"Whether you like it or not - that layer of cheese would have prevented this accident"
You have now placed yourself in the same league as the aviation experts on TV that had figured out the cause before the flames were out. Making a declarative statement like that minus all the facts allows one conclusion, and it's not about the crash.
Amazing every large aircraft that lands RWY 27 at KSAN doesn't crash as well seeing as there's no GS on that runway either. KORD 14R is minus a GS as well, haven't read of anyone crashing there as well due to it.
If my small jet has the capability to build a course and slope to a runway (via the FMS) I have to believe the 777 does as well. There are ways to mitigate the threat presented by an inop ILS.
