There has to be some criticism here.
All the talk of short turn-around times is nonsense. It's a fairly direct track from Liverpool to Derry, usually on a radar heading, and I refuse to believe that there wasn't enough time in the (very short) cruise or in the descent to go over the major points of the approach brief.
Also, according to the info here they flew a go-around when the ILS failed/was switched off or whatever happened to it. So why didn't they follow the missed approach, go into the hold, get their bearings and then make a visual approach. They rushed and they weren't ready. Whether this is due to company time pressure or whatever I don't know but the captain should ensure that the don't get sucked into this sort of trap.
If they weren't familiar with the field they should have taken a few minutes extra to ensure they both knew what the plan was. Whilst it's a relatively easy mistake to make, the crew are undoubtedly at fault and have to expect some criticism. Life aint sugar coated you know.
