Within the Interview Summaries, in the reports linked by Airbubba, is this snippet from the Captain under training in the left seat, Lee Kang Kuk:
He began preparing for the flight at 0930. It was a training flight, so he showed up early. The cockpit crew show time was 1510. He spent almost 6 hours preparing for the flight, checking the NOTAMS, the regulations, and the ETOPS
regulations. He first saw the PM (the instructor pilot) around 1440. He briefed everything with him. Pushback time was about 1630 local time.
Turning up at work "almost 6 hours" before report? Dedication ..... or extreme anxiety?
Furthermore, from the Jazz Hands post above, it seems the culture authority gradient idea about who can and cannot instigate/order a go around does not sit well with a safe operation.
