First of all, John Goglia is not the "lead investigator". The IIC (Investigator in Charge) rarely briefs the media. Mr. Goglia is a board member, a politically appointed position. The board members are not investigators at all. However, they are the ones that are assigned, on a rotating basis, to the major accidents to be the point of contact for the public.
Unfortunately, Mr. Goglia has, from the very beginning, been freely offering his "opinions". The NTSB has become the credible agency that it has by dealing in facts. You won't find any investigator, at any level, giving his or her opinion to the media, or anyone else, for that matter.
Hopefully, somone will reel Mr. Goglia in, before he chips away at the credibility of this ongoing investigation, by spouting his "opinions" to the media.
And to jetexas, the NTSB is not empowered to make changes, only recommendations. The FAA is the regulatory agency. The NTSB has made numerous recommendations over the last ten or so years dealing with some of the fatigue factors you cite. Pilot fatigue remains atop the NTSB's "Most Wanted" list. It's the FAA, under constant lobby pressure from the ATA, that is dragging it's feet on initiating long overdue changes.
