I think CEJM has very little idea of what the job of a 777 pilot in a carrier like Asiana, Korean, CX, Quantas, ANZ, etc is like. Arfur's last paragraph sums it up very well.
Yes, there's no excuse for crashing a serviceable aircraft on a nice day into a long runway, but there are some mighty large contributing factors. SFO ATC need to take a good long look at the way they operate, having drilled at least 3 very large holes into at least 3 Swiss cheeses on the way to this accident. Likewise JFK, although they at least seem to be getting the message and have been sprinkling some PAPIs around their more troublesome runways recently.
The FAA are stepping in because it's been business as usual since the accident so someone has to, and those that should be effecting change aren't.
