From the video of the wing from inside the plane the touchdown was not that hard, which suggests he had decided to go around well before it 'landed'.
SLF, but I've been in planes that landed with no drama when the wing was working much harder than that on the approach - and enjoyed the marriage of engineering and art that makes it possible.
I thought that a late go-around could result in a touch and go simply because it takes time for the engines to spool up and develop thrust?
