Josh, sometimes rescuers need to blast rocks that have come down on a subject, to get them out. It's only one other tool that's involved in a rescue. Of course, if you're just thinking of big bombs...and Hollywood, then that's something to be scary of.
I remember in Merry 'Ole England, a number of years ago, when Keith Britain--no pun intended--put a micro blast against a rock that was holding a stuck caver inside a pothole, to free him from being wedged in tightly, similar to what could have been done at Nutty Putty Cave. Ah, well! That's over with!
