know, 15 square miles, say. but when you think about it this way, it's like looking for, when you talk about a black box, imagine looking for, let's say a laptop computer, in manhattan in the dark, and it might be under a couple of meters of silt. so, it's a huge operation that they're just starting now. it should be down any time now. we haven't been told that it's been dropped into the water yet, but we were told it would happen today. it's what, 4:00 in the afternoon here now. one other headline out of that, christine was that in the next two or three days, angus houston said they're going to pretty much give up on the surface and air efforts to look for debris. they've been looking, of course, for weeks now, a few hundred miles west of where they're looking for the aircraft itself, haven't found anything, and they're probably going to wind that down in the next couple of days. you mentioned the oil slick. it could be something. it might not be. they've taken 2 liters of this oil from a slick near the search area. it's being brought back here to perth, will take a couple days to analyze that as well.
