliner is to look like.Chinese cargo conversions are being completed , giving them further insights into design and manufacturing. Unless the west prevents needed components from export to china, COMAC will have all the parts, few of which they built and developed, making them an assembler from components at local labor rates. Quality and reliability and customer confidence are not export items however.As a state enterprise, profit/loss and export achievements are viewed under a Chinese governmental calculus.
