Even though the investigation into this accident is ongoing, I must say that I agree with all of your postings regarding the probable tail seperation.
After AA lost a DC10 in ORD in 1979 the entire fleet was grounded worldwide to check engine pylon bolts. Given this catastrophe, with structural failure the probable cause, I think FAA and JAA should consider grounding all A300-600 and A310 aircraft until proper checks have been made.
