The problem is not the altitude. The problem is high altitude + hot day + high humidity + low speed (’cause the plane isn’t at 400 knots yet) when taking off. But the real culprit in my mind is the autopilot “feature” that was supposed to correct for pilot errors - much in the same way that several Airbus planes’ autopilots caused or contributed to crashes.

Reminder - the first 737 was flown in 1967, 52 years ago.
The engineers have been updating the design every since.
I recently read that the software (autopilot) was written to compensate for a engineering flaw introduced when they added larger engines to the aircraft then what the original aircraft was designed for.
The new engines changed the way the plane flew.
Perhaps the design for the 737 has finally reached a point it can no longer safely be tweaked.
Perhaps someone with better knowledge could explain it better.
