I got some inside info from people at Boeing, who themselves have connections with people who dismantle airplanes and reverse-engineer competitor aircraft. I got a lot of detail - too much for me to type in a post - but it seems that the airplane simply broke up from the turbulence. The rear fuselage of the Airbus 300 broke off from the airplane, accounting for the 30-mile difference between the two debris fields.
To just touch on some of the issues, the load-bearing components of the rear fuselage are made with brittle composite materials, unlike other aircraft that use tougher aluminum. Air-speed sensors - a known problem on the aircraft - failed, and could have sent conflicting data to the aircraft's computer, resulting in full throw of the sensitive rudders. At the very least, this would have made flying the aircraft very difficult, as the plane was flying in manual mode through the thunderstorms. The Airbus line has a history of both multiple rudder losses and a vertical fin and rudder separation from the airframe as was the case in NY with AA. Automated telemetry data received from the aircraft shortly before it broke up showed a failure pattern that is consistent with Boeing's conjecture. The rear fuselage has been retrieved from the ocean. Some experts claim that there is already enough evidence to put together a plausible scenario, and that the black box data would only confirm or serve as a secondary source of evidence.
Nowehere in this discussion did anybody hint at a terrorist act.
