I've seen this before, many times. "They tumble and roll and dig a big hole"... except they don't sometimes. The AI pilot screws up his forced landing, sheds his wings, tail and a whole lot of other junk and then the empty, shot up, dented fuselage comes to a stop and starts rolling over and over without blowing up. It's kind of silly, but they always eventually blow up in my experience, given enough time.
