You are a senior radar approach controller. It has been 15 years since you ever saw weather this severe on the Irish Sea. You were instrumental in encouraging the two previous Aer Lingus planes to divert to Cork, but you fully respect the Captains decision always carries more weight, as he has all the situational facts for the given flight at his finger tips. You think diversions are precautionary for safety and the inconvenience to passengers is irrelevant. You are concerned the approaching flight may both experience severe turbulence and eventually be forced to divert if Dublin airport is closed to traffic. You think the co-pilot sounds young and inexperienced.
