John Barnett had worked for Boeing for 32 years, until his retirement in 2017.
In the days before his death, he had been giving evidence in a whistleblower lawsuit against the company.
Boeing said it was saddened to hear of Mr Barnett’s passing. The Charleston County coroner confirmed his death to the BBC on Monday.
It said the 62-year-old had died from a “self-inflicted” wound on 9 March and police were investigating.
Right, the chart is far from perfect, but they just grouped them both under the “we have questions” section. We have lots of unresolved questions about Epstein’s death, we have lots of unresolved questions about UFO sightings.
No, I understand we have questions but explaining epstein requires a couple of details, while UFOs require new laws of physics.
