After having flown the Pacific for a whole career, as well as known the extraordinary terrific capability of RNP and GLS/GBAS, to always provide a safe path to take a jet to the runway TDZ,... always (not even considering supporting LAND2 or LAND3 or DUAL, or AIII), ...and how easy it would have been to implement both RNP and GLS/GBAS at PTKK (just like CAL once tried), it's unthinkable to me why we are still are incurring unnecessary hull losses like this, even if there is an unexpected loss of visual reference, or CB induced windshear.
PS. Thank goodness for the B737. It's one tough bird.
