As Friedman would point out, we already have an agency that answers to the public in charge of aircraft safety. We have volumes of FARS, CFRS and other regulations and laws on the books. Those regulations were ignored and/or at least massaged to get around key aspects of those regulations.
Perhaps a dozen or so new regulations and a new agency, with a the caveat *Hey, we really, really mean it this time?
The market will always speak first and the loudest: I will never fly Boeing again.
