In case Boeing misses a December 27 deadline, the company is facing a multibillion-dollar redesign of the 737-flight deck as well as further delivery delays for its two Max models. The company's CEO Dave Calhoun said Boeing could abolish plans to produce Max 10 if Congress doesn't grant an extension to the deadline. The Seattle Times first reported details of Cantwell's proposal. Boeing shares are up 1.5% in pre-open Wednesday.
