I seem to recall that most of the damage done to the Tristar was from the second bounce and not the first impact from the "auto land".
Indeed it was a failure to understand the automation, which lead to the initial impact. The failure to correctly hand fly the recovery, as a result of a failure to understand the flight control system caused the more serious structural damage.
Not a great day in the office for the guys at the front end.
The TriStar autoland system was fantastic and very capable, indeed many described it as PFM. The weak link in the chain was the aircrew that had inadequate knowledge, training or hand flying skills to meet the challenges they gave themselves that day.
