The Boeing boys are obviously all right, no Boeing has ever had a hard landing!
1 out of a bezillion Airbus approaches results in a hard landing and the design is all wrong. They walked away, no one hurt and the aircraft may need a gear change.
First, how do we know the Autothrust had anything to do with it? After all if it is gusty, you could always add a few knots on if it were required.
Second, I think the Autothrust response was a tad better than the BA777! I know, lets blame fuel iciing whilst we await to find out what happened.
