I'm not yet convinced that I "don't get it", Bloggs. I'm not sure what the regs say in Korea, but in the US the PIC is the "final authority" for the safe conduct of the flight. If I'm insufficiently trained to land the aircraft on a huge patch of runway in near-perfect weather, it's up to me to refuse the flight, isn't it? I agree that there must be huge, systemic problems that contributed to this almost literally unbelievable failure on the part of the flight crew, and I'm 100% in favor of those problems being corrected in a rapid and draconian fashion. But the buck stops with the PIC...or he's no longer the PIC. Down that road (IMHO) lies chaos and MORE carnage, not less.
By all means, if the company culture is poisonous to turning out capable pilots, fix it, yes! But when the camel of "not my fault" finger-pointing gets its nose under the tent, where does it end? The simple fact appears to be that these guys crashed a perfectly functional aircraft trying to execute a maneuver that I used to sign off 10 hour student pilots to do solo. So, maybe there's enough blame to go around?
