It turned out I worked in the same building he had, and I found his old office. Word is after he left they locked it up, like a crime scene. I think they were worried his whistleblowing would turn to leaks and I guess they thought his office would have some sort of evidence? It was an interior office so no big loss real estate wise, but that was a super weird chapter.
He was painted as an aluminum bigot but I always wondered.
I used to talk to a coworker about how Mitsubishi - which built the 787 wings (something Boeing has never done before) - had introduced a regional jet and would be coming after a Boeing’s lunch. He was not worried. I’m a little shocked he’s been right so far. In fact that particular division of MHI seems to be defunct as of last February, which is news to me, so I suppose he was right. Maybe the 787 experience was as unpleasant for them as it was for Boeing.
If Boeing did clear it out, they'd be open to charges of doing a coverup. The smart thing to do is lock it up as is.
That everyone survived the collision last week makes be feel better but still not great.
If they were worried about a lawsuit from him they might want to preserve everything in case it was subpoenaed regardless of guilt or innocent - possibly especially if they thought his claims were wrong.
