photo interpreter, 92 years old, still has a cia clearance. i said what do you make of the images released by the australian government? he said what's important is there are lots of images from this same area nld it will be important for photo interpreters to superimpose images of a 777 on these parts, cut and paste, basically, superimpose them and determine whether or not this is a plane. i assume that applies to this recent chinese image. is that what photo interpreters are doing right now in our government or other governments? >> they're trying to look at an expansion of ocean that is hard for us to contemplate. the first thing is how do you scan millions of miles of ocean in a timely period? what we've got now is not only scanning that piece of territory, what we've got is saying if you don't find that in your photo interpretation within 24 hours with swirling currents, with the fact it might have sunk, the likelihood a ship, helicopter, plane is going to find that three days, four days, five days later to my mind is minimal but we're chasing it
