Considering many, many aircraft used this approach and after, that same night, and did not try to land on the TWY......according to the drivers, they did not do anything wrong, just did a GA because "something didnt seem right"
The Asiana 214 crash at SFO happened in part due to a misunderstanding of a peculiar way the 777 Auto-Throttle worked in a set of circumstances the NTSB described as "very rare" -- after all, many many aircraft use auto-throttles on approaches all the time, without issue.
However, only
after the accident did we start to look for other times crews made the same mistake. By analyzing historical FOQA data, one US airline reported that in their fleet pilots made the same mistake several times a day! Another US airline found seven instances that the same misunderstanding almost led to accidents, including one where the approach speed had deteriorated to almost 20 kts below Vref.
So while the vast majority of A/T approaches were incident free, mistakes were happening. An accident like Asiana 214 was just a matter of time, and likely could have happened to almost any 777 operator. The Asiana crew were simply the unlucky ones.
Similarly, in my view, through this AC759 incident we will find out many similar cases at SFO and/or other airports which had not been reported before. That many aircraft used the same night visual approach successfully that has no bearing to the fact that there might be an underlying cause such that a serious incident like this one might have been inevitable over time. Hence it's important for us to understand it, so we may try to prevent future occurrences.
