Two more Boeing whistleblowers have come forward amid allegations of incompetence and cover-ups at the company following the deaths of two previous whistleblowers.

Roy Irvin and Santiago Paredes have joined other whistleblowers in sounding the alarm on safety problems at Boeing, with the two sharing their concerns with the New York Post. They allege that the company is fully aware of safety problems and not only refuses to address them, but retaliates against employees who try to sound the alarm.
