Very well executed Balked-Landing, good training paid off and prevented a catastrophic situation.
I don't agree with the "prevented a catastrophic situation". Look at the pictures of the damaged wingtip. It was very very unsure that the aileron wasn't damaged or jammed, and in case of a go around in such a windy day, I'm not sure the plane would have flown very far.
It already happened in the past, and had a bad ending.
They were lucky, that's all I can say.
