The ones at fault at the people at the FAA who let Boeing certify their own planes.

[darkpuma]

Both are at fault. The existence of the FAA does not absolve Boeing, their executives or their engineers, of blame.

Everyone involved can share the fault.

Unfortunately, correctly apportioning all of the blame won’t bring back the souls lost.

No, but the whole point in assigning blame and severely punishing people found to be at-fault is to prevent things from happening again.

If we just let these people off scot-free, then you can count on more similar things happening.
