Joe mentioned the bigger engines creating the original problem which they 'cured' by software. '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'
Doesn't get a wide mention. Hard to know what to believe these days but as they are being allowed to fly again I've heard nothing about the engines, only new software.
So do we now rely on software to make things fly that shouldn't?
