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.

Totally unrelated to the Boeing that lost a wheel last week or the Boeing that had "a strong movement" today, injuring 50.
