Yes, they are not saying if the Loss of all Generators checklist was activated. However, with 15 minutes on finals prior to landing it was probably the best decision to continue on standby power, supplied by the battery. Since the 1&2 GCUs, No1 BPCU and the 3&4 GCUs & No.2 BPCU are widely seperated at oppsite ends of the top shelf of the E rack, it is unlikely that power could not have been restored to at least two generators, providing the SSB (split system breaker) remained open. Therefore the hypothesis of impending disaster of a similar failure over the Pacific, may not necessarily be a valid observation.
