The 737 is a design from the 60s that has been milked over and over again. It was originally meant as a regional jet yet today it’s being used for midrange and sometimes even long range flights. It’s being placed in roles it was never designed for so the whole thing is kind of a Frankenstein design today. Take the engines for example. Today’s engines are much bigger than those from the 60s so they don’t really fit underneath the wings anymore. So they place them in front of the wings, changing the center of mass. That imbalance is then compensated artificially with MCAS. Needless to say, that’s not ideal but it was cheaper for Boeing so here we go.
The issue is mass shootings have become a part of American culture. Americans not only like killing brown people in other countries, but also themselves. I’m obviously overgeneralizing but it does hold true to at least some degree. The only real solution is a mass reeducation of Americans and that can only happen once the US itself is thrown into the dustbin of history.
