Merely a Pawn?
Mr Forkner is certainly not the only culpable Boeing figure, but he is one of them, in my opinion. He complied with the corporate pressures with full knowledge of the design problem and expert understanding of potential consequences.
Every manager and executive that established the business objectives of no additional pilot training and every person who deliberately covered up the need for such bears responsibility and should be made accountable.
Everyone who was replaced and given lucrative severance compensation should be made to forfeit the same.
Fat chance.
