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.
Speechless I am, Sir !
The difference between a crash caused by a competent crew that made an error and an incompetent crew that made an error finally explained! In remarkably few words! Should there be a vacancy at the head of the Flat Earth Society, you can count on my support
