Transcript for Missing Malaysia Flight 370: #ASKWORLDNEWS Questions Pouring In
you to send in your questions about this mystery flight. You did. We got hundreds of them while "World news" was still on the air. I want to bring in our aviation expert John Nantz. Why isn't there a gps is the satellite low Kay or the on the box? He's exactly right. The problem is, if this thing is under 15,000 or 16,000 water, you can't get a radio signal out. I agree, if we can find an engineering solution that would be excellent. The next question has to deal with the cockpit and the pilots them, Cody asking, is there a legitimate reason to turn off the trackers? Well, we don't expect our pilots to be hiding and turning off the equipment for that purpose, so the system is not engineered that way, we have a legitimate need to turn those things off, if they're in the air and they malfunction, the same thing on the ground, too many airplanes on the ground squawking those systems could be a problem. Will that change thinking here? It could. Every one of those flights get to their destination. We have never had this happen before. I want to bring in David Kerley. This came up repeatedly, a viewer asking, why aren't they using submarines to help in the search? The U.S. Doesn't talk about what the submarines are doing or what they can do. The reason is, they work at 20,000 feet down, but they only radiate a signal about a mile, you have to be on top of it to actually hear it. So the sub may not be the best tool to do that with. To hear it, you're talking about the pinging, we know there are about two weeks later, this is what the sonar equipment would hear, this is what the pinging would hear like with those phones. John, you know that sound well. Gena asks -- how long after the original 30 days does the data remain viable? It will be there for many years. Because it goes on to a computer chip, as long as that chip is not compromised the data is there. Gentlemen, we thank you both. Remember to tweet us. We'll do this again tomorrow night, right here.
