I was on LH480 MUC-DEN on 9/11. The plane was an Airbus 340-600.
Upon landing, we made very hard contact with the runway and then took off again.
The pilot came on after a few minutes and mentioned that something felt unstable because of the wind, so they decided to abort the landing.
I have been on a few go-arounds, but never after contact with the runway. I assume we "managed" to touch down due to a delay associated with engines spooling up?
