These guys may have been saved by NVG but it's impossible to make that assumption.
If you were doing this letdown during daytime in the same weather (300-500' cloudbase and 2 nm vis) you would be looking out of the window once below cloud at 200'.
If you were doing this letdown in the same weather at night using NVG, you would be looking out of the window once at 200' - with 2nm vis, how would you not see a nearly 300' high lump of rock with a lighthouse on it?
I still feel that procedural/behavioural influences were a big factor as was automation bias.
Absolutely right - because they had no NVG and the procedural let down was all they had. Could that have been executed better? Possibly.
