When I passed through NASA Dryden (Edwards AFB) in '69, they were doing some serious research on that, related to deliberate crashing an unmanned aircraft in a controlled way (they didn't wan't an uncontrolled crash, for some reason). I can't find anything from then in my library, but the first reference on the link below may be of relevance.
