In 104 pages, this is the first post that's made me think "hey, that might be something." If I remember correctly, the AA in Cali featured an FMS input of an identifier that was not the intended waypoint and it commanded a turn off the correct flightpath. While I doubt an erroneous FMS input was the cause of this crash (not much CFIT at FL350!), it's a good hint at a plausible answer to one of the many, many unanswered questions we all still have.
