The Senate Committee report, IIRC, supported, via the statements of KSM, that Moussaoui was not part of the 9/11 crew, but was maybe for a "second wave" attack.
A curiosity (maybe not so curious) of the report was selection of statements by KSM that he was too bush with 9/11 plans to deal with later actions - then the Afghan invasion messed up things for AQ...which led me to ask the question "So what?" What was the idea of the second wave plan of attack? Cropdusters perhaps?
