The difference is, in the Asiana San Francisco crash was caused by incompetent pilots, from a country, who's educational culture, may have contributed to their incompetence. The UPS Birmingham crash may have been caused, by competent pilots, who made a human error. If you don't think there's a difference, there is no explaining it to you.
A friend's observation over six packs...human error? Well if you wish to sugar coat it. Complacency and a case of skygod teflonism perhaps?
