I just saw the videos for the first time. A total non-event, hyped up by clueless spotters who think they know more about handling a big jet than professional pilots. The landing was firm, as it should be in those circumstances.
I can imagine how a spotter would mistake this for a hard landing, but what I can't understand is the arrogance by which the opinions of experts like Rainboe and Dan Winterland are dismissed by some people in this thread (and similar threads in other forums). To those spotters, I can only say: please don't step on board of my B777 if your destination has a short or narrow runway and there's a strong wind in the forecast. I promise you, I will plant it on the concrete like that A380. You may prefer an elegant landing over a safe one, but I surely don't.
