david maddingly, thanks to you.t to bring in richard quest and miles o'brien into this conversation. richard, this is stunning when you think about this, in this day and age, right, you haven't had wars like this in a long time. the technology intended to be youed for that purpose is out there and it's so sophisticated. and it's amazing. >> and they keep having to refine it and adapt it. and you need look no farther than that inmarsat satellite. many of those satellite systems were similarly designed for warfare. originally. and now being adapted again and again and again to take advantage of these new situations. because they really are -- the clock is ticking on those pingers. we know there are days left, if that. therefore, what i'm guessing and assessing is that angus houston is now throwing everything he's got, sonobuoys, the echoes going up there, every bit of craft he can possibly get is heading to the area. >> and of course he is the man in charge of the search. >> yes. >> miles, it is pretty stunning. with
