Well Kraz of course your end of things won't usually have any issues re human remains on board - they're not self-loading and rarely complain. But the people in the silver suits with the big squirty trucks might need to make a crucial distinction there at some point. Like when they're rapidly counting the sodden, singed people lying groaning (or extremely quietly) in or around what used to be your airplane to see if everybody who's anybody is out, or at least somewhat accounted for. Or when those guys with the rubber gloves have to scene-match some odds 'n ends, to see if what they're holding flew there in a seat or in a long box.
That'll determine the type of phone call they might need to make very soon. Useful information, somebody has to think about all that stuff. (And there's always the possibility of that annoying situation discussed in my sig.)
