True.
But Boeing is the general and responsible. It would be incumbent upon them to go after the Sub who made/subbed/swapped the shoddy part.
Jeesh, I thought people love to sue others?
Unless you are suggesting somebody in the military/government procurement swapped out the good part for shoddy ones and sold the good ones on the black market and pocketed the difference. Yeah I could see that happening here and there. If it is that case then there needs to be investigations, trials and prompt executions.
