Obama,
Don't think anybody is missing the point here, we know from the CVR they had a "Control issue" and elected to abort. What that issue was is presently unknown and hence a source of conjecture.
Likewise the overrun, given the presumably light take-off weight of the aircraft and seemingly more than adequate runway length and overrun area which was almost double the required BFL naturally causes one to wonder if there was another failure that caused the overrun, although as I posted previously I now think the overrun was purely a result of the very late, high speed abort.
