John Barnett: What were the Boeing whistleblower’s allegations about the airline?

A Boeing whistleblower who raised concerns over the firm’s production standards has been found dead aged 62 in South Carolina.

Local authorities confirmed that they found former Boeing employee Mr Barnett dead in his truck in a hotel car park over the weekend.

Police said it appears he suffered a “self-inflicted” gunshot wound and are investigating further.

Mr Barnett had been giving evidence in a lawsuit against Boeing in recent days, having first blown the whistle on alleged aircraft safety issues in 2019.
