I can't believe some of the posts blaming the manufacturer, airport, etc.
Spend a few years investigating aviation mishaps, and you will get used to it. "The Other Guy" is a notoriously common cause of mishaps.
Sadly, the swiss cheese analogy contributes to this excusing away of human error.
This is not a statement on the cause of the Asiana mishap, but on the statements being made that led to the quoted post:
Typically most crew, weather, airport and aircraft "frailty" issues are known (or at least available) to the members of the crew prior to push back from the departure gate, and thus should be taken into account as part of their pre-flight preparations. In short, the holes in these slices of cheese are known to the crew, and those slices should be positioned to keep these holes from "lining up" before the aircraft left the ground.
