Boeing whistleblower John Barnett found dead days after testifying against company

John Barnett, 62, worked for Boeing for three decades and retired in 2017

The whistleblower who publicly raised doubts about Boeing's production standards was found dead.

The Charleston County Coroner's Office told Fox News Digital that John Barnett, 62, died from what appeared to be a self-inflicted gunshot wound on Saturday. Barnett was cross-examined by Boeing's lawyers and his own attorney days before he died.

The court planned for Barnett to answer more questions on Saturday, but he did not appear as planned. 

The BBC reported that he was later found dead in his truck, which was parked in a hotel parking garage.

Barnett was employed by Boeing for over three decades before retiring in 2017. He worked as a quality control engineer at the company. 

In 2019, Barnett told the BBC that Boeing would rush to get its 787 Dreamliner jets off the production line, compromising safety.  

He alleged the emergency oxygen systems that were made for 787 Dreamliners had a failure rate of 25%. This meant that a quarter of 787 Dreamliners had the potential to rapidly lose oxygen if the cabins were suddenly decompressed, suffocating passengers.

Barnett said that he had encountered these issues when he began working at Boeing's North Charleston plant in 2010. He reportedly raised his concerns to his managers, but did not see them take any action.

The Federal Aviation Administration reviewed Boeing in 2017 and ordered the company to take action, which corroborated some of Barnett's allegations.

This past January, Barnett told TMZ he was concerned that Boeing was returning its 737 Max 9 jets to the sky too quickly, after the incident in which an Alaska Airlines jet's door panel blew off midflight.

Boeing told FOX Business that the company was saddened by Barnett's death.

"We are saddened by Mr. Barnett’s passing, and our thoughts are with his family and friends," Boeing's statement read.
