Systems of taircraft from underneath the airplane? unfathomable to me. >> unfathomable. try to put some fathom into it for me. >> this airplane was flying over the ocean. radar is only good for about 200 miles from shore. so you don't have to fly at low altitude to be undetected once out get beyond the range of radar. as we discovered on 9/11 in this country and certainly in places like malaysia and thailand, there are not fighter planes waiting to scramble to chase unidentified aircraft. it just doesn't work that way. the ocean is very large, very dark and very easy to disappear into. >> okay...

Altitudes and not be picked up by primary radar. that's not a surprise. it's been around for years. so that doesn't surprise me in the least. the range of the aircraft changes dramatically at those low altitudes, though, so you don't have as much range as you did before. but fact is that that aircraft, i've got credible evidence that aircraft was at those altitudes. i'm going to accept that. i'm going to call that an apple. look at that apple and that's what it is. i can't see it's anything else. >> talking apples, if i had an iphone, pretty certain if i dropped it in new york then i could pro...

Plane, the actual equipment that is used to speak to the ground and to identify the aircraft, et cetera, et cetera, went down. after it went down, a primary radar kept tracking this plane. this does not have the same level of sophistication, but it can actually track the plane itself. and it tracked the flight back in a big u-turn back across the country of malaysia on to the other side of the kcountry. the last known whereabouts of this aircraft before it disappeared, before that actual radar image disappeared from the screens, was more like a lump of rock than anything, roughly halfway betwe...

Working. we don't know why. it was then tracked on what's known as a primary radar. but the primary radar does not have the same level of sophisticati sophistication, cannot pick up what plane it is. but they continued to monitor this plane, which they consider -- they thought to be flight a-370. it did a u-turn. it flew back across malaysia, as i said, across into the straits of malacca. that was about -- for about one hour or so. and that radar image they were looking at disappeared around this very small island, pretty much in the middle of the straits of malacca, between malaysia and indon...

That plane down, they could have turned off the transponder and just taken that plane down. why would they fly an extra hour if their intention was to destroy the aircraft and kill everyone on board. >> i agree. i certainly agree. >> that's an important point to make. brian todd is with us, as well. brian, you have been doing some reporting on the search techniques that are under way right now. what are you learning? >> reporter: well, wolf, you know, we focus a lot today on the technology. as you have been reporting in the breaking news, at some point we now know the plane's transponder stop ...
