Runway overruns are almost always as a result of poor piloting skills.
The nosewheel failure looks like a metal fatigue issue. One plane was 16 and the other 35+ years old. Long before Boeing's current C-Suite and management moved to Chicago to become stock market share price engineers rather than aeronautical engineers.
I still fly Boeings and trust them generally, but they better turn things around fundamentally, or they will get sued iinto Chapter 11 and/or lose more sales to Airbus and Embraer.
It's not that hard. I imagine there are a few, very few, key people who are stubborn and are getting in the way. Boeing's Board needs to provide hard, cold demands to put quality FIRST at any cost, including firiing anyone who gets in the way of that.
