I've got some sympathy for the Korean crew going through this ordeal. The pilot flying, I think, is responsible, and to a lesser extent, the pilot not flying. They both have hell to pay, as they should. That's how the system works. But haven't we all screwed up from time to time, but just had the luck, common sense, or help to recover in time, before it became an incident?
I have, or did, in my 42 year career of flying, I'd be a poor liar if I said otherwise. 'There but for the grace of God, go I...'
