That would be my take too. While I have to view it with a tinge of skepticism, this guy isn’t a light weight. He may be making his thoughts public to grease the skids...
The truth will out...
He indicted it was from the Boeing info, I suspect he has friends in high places at Boeing from his command days in the AF. He also said the pilots did not turn off their com’s and may have been communicating with someone.
I am not agreeing just repeating what he said.
