sanjay, and they say that they have surgeons here, waiting. and so, i was, actually, kind of curious. what type of -- of -- of injuries would they be expecting to see? >> yeah. >> but there -- there's surgeons here, waiting, just in case they can find somebody alive. >> these are some of the most complicated sort of search-and-rescue sort of missions. i've seen this in haiti. and i keep sort of an eye on the clock. we are about 28 1/2 hours, now, since the building collapsed and that's something that medical professionals are constantly thinking about, as well. if there are people who are trapped, what sort of -- what's their medical condition? are they -- are they crushed? do they have crush injuries? have they been in these pockets or voids that we've been talking about? they don't know. i mean, these are all sorts of considerations. so it's one of these ideas that you want to have as many resources onsite, as possible. even, possibly, placing ivs in people, while they're still -- you know, still being extricated, if needed.
