A part of me says that it’s entirely reasonable that a guy who worked for Boeing and likely signed off on thousands of defective parts would feel a brutal surge of guilt after giving testimony about it. I can’t imagine the guilt if I thought I had potentially hundreds of people’s blood on my hands. We don’t know if he was or felt he was responsible for the deaths caused by MCAS or other tragedies. Maybe saying it out loud brought all of it back and he felt like he needed an out.

Another, louder part of me, says that Boeing either pressured him into committing suicide, or shot him themselves to stop him from revealing too much damaging information.

Another part of me remembers that Malaysia Flight 370 was a Boeing plane that disappeared by essentially cutting all communications and flying back towards the mainland. Knowing now what we do about how Boeing has been run, I think the most likely thing is that some serious technical issues happened to that plane, the pilots tried to return back but were unable to control the plane long enough, probably due to being unconscious or dead, and it eventually crashed into the ocean.
