"How one could get into a position where a go-around was deemed necessary (under the CAVOK conditions which prevailed at EICK that day) is totally beyond me".
Well then, I don't think you have thought too deeply about this or perhaps you don't know Cork airport at all?
There is no parallel taxiway between runway 25 and the threshold of runway 35. This means that every aircraft that lands on runway 17 has to backtrack the runway to the intersection (unless they land very short). Therefore, if the previous aircraft takes a long time to get off the runway then a go-around is quite likely to happen.
I have almost had to do this myself on more than one occasion and I don't work for Ryanair.
It would be very nice if someone would give them a nice parallel taxiway for Christmas!
