I have no idea of the cause of this accident
nor would I disagree that an ILS is safer.
However I would say that this is not a particularly difficult non precision approach,it requires care and dilligence as always ; but anyone who finds it overly difficult has no place in a transport aircraft.
I am concerned that the Media "bandwagon" and the noise abatement lobby, not to mention politicians for their own dubious reasons are casting Rwy 28 approaches as unsafe and potentially hazardous..after all any approach can be challenging ;
with weather usually being the most influential factor.
my sincere condolences to all concerned.
