A few points:

- It was not Lauda himself, but a former Lauda Air engineer, who refused to let his family fly on the planes.

- It was the FAA that certified the design, not Boeing; Boeing is the one that designed it in the first place.

- There is no intent here to say that Boeing wasn't responsible, and in fact they rightly got sued for this, but the problem was industry-wide and planes by other manufacturers were found to have the same vulnerability.
