TAWS Saves
is an excellent document.

"...but did the aircraft have the obstacle database option enabled?"

It's installed and I don't believe it can be disabled (turned off).

westhawk;

" Had the airplane gotten much lower that far from the runway a terrain warning would presumably have been generated."

The Terrain Clearance Floor (TCF) is, I believe, "standard" - 700', then from 15nm to 12nm the warning area descends to 400' and then at 4nm it descends to the airport level at between 1/2 and 2nm. The warnings would be for both terrain and obstacles.
