Indeed, Blacksod, 10nm east, was. But the question still remains as to why the crew thought being at 200ft in poor vis at night, for a 10nm approach to Blacksod, was the best method.
Absolutely - that was my point about the lazy use of an old S-61 procedure which they weren't really familiar with but followed, apparently without thinking, when a simple self-positioning radar letdown, much closer to Blacksod would have been far easier and safer.
