I'm quite appauled having landed wheels up a pilot would then elect to do a go round.
No sorry gents there's no rational argument for this one!
Once an aircraft is down it stays down particularly if like in this case (And we can obviously only go and react to the facts presented here) If a landing results in contact with the ground with parts other than designed to.
My own experience literally post Falklands campaign a rather experienced Harrier jet jockey in front of the whole station along with various nations dignitaries came into land an promptly forgot to put the wheels down (No he did really! No technicalities he forgot!) he then promplty selected the nozzles down and initiated a short take off recovery knowing full well the aircraft had made contact with the ground.
All praise he brought it back safely but!!!! it was down and out and had travelled several hundred metres on its Aden cannon pods! with luckily very little other damage.
It could have been different of course!
