Will this deter further speculation about terrorist involvement in American Airlines Flight 587 crash?

There has been speculation on the internet that the plane which crashed in November 2001 within minutes of takeoff from JFK had been the target of sabotage. Observers have found it suspicious that the entire tail assembly, not just the ruddder (the fin that moves left and right at the rear edge of the tail), had come off and fallen in the bay at the end of the runway a mile or so before the plane came down on an ocean shore neighborhood of Queens.

Co-pilot Blamed for Crash of Flight 587:
"... Airbus told the NTSB that it included a warning that abrupt rudder movement in some circumstances 'can lead to rapid loss of controlled flight,' and, in others, could break off the tail."

The article also points out that, when re-inspected after the 2001 crash, an Airbus jet which had suffered a severe landing with one fatality in 1997 had serious cracks in the tail assembly.
