If the crew were letting down to Blackrock to get visual underneath then the track they took seems reasonable for a straight in approach into wind (based on the info from the map from a previous post. Now, looking at that map, they appear to have gone around to the north-west, either because they didn't have sufficient visual references or because of a technical problem (which we still don't know at this stage of course).
What is puzzling me is why they took a left turn back towards Blackrock downwind & possibly low level especially at night? If the cloud base was 300-400ft & the lighthouse being 300ft above sea level on blackrock then there was a chance they wouldn't have seen it from the last known position just short of the island. Could it have been a case of being in a very vulnerable position, i.e; Vortex Ring? low forward indicated airspeed with a tail wind descending towards a very big wall of rocks & realising what was going on but then being too late when trying to pull power - too close to the ground?
Or some sort of technical problem either at a similar time of potential Vortex ring state (which would be extremely unfortunate) or from the initial go-around worsening?
RIP to such a talented & experienced crew... very sad time for all
