As I was researching some Trans Texas stuff on the web to find good pictures of their DC9-14's, I stumbled across an accident they had with one of their CONVAIR 600's. The 600 was a CV-580 but with RR vice Allison turboshaft engines essentially.
These links include the The NTSB accident report, a written transcript of the CVR around the time of the accident, and an actual copy of the CVR sound file.
This was a horrific instance of lost "situational awareness" and the old non-CRM mentality that existed at the time.
I believe the "Page VOR" the Captain refers to is now the RICH MOUNTAIN VOR (PGO), which either replaced it or is in roughly the same area.
Take your time to review all of this - you will hardly believe this could happen, but it did. I will say that flying in the Gulf states area is tough, especially at lower altitudes because of the constant, always changing thunderstorm activity. I lived with it for two tours as a jet instructor at Beeville, Texas,and you really had to have some backup plans in your pocket all the time.
Local area tactical training was not a big issue, but instrument training flights usually included out-and-in flights/practice instrument approaches at various military bases within a 500 nm radius, and things could change in a hurry.
Luckily a jet gives a lot of options in getting around many of them, but the downside is always !!FUEL!! vs alternate destination options.
