Waching daily Sep 2 2017

Hi. I`m Carl Azuz. It`s a privilege to welcome you to CNN STUDENT NEWS, ten minutes of commercial

free current events. First up this Wednesday, April Second, General Motors has seen better

days, the maker of Buick, Cadillac, Chevrolet and GMC has recalled more than 2.5 million

vehicles worldwide. The reason - a problematic ignition switch that can slip out of place

while someone`s driving. Disabling the engine, the airbags, power steering and power breaks.

GM`s new CEO Mary Barra was on Capitol Hill yesterday. She was there to apologize and

to answer investigators` questions. GM says the ignition switch problem caused 13 deaths

and car accidents. And because ten years passed between the time when the problem was first

discovered and when GM ordered the recall this February, lawmakers are trying to find

out why the company waited so long.

Backup cameras. If you`ve been inside a newer truck or SUV, you might have seen one. It

gives you a view of what`s behind the vehicle. That appears on the screen in the dashboard

or a rearview mirror. At the moment, backup cameras are in option on many cars. The U.S.

government is making them the law. All new cars, SUVs, trucks and vans will have to have

one by 2018. The government estimates this will save between 60 and 70 lives every year,

and they`ll increase visibility, especially in larger vehicles. Some families who`ve lost

loved ones in backover accidents, say the law is long overdue. But it will add to the

cost of cars. The government estimates a complete system will start at $132. And some critics

say smaller vehicles like roasters or smartcars simply don`t need them.

What you are about to see almost looks like a scene from a war movie or a on older version

of "Call of Duty" but this is real. This is recent. This is from Syria. Someone mounted

the camera on a tank to get this. And notice, not just the firing, but the areas around

the tank. Shot up, shell, burned out buildings where people used to live, shop and work.

These are scenes from Syria`s civil war, which started three years ago. It`s between the

government forces of Syrian President Bashar al-Assad and various rebel groups who want

that government out.

Terrorists have also joined in the fighting. One observation group says at least 150,000

people have been killed in the civil war. As many as a third of the victims are reportedly

civilians.

A United Nations` peace mediator said last week, that talks between the Syrian government

and the rebels are unlikely to continue any time soon. So the war will likely rage on.

There`s not much new information to give you about a missing Malaysia Airlines passenger

plane. Nothing has been recovered after 26 days. The batteries on the plane`s locator

beacon are probably running out, but you`ve got to be close to be close to the wreckage

to hear the beacon. Officials` orient. One reason the search has been so difficult is

because the ocean is so vast. We know more about the surface of Mars than what`s under

the surface of our oceans.

You can`t take a picture from a satellite of the ocean floor and get the symmetry, get

the up and down, get the canyons. You just can`t see through the ocean far enough. So,

how do we get that data? We have a pinger on the ship and the ship moves along. While

the pinger just like a fish finder, finds the bottom, depending on how far away the

bottom is, that`s about a mile or so width. It can be farther. If it`s a 12,000 feet the

beam goes out farther. So, its` a wider footprint. But the ship could really only go about five

miles per hour or so to get a really decent ping if you`re trying to map the bottom of

the ocean. And try to go faster, but here`s what happens: when you ping, and then you

wait for it to come back up, if you are going too fast, the ship is here, and ping will

get to the transducer on the bottom of the boat. So, you can`t go too fast.

So, five miles per hour, that`s the assumption, one mile width, that`s the assumption. So,

that`s five square miles per hour of the ocean.

There`s 130 million square miles of the ocean bottom. I did the math, I divided it all up.

If you never stop for fuel and you never stop for new sailors, it will take you 2955 years

to map the ocean with one ship. Here`s the deal: we`d love to have a pattern here in

the past that looks something like what (INAUDIBLE) back and forth, and back and forth, and back

and forth, there`ll be a couple of miles, you need to get a really great sense. We don`t

have that. What we really have are these lines where ship went that way. And then a ship

went that way. But there`s an awful lot of blue in between all of those spots. And do

the same thing for the U.S., it`s a lot better because of NoVa, all of this has been essentially

mapped, we get some blue skies, blue areas out here, far enough away or far enough out

here in the Pacific, but on the way back and forth to Hawaii, down here pretty good, even

off the coast of Mexico pretty good. It`s because of the remoteness of that ocean that

we simply don`t know what it looks like.

Here`s what a stereographic picture looks like of the Moon. Two pictures side by side,

we know how deep this crater is, we even know the size of it back and forth. And we also

know that there`s a crater inside the crater.

Here`s what Mars looks like. It`s pretty incredible as well. All of the craters that we have here

on Mars, all because of 3D mapping. You get two eyes or you get two cameras, you take

a pictures of the same thing. It can`t see three dimensions. We can`t see through the

water to do the same thing on the ocean floor.

In 2013, 94 million passengers travel through Hartsville Jackson international airport in

Atlanta, making it once again, the world`s busiest airport. There are almost nine miles

of runway, 2600 takeoffs and landings in one day. 250,000 passengers a day. It`s a few

miles from where we produce this show, and CNN wanted to find out what it`s like for

an air traffic controller with so much up in the air.

62 heavy contact (INAUDIBLE).

When you push back off the gate, you`re going to be talking to an air traffic controller

from the minute you start taxing to the runway till you get to your final destination.

We have five parallel runways, and I was working departures for runway 2a.

This is one 11 contact departure.

I`m talking directly to the pilot in the cockpit, and I`m issuing lineup and weigh procedures,

which means you`ll line up on the runway and issuing takeoff clearances.

32 contact departure.

We run 2700 airplanes a day. Volume breeds complexity here in Atlanta. There`s so many

aircraft coin for a tax instructions, so many aircrafts returning from the landing runways

trying to get to the gates.

You`ve got to stay alert. And you`ve got to be focused at all times. Because of the volume

that we have here, we run probably about five or six emergencies a shift. There`s a cardiac

arrest patient, a woman going to labor on an aircraft. People having strokes on aircrafts.

Smoke in the cockpit. That happens here every shift every single day.

But when is aircraft coming to the airspace, we get him into the airport as quickly as

possible. You probably wouldn`t even notice it. It`s just another day at work and the

guys - they are professionals. We just keep moving.

I always liked the aviation since being a kid. We used to have a little matchbox airport

that you could fall down and (INAUDIBLE), airplanes and stuff like that. It was one

of my favorite things I can play with. But I get to play with them for real.

But don`t misconstrue what I`m saying. What we do here is extremely important. The sheer

volume of what we do every day and doing it without any - without a hiccup. That - job

has faction enough.

It`s Worldwide Wednesday - get ready to go globetrotting. We are happy to be part of

your day at Esquela, Americana, glad to see students in San Salvador, El Salvador are

watching.

Up north, in Ontario, Canada, hello to our viewers at (INAUDIBLE) Boulevard Public School.

I hope you are enjoying this show there. And in Konya, Turkey, we are online at Mevlana

University. Thank you for taking ten minutes for CNN STUDENT NEWS.

Time for "The Shoutout." Whose home field is located at 4 Yawkey Way: let`s play ball.

Is it the Seattle Mariners, Houston Astros, New York Yankees, or Boston Red Sox? You`ve

got three seconds, go.

4 Yawkey Way is the address of Fenway Park, and that`s the home of the Boston Red Sox.

That`s your answer and that`s your shoutout.

But the bow (ph) Sox. We (INAUDIBLE) been yesterday. They were in the Capital and not

for a game with the Nationals. They were enjoying an American tradition when a championship

team gets a trip to the White House. The Sox won the World Series last year, so they visited

1600 Pennsylvania Avenue yesterday, presented the president with an honorary jersey and

posed for a picture, though David Ortiz took the chance to snap a selfie. The president

didn`t need a pitch. He played right along. It seemed like everyone was having a ball

- no one looked like he was in the foul mood. No one seemed to have a bad time. Of course,

maybe we are being empirical, but the snap selfie crossed no baselines, there were mounts

of smiles and everyone got home safe. I`m Carl Azuz and CNN STUDENT NEWS is out.
