we also spoke with uzi ruben. uzi joined us on the phone from israel. started by asking about the technology behind israel's missile defense system, the iron dome and how it keeps israelis safe. >> there are missile defense system works like -- to make it -- look at it and shoot it. and kill it. it sounds simple when i say it. the implementation is difficult. it is like hitting a bullet with a bullet. the incoming missile is flying about twice the speed of sound. you have to find it. you have to find it in the sky and hit it. easy to say, difficult to be done. >> ari, let me ask you, uzi's missile defense system was a response to other failures in the past using new technology. what new technology are you using with red alert that was not possible in the past? >> basically, red alert when i created two years ago before i started working here, it is very basic technology and technology that any app developer could use on -- any day he wants to. we are not using anything so sophisticated here. as the numbers of people who are subscribing to our app, we se

uzi, i will start with you.d a lot about the technology and sophistication of the iron dome which helps prevent israelis from rocket attacks. can you explain how this works from the technological perspective? >> it works like an air defense system. you have radar or another sensor that sees the target. and calculates the trajectory of the rocket. it intercepts the missile. it shoots it and kills it. the principle is simple, but implementation is quite difficult because it is like hitting a bullet with a bullet. the incoming missile is flying about twice the speed of sound. you have to find it. you have to find it in the sky and hit it. easy to say, difficult to be done. >> uzi's missile-defense system was a response to other failures in the past using new technology. what new technology are you using with red alert that was not possible in the past? >> basically, red alert when i created two years ago before i started working here, it is very basic technology and technology that any developer could use on a dail

uzi, over like to ask you the last question.ch sophisticated missile defense and missile technology, could this technology at all be used to better target places in gaza where children are not playing for example? , mirrors willly happen -- errors will happen. [indiscernible] i want to point out an important fact. toas has sent its rockets installations. -- let meo way stressed this point. every rocket that comes out of gaza. that plays can be hit and destroyed. it, but thestopped cost of human life would be tremendous. so we do not do it. that is called human shielding. yourappreciate you sharing perspective. creator from jerusalem. thank you both. elon musk is not the only one working on high-speed to transport -- tube transport. we are talking to one person who can shoot you from new york to beijing in just two hours. ♪ >> welcome back. we turn back now to our wiring the world series where we are looking up is shaping the future of transportation. elon musk envisions as hyperloop transportation system as a way to get the citi

so in a sense lu,uzie's experiee is not something for us to read and absorb and cry over and occasionally smile over, it's also a challenge. i believe it's a challenge to each and every one of us to ask ourselves are we capable of such action? quiet, unheralded, unsung, under very difficult circumstances, susie, as you said a while back when people depended on mail and it was not always the most reliable thing in wartime. mail across oceans and continents. so the second thing for me about luzie is that when i got to know her, she was very deeply involved in our pioneering german programming. now, that may at first glance not have been the likeliest place for luzie to spend her life. after all, a few years before she had fled germany. she had spent years trying to get her family out of the clutches of the third reich. and yet here she was a couple of decades later in the forefront, devoting a great deal of her life to trying to build new bridges of understanding and cooperation between germany, the jewish people through the vehicle of ajc. and that, to me, as well as a very -- is a very po

an uzi was inside a locker yesterday at the walter d palmer leadership partners charter school in frankford. officials changing locker combinations found the gun. no students were in the school at the time. it is unclear how long the gun had been there. >>> well, ten people are homeless this morning, after two homes collapsed in the cobbs creek neighborhood of philadelphia. happened 60 he and spruce street, bolt a gist end properties, 6015 and 6017 came crumbling down, yesterday morning. no one was injured during this collapse. at least four other homes sustained damage. neighbors are very concerned about their homes. >> never in my life. even ten years in the military never seen it. >> i think they should take better look at all of these houses on the block just to make sure. >>> l & i inspectors went door-to-door last night checking basement walls. and foundations in every home in the 6,000 block of spruce street. preliminary reports suggest the party wall between 6015 and 6017 gave way for some reason yet determined. nicole? >> ukee, frustration over the philadelphia fire department's re

official, a border patrol agent for example, i'm a murderer, i have killed people with an uzi.8, there is nothing we can do about it? >> there is nothing that border patrol can do about it at this point because they are classified as minors. and so these gang members who are in these countries el salvador, honduras, guatemala understand that and they are coming through these processing centers and using these as hubs, actually using the phones inside those processing centers not only to communicate with gang members not only back in home countries about to communicate with people in the united states. if you look at the documents closely you will see that 15-year-olds, 16-year-olds, gang member minors were actually on their way to their parents who are living in the united states illegally. >> and, yet, somehow, we have decided, the obama in administration has decided there is nothing we can do to protect ourselves from these people. have any been deported that you know of? >> there are no reports of them being reported. border patrol's job is to process them through and then t

are we talking about bringing an uzi into the tabernacle. >> if you have a license to carry, i can say yes, you can do that. however, the tacker knackle's not going to let you do it, so it's a moot point. >> mr. henry, thank you for being with us this morning. >> we're going to change gears here. some country music stars helping people with developmental disabilities tap into their creative potential. as jonathan martin reports, they're helping researchers study a rare disorder. >> i love what you say about the colors. >> it looks like a typical song writing session working on a new tune. as you'll see and hear, this is something special. >> let's take ideas from everywhere. >> this music camp is for young adults with williams syndrome, affecting almost 30,000 people in the u.s. it causes cardiovascular, learning and developmental disability. those are the disorder have strong verbal schools and affinity for music. >> some are very talented and others interested in music and focus on their unique strength, which is music. >> they came here to record their song and that's where the magi
