Re: 737 with new wing, landing gear potential

The point of staying with the 737 is to keep as much as possible, in this case the fuselage, the same not so much for certification (after the MAX fiasco grandfathering will be intensely scrutinized and will be little different from a new design) as for manufacturing and assembly. Boeing is going to...

737 with new wing, landing gear potential

Yes, the 737 is over 50 years old. But the time and money to make a clean-sheet new plane does not seem to be there, and may never be because airlines cannot endure a multi-year period of low production that a new design would almost certainly entail. The A320 is newer but still old technology, and ...

I never believed that Boeing was going to make the old 777F alongside the 777X for long. Different wing, engines, cockpit, and so much more. While the 77F will likely get more orders now that it is the biggest freighter available those orders will not be enough to make a separate line viable.
