This was such sad news, and my heart goes out to those that lost family and friends, its funny to hear how many planes have gone down this year and it makes one feel unsafe getting on to a plane these days and you would think that with all the technology that we have there shouldn't be some many crashes.

The A300-600 series aircraft was that of American Airlines not US Air and speed is not necessary to create excessive G forces, remember, the aircraft had many discrepancy reports prior to crash and the crew training was unprofessional which helped create an unsafe situation. The Airbus aircraft are Transports not jet fighters and no place for jocks with heavy handed maneuvers. Tail sections and fuselage body areas are made to separate at a certain G Force during a crash sequence to allow for better chance of survival of passengers. If at any time these G Forces are exceeded in flight same will occur regardless of the aircraft manufacturer. Aircraft regardless of size entering into extremely severe storms will and can end up in tragic circumstances as it appears has happened here, the wise thing to have done was circumnavigate the storm or turn around as point of no return had been reached. The maintenance telemetry can and should not be used as a method of figuring out what happened here, without the Flight Data Recorder and/or Cockpit Voice Recorder to compare sequence of events makes this cause of crash speculative at best. I do not have a close up picture of the hookup segments and pins to see if its in tact or sheared off and did notice that there is no rudder. Tail should be composite and should float.

An Airbus A320-232 registered D-AXLA operated by XL Airways (Germany) crashed during a test flight on 27 November 2008 off the coast of Canet-Plage (66-France).

This is an indicator that it separated in flight and not on impact. It is interesting to note that the vertical stabilizer separated from an US Airways Airbus Industries A300-605R on take-off in 2001 at JFK killing all aboard. The cause was determined to be (in part) improper rudder input by the co-pilot while dealing with wake turbulence. As a pilot, it’s seems inconceivable that a passenger aircraft whose vertical stabilizer could separate at the connection point in turbulence would be certified as safe. Especially when one considers that in the JFK incident the Airbus was flying under 250 knots, more or less straight and level and the pilot’s only error was excessive rudder input.
