Tom - At the time of the Ryanair 98MS go-around, there was the slight problem of a Monarch B752 clogging up the runway. Visibility at the time was definitely not a contributory factor.
In fairness to the Monarch crew, they offered to turn off at the intersection and enter the ramp via Bravo, but tower instructed them to continue to Charlie as Bravo is not permitted for their size aircraft (something to do with engines over-hanging the edge of the taxiway).
That parallel taxiway would have come into its own on Sunday afternoon.
The Falcon 50 crew was not "told that they can return to Cork tomorrow"; they had arranged to go to Shannon, and were only requesting a return to Cork at that stage. They were making arrangements for their apparently unplanned return, but they were not, however, being told to get lost until tomorrow.
It is very rare now that one hears bizjets positioning out to Farranfore or Shannon for an overnight. The situation has improved greatly over the past year.
