  • The latter is definitely true, but the 737 Max is designed unstable not for an increase in manoeuvrability but because Boeing are pushing the envelope of a jet with a basic design which is well over 50 years old.

    The engines on a 737 are close to the ground as it has short landing gear, which is why Boeing had to move them up and forward to provide enough thrust for the 737 Max. If you compare a 737 with an A320 the (much more modern) Airbus has longer landing gear, so Airbus haven't needed to take similar steps for stretched versions of the A320.

    In short, it is much cheaper to improve/modify an existing plane design than to spend billions on designing a brand new aircraft from scratch.

  • Yep. Same with the type approval, it's all about money. And stretching aircraft = more passengers = more fatalities when it does go wrong. Lion Air was the deadliest 737 crash ever.
