Boeing is for sure a shit show and terribly managed, but I don’t think they would blatantly kill guys like that. I think it’s far more likely that the first guy did kill himself because he figured everybody would think Boeing whacked him and that would do far more damage to the company than his testimony would. Now any news falls under a suspicious gaze and here we are thinking some other guys unfortunate death is due to nefarious deeds.
Or I’m wrong and Boeing has a CIA division ¯\_(ツ)_/¯
Really? Let me introduce you to the Firestone Tire Controversy, where executives knew their tires were responsible in the auto accident deaths; they calculated the cost of doing a recall was more expensive than paying out compensation to families and decided to not do a recall, resulting in even more deaths - until they were finally found out.
Companies will abso-fucking-lutely murder and let/or let people die preventable deaths for profits. Sometimes, executives even go to prison for it (3 confirmed deaths in that case).
I don’t know about the Boeing cases, but I do know you’re naïve if you think executives won’t murder people for profits.
