The Airbus initiated a go around from about one mile out at 1540 local or so so they clearly kept trying to resolve the problem until decision time. It came back around about 20 minutes later, by which every emergency vehicle in Dublin seemed to have converged on the airport.
What was interesting was that normal line traffic kept landing between the missed approach and eventual landing - are they not supposed to keep the runway clear if there is a pending emergency landing or is this only in fuel critical situations?
