A investigative authority like the NTSB is a really interesting idea. If it had the authority to level fines against companies that have been negligent or acted without due care it might have a real effect on behavior.

The only current recourse for those affected by these sorts of incidents is class action suits or public outrage/reputation damage. Both of these seem limited and put the onus on those who are impacted to fight for recompense.
