A self-described “family friend” said that the Boeing whistleblower (1 of 60?) said that. Also, as anyone who works with mental patients can attest to, “if I die, I didn’t commit suicide” is not anywhere close to as ironclad as it sounds on the surface… (I.e. 99% of those claims were false)
I'd recommend doing cursory research before confidently claiming something as fact on the world wide web.
I learned about the dangers of spreading rumors from Veggie Tales when I was five. We all make mistakes, but there's really no excuse for peddling secondhand information when established facts are an internet search away at all times.
