randy kaye, cnn, new york. >> and john joins us now. he is the first ever certified airframe and power plant mechanic to be on the national transportation safety board. few know more about how planes are put together and can come apart. how likely is it that this was a catastrophic mechanical failure rather than something more few neighb -- nefarious. >> it is unlikely it is a fuel tank explosion because of the effort to make sure that doesn't happen again. there was a tremendous amount of work and resources that went into making sure that we won't revisit that event again. there are other things that can happen to an airplane to cause them to come apart, some of them pretty easy. but the scenario that we have today doesn't fit any of the easy theories. something happened up there. it could have been a computer failure or inappropriate actions on the part of the pilots that stalled the airplane or a device on the airplane. it's not likely an engine that failed catastrophically and broke apart. it was something a little bit different tha

so yeah, that's what's changed. >>> check in with randi kaye who has a news bulletin. >> anderson ingo there is now a $20,000 reward in a brutal killing of a 9-year-old. tyson lee was shauot down in an alley on the way to his grandmother's house. >>> in oregon and washington state, officials there are now 37 cases of e. coli likely linked to chipotle res raunts. chipotle has closed a number of locations as a precaution. >>> a violent confrontation caught on dash cam video. a taco bell executive has been fired after attacking an uber driver because the executive was too drunk to give him directions. the driver used pepper spray to fight him off. the passenger has been charged with assault. >> that's incredible. thanks very much. >>> breaking news just in. cnn cannot independently confirm this, however the state-owned news agency russiana 24 is reporting more information on the spread of the debris field. the network is reporting that the tail ended up five kilometers or about three miles away from the rest of the wreckage. the tail did not have any signs of burning from a fire. that a

randi kaye, cnn, new york. >> want to dig deeper on this with our terrorism analyst and paul chook --ank. paul, i mean, we've talked a lot about groups and saw it there trying to use sophisticated methods, the ink jet cartridge. they say that's a relatively easy thing to make. and a relatively crude device. >> a very conventional device, meat and potatoes. the crucial factor here may be that they recruited an insider at the airport. and if you can do that, that's the holy grail for terrorist groups. because then you can insinuate the bomb on to a passenger aircraft. there have to be considerable concern that there could be other insiders at other airports. they haven't apprehended the potential insider who may have got this bomb on to that jet. >> bob, i mean, again, a bomb with the barometric pressure switch, are they easy to make? it's a worrying thing for those of us that don't know much about explosives. >> anderson, it's very easy, this technology is old but it's reliable. it's worked on several attacks in the '70s. the bombs went off. you know, the detonators can be smuggled on.

however as "360's" randi kaye found out, they do have limitations. >> reporter: this is the sound of a pilot in trouble. >> swissair one-11, we have to land immediate. >> reporter: that was the pilot of swiss air flight 111 minutes before he crashed into the atlantic ocean in 1988. everyone on board was killed. when crash investigators found the plane's black boxes at the bottom of the ocean, they looked intact, so they were stunned to learn this. >> both the recorders stopped recording about six minutes before the aircraft actually hit the water. >> reporter: leaving investigators to wonder why they suddenly lost control of the plane. it was a fire they later found in the jet's entertainment system, but it took putting the plane back together, all 2 million pieces of it, back to figure that out. bottom line the so-called black boxes aren't perfect, even when they are found to be in good condition. they may not reveal the cause of the crash. on a plane they are tucked inside an insulated case surrounded by stainless steel designed to withstand temperatures as high as 2,000 degrees fa

i'm randi kaye in dannemora, new york. i'm standing just yards away from clinton correctional facility, where inmates richard matt and david sweat broke out of. it's the first escape from this facility since it opened in the late 1800s. that story was a story almost too twisted to believe, involving betrayal, manipulation, and sex. before the sun even began to rise over the small town of dannemora, new york, they were gone. an escape plan worthy of a screenplay carried out by two very dangerous men. >> on a scale of one to ten, they are a ten, dangerous wild animal. >> prisoners richard matt and david sweat had adjoining cells here at clinton correctional facility. the two were last seen friday night, june 5th, around 10:30 p.m. during what's called a standing count where both matt and sweat showed themselves standing inside their cells. but just hours later, a shocking discovery that would leave prison guards shaking their heads, law enforcement on high alert, and this small upstate new york community terrified. >> this w

randi kaye, cnn, new york. >> a lot to discuss.litical commentators, jeffrey lord and political day rector and me maria cardona. does it seem odd trump's appearance is where some activists are drawing the line. why is this hour and a half of "snl" suddenly the breaking point? >> well, i think part of it is, anderson, that being invited to do "snl" as you know is a huge platform. it is reserved for i think the highest form of celebrity for the highest form of people of the moment and so to the latino community, it seems like slap in the face for "snl" to give this platform of an hour and a half to somebody that's been so offensive to latinos in this country and very curious to see that five months ago, nbc put out a statement right after donald trump made those very offensive remarks saying that those remarks slashing ties with donald trump and saying those remarks did not comport or represent the values of the principals from nbc. what happened with those five months. they realize he's still a ratings juggernaut and at the top of t

when randy kaye was interviewing evangelicals in iowa, these are full dimensional people and you ask them for concerns and it was the economy. and they kept coming back to donald trump. so i do think that comes together for a lot of people. >> donald trump, i mean, it was telling because bush was trying to intervene to say you're wrong and trump was wrong. the russians aren't trying to knock out isis. they are going after the rebels who are anti-assad. so the theory was wrong. he said it with bluster and he said it with vigor but it's just not true. >> bush didn't really hit that point, really. >> that is a fundamental problem. >> all about jeb bush. >> jeb himself has admitted he's not good at this. he is not a good debater or performer or entertainer. what i think people saw is a guy who is not defeated or giving up. who worked hard as hell for the last ten days and he is going to keep fighting and trying and be focused and invigorated and go through with it. they saw a guy who is improving with each performance. i think that anybody who is a jeb bush supporter like me saw what the
