Also, your map on the ND would not coincide with your presumed position according to the glideslope.
I have never heard about such an occurence.
Me neither.... But.... Trying to capture the G/s from above in a B744 is really NOT a good idea. The GPWS will only give a 'Pull Up' if you are BELOW the glideslope. If you are still above the G/s trying to capture it from above there is no warning provided the aircraft is in the landing config. A crew that attempts to capture from above then fails to notice the lack of G/s capture, carrying on in V/s to 100' RA is in big trouble. My guess is that's what happened.
The Enhanced GPWS will call-out to trap an off-field landing but the 'safe-zone' around any airfield is not related to the selected runway in the FMC so the area around the threshold of FRU08 is also a 'safe-zone'...... Food for thought.
