No details of the routing, just that it is planned be a non-stop flight. BHX airspace is on the direct track, so route could be either south over Welsh mountains if weather permits, or north along N Wales to Holyhead. By my reckoning that could mean landfall anywhere between Arklow and Dublin. This is all pure guesswork, I think conditions on the day will determine everything so the only source of info may be via ATC or a Scanner. The backup team will be in GWY, so maybe ATC at EICM will have up to date info.
