I’ll find the specific passage but the pilots made a wrong turn *after* GPS was turned back on and they had claimed to have their bearings. The fact that it was a moonless night with an unmarked airfield in mountainous terrain was by far the most influential factors with what happened
White Sands started it back up, and in which you had a controlled flight into terrain. This is the overall flight path with the key communications, and you can see the flight crew started doing a left hand with GPS back on rather than wait for a right hand for ILS line up.
