Granted fatigue could have been a factor but I think they had 2 crews which should have given them adequate rest. The auto pilot will not couple to an inoperative ILS. Red flags, all that stuff. Now that could be what delayed their speed reduction with confusion over ILS out of service. What ever it was you can bet there was a lot of scrambling in that cockpit. Another reason to ask for vectors or a holding pattern to sort things out. Not to go barging into the approach unbriefed. The rookie pilot would have had a check pilot “shotgunning” him.

Well no, but this is a very sophisticated aircraft. There were other approaches to the same runway that give precision vertical guidance. Are you aware of any reason not to have been flying one of them?
