John Barnett was an engineer at Boeing for three decades before his retirement in 2017. He raised quality control issues internally at Boeing. After his retirement, he began to give interviews describing the shortcuts that Boeing was taking.
Boeing has been hit with numerous failures of its airplanes. A door panel flew off a Boeing 737 Max 9 on January 5th. A cracked in a cockpit window caused an emergency landing. And a 757 lost its front tire in January.
Barnett’s body was found in his pickup truck at a hotel parking lot on March 9th.
