I'm not familiar with this type, but with the 737NG right now.
Is it the case that, following the realization that a flapless landing will be necessary, that the crew cannot disable the "TO LOW FLAP" GPWS aural warning?
This is 'normally' done during the non-normal checklist as a result of the malfunction, is it not?
I would bet that, had the "TO LOW FLAP" GPWS warning been inhibited, the gear warning "TO LOW GEAR" would have been the trigger to do something!
Simply because, having inhibited the flap warning within the checklist, they would not have expected any warnings, and that warning aural may have woken them up to the oversight!
....or get a flight engineer!
