Sounds to me like we can either start applying some common sense to our personal management of rest and fatigue or wind up with more "solutions" thru regulation. The same regulating that allows 24 hour duty days with double crews on ultra long-haul.
I still don't think this was a fatigue driven event, as much as it was lack of training and inexperience. Either way the Media/Feds/Capitol Hill have gotten a hold of it, and the circus has begun.
There will be something coming out of this.
