I have not heard what approach KAL801 was flying. Guam International has
several approaches.  Field elevation is 297'; runway 6L touchdown zone
elevation is 256'.'
The ILS (NOTAMed out?) has a decision height of 456'.  The minimum
descent altitude (MDA) for the localizer only approach is 560'.  The
VOR/DME approach has a 660' MDA with the missed approach point 2.5 miles
past the UNZ vortac and  .8 short of the threshold for 6L.  The UNZ
vortac is at 680' MSL.
Since the impact site was close to the vortac, one news report
speculated that the pilot was looking for a zero DME reading for the
threshold which would put him at the 660' MDA over the vortac.  (The
vortac at Kimpo Airfield in Seoul is at midifeld.)
Another report implied he was flying the VOR approach which has an 860'
MDA.
