Somebody like "ExPonent, Failure Analysis Associates", in Menlo Park, California.
Or RTCA, who published strict rules for Lithium Ion Batteries, which Boeing then completely ignored, relying instead on their own in house generated "special conditions".....Which they then failed completely, because the authority, FAA, allowed them to certify themselves?
But certainly a private and independent entity, some one who is not paid by the people who compose their mission statement....(Congress).
Who would you choose? Some one who receives Lobby Money, or someone who is paid out of independently managed and scrutinized funds? Subject to independent Grand Jury Audit, at random?
May I submit for the approval of the assembly the most egregious and flagrant "OXYMORON" known to mankind?
"CONGRESSIONAL OVERSIGHT"
