15.1 ANU? That's a tailstrike in the A320. I guess some photos should eventually emerge if such damage existed.
The go around initiation seems a bit... delayed? If in gusty conditions I plant it at 2.4g, then plant it again at 3.4g, I don't think I'd wait for the third smackdown to call the quits. Yet it looks like it took them the extra fall from the sky + 5 additional seconds to only take the decision. Should be interesting to hear the CVR...
Everything else after that (deviating with a half broken airplane plus comm failure and what have you) is just covering up the holes made by their earlier decisions (or lack of them). Kudos for covering properly (i.e. not killing/seriously injuring someone) in the end, it seems, but...
Whatever caused the hard touch down and whatever the rights and wrongs of going around, they did a good job in the end
...can't say I fully agree with that statement if such a mess was created by themselves in the first place.
