The accident flight descended into hostile terrain at night and had a CFIT. That has less to do with GPS jamming than it does accepting a visual approach from 14 miles out with an enormous mountain they couldn't see between them and the airport. The error as I see it is abandoning the safeguards of flying a standard instrument approach procure. RNAV or ILS, the terrain clearance is backed into the procedure. They descended below minimum safe altitude.
