John Barnett, a former Boeing quality manager, blew the whistle on safety issues, including defective parts and malfunctioning oxygen systems in the 787 Dreamliner. He faced retaliation from Boeing, leading to his early retirement. Despite some of his claims being validated by FAA investigations, Boeing often denied wrongdoing. Barnett was found dead in March 2024 under suspicious circumstances shortly after testifying against Boeing. https://video.twimg.com/amplify_video/1791917670880759808/vid/avc1/1208x720/A3Tguwl65FefsY0a.mp4?tag=14
