I'll probably get caned for this post, not being a pilot, and being Australian. I find that the culture of deference to "authority" in Asian countries leads to groupthink. The PIC in this case was a consensus not a person, between four people, none of whom could take responsibility for landing the plane. Nobody was in charge. An amalgam of experience and rank all sitting like muppets having to land the plane with their own anxious inputs at certain points, leading to disaster. It wasn't a difficult day, airport or plane. Just four pilots, none of whom was willing to take command early enough. The Cabin staff probably would have done a better job, or a sixteen year old on a computer.
