Greybeard,
"the 260 knots at 700 feet over the ocean, the latitude and longitude..."
Now there is an interesting bit of information, of course it makes sense when the impact point was 1560ft after reacting to the GPWS. but don't think I have ever seen 700ft published before in any of the literature I have perused.
" With this evidence that the airplane had performed exactly as programmed, there was no point trying to blame the DC-10, McDonnell Douglas, Collins Avionics, or Litton, the maker of the Inertial Sensor Units."
Would you know if this information was available to Justice Mahon, or to the Accident investigator Ron Chippendale??.
