The tragedies of Flights AA 903, AA 587 and AF 447

I have no business taking part in the speculation furore over the probable causes of the crash of AF447. The experts will study the bits and pieces recovered both from the wreck site as well as from the automated messages and hopefully, succeed in providing the answers that victims’ families, passengers and airline operators want.
They may perhaps consider going through the Aircraft's design and specifications, with particular attention to the incidents of flights American Airlines 903 of 12th May 1997, 587 of 12th November 2001 and see if these could match up with that of AF 447 of 31st May 2009. That’s where I could throw in my 2-bits worth!

Both AA flights encountered turbulences that compromised flight and control.

AA flight 903 managed to land safely. Subsequent investigation seemed to indicate that at some point, tail-fin failure could have occurred.
AA flight 587 apparently ran into severe wake turbulence shortly after take-off, had a tail-fin break–up from crew desperately trying to regain control and crashed with loss of all 280+ lives on board plus 5 ground fatalities.

There seems to be consensus that AF 447 ran into heavy turbulence just before it crashed.

Two images seem to point to the horrifying similarities between the AA flight 587 and AF 447:

Could AF447 have suffered a catastrophic tail-fin failure, notwithstanding the precipitating factor of the pitot tube/ sensors icing over? Speculate: Initial loss of flight control as auto-pilot is automatically switched off, crew frantically struggles to regain control, pressure applied on tail-fin rudder pushes it to beyond theoretical design limits, tail-fin failure, bulkhead pressure dome compromised as tail-fin breaks away, cabin explosive decompression and hull disintegration……Hey! I am just a layman who should perhaps do best to keep his nose away from where he has no business sticking it in! And that’s the truth! No need to point any artillery at me!
