Easily preventable, it just takes money. Good IFR instruments and a
rated pilot would take care of it.

The new GPS terrain aware maps, and terrain view horizions, would have
prevented it easily. But they aren't cheap.

You should offer your services to the NTSB since you know the reason for
this accident without even seeing the aircraft or knowing anything else
about the circumstances.
