There appears to be a drift away from the subject in hand here.
Let's put it bluntly, that this crew messed up big time and were lucky to walk away from it unscathed; forget there not being an ILS and all the NOTAMS. What were they doing allowing themselves to get into such a dangerous and unstable position. The Capt seems pretty experienced on type, and the FO was not so much so on type, but had a significant number of hours. When one of them saw that they were digging a hole for themselves, they should have gone-around and not persevered putting the lives of those who trust in them at risk.
This crew should be ashamed of themselves.
