John Barnett, a former Boeing employee who worked for the company for 32 years until his retirement in 2017, died from a \"self-inflicted\" wound on 9 March in the US. Before his death, he had been giving evidence in a whistleblower lawsuit against Boeing, where he raised concerns about production standards, including sub-standard parts being fitted to aircraft and serious problems with oxygen systems on the 787 Dreamliner. Boeing denied his assertions.
