The technology behind the problem is interesting. To save the cost of building an entirely new airliner, Boeing took the tried-and-true 737 and updated it. It's amazing to me that they can take such an old design and still make it do wonderful things. Boeing added bigger engines, and that changed the center of gravity on the aircraft and made the nose tend to tip upward. Boeing then did a software design to make the plane stay level - but that made the plane perform unusually in some circumstances.

I've ridden the 737-800 and 737-900, and they were a lot more comfortable than the earlier 737s. I don't think I've been on a MAX. I think the MAX will prove to be an excellent aircraft once the glitches are ironed out - I just hope no more lives are lost before that happens.

Here's an interesting article:
