Thanks for the insight; I lost an old mucker of mine in this crash, and always wondered why the Radar had not been used to avoid the hill. I'm not familiar with the AN/APS 20, but would have thought that it would still see the radar shadow (cutoff) from the hill. Its not the first time that 'new brooms' have ignored hard won experience; sad that in this case it appears to be a major contribution to the accident.
