It's always good to see you.

A growing number of countries around the world are grounding a popular type of passenger plane, and that's the first story were explained.

On Sunday, an Ethiopian Airlines flight crashed shortly after takeoff in the capital of Ethiopia.

All 157 people aboard were killed.

It happened less than six months after an incident on October 29th when a Lion Air flight crashed shortly after takeoff in the capital of Indonesia.

All 189 people aboard that flight were killed.

The one thing these two flights have in common is that they were aboard new models of the same airplane of Boeing 7 37 max.

Eight.

It was introduced two years ago.

It's a very technologically advanced jet, and it might be that technology that's causing its problems.

Boeing Bills 737 Max was the fastest selling airplane in the company's history.

The high tech single I'll Jet Maur than 5000 on order for 100 airlines worldwide.

Many of them are in China.

On India, 737 has a long history since the first twin jet baby.

Boeing was introduced in 1967.

It's grown into the best selling line of commercial jets in history.

Max.

Eight Variant launched in 2017 seats up to 200 passengers.

It was designed to offer airlines greater range better fuel efficiency from the models that came before.

Like any new Siri's, Boeing introduced a brand new technology and features into the 737 Siri's, including automatic safety system.

This particular aircraft has a new something new as faras.

How the autopilot responds when the angle of attack.

When the aircraft nose goes up too high, it pushes that nose down even when the auto pilots off.

And a lot of pilots aren't used to that.

In the case of Liner Indonesia and investigators say, pilots repeatedly Fort Toe override that system before the fatal crash of the plane back in October.

Preliminary crash report said faulty sensors that the automated system toe push the nose of the plane down again and again.

It's not clear why the pilots did not follow recognized procedure.

Turn the system off Now This crash, the second in a brand new model plane shortly after takeoff.

It's provoking more questions about the plane's design on what Boeing has told.

The airlines, CEO of Ethiopian Airlines, says the pilot had flight control problems shortly before the plane crashed.

But both accidents involving this Boeing model or under investigation, and there's no evidence at this point that the same problem caused them.

Still, countries from Australia to China to the European Union and India have grounded the 7 37 max eight airplanes, making it illegal for them to fly in or over these nations, according to the Reuters news organization.

Boeing says it's been developing a software update for the plane.

That's quote designed to make an already safe aircraft even safer.

The U.

S Federal Aviation Administration also said earlier this week that the aircraft is safe, though it has ordered Boeing to make some design changes to it.

Some U.

S senators are now saying the FAA should temporarily grounded until it's proven airworthy.

The U.

S and Canada are the only two countries where substantial numbers of these planes are still flying.

The United States government is trying to keep American wireless companies and countries around the world from buying telecommunications equipment made by a Chinese company named away.

This is the world's largest telecom manufacturer.

It's taken such a lead in developing five G wireless technology that many carriers can't replace.

It five g is said to be many times faster and more reliable than four.

G.

China and Walk Away have denied doing anything wrong.

But the U.

S says Wall Way has connections to Chinese government intelligence and that Wall Ways equipment could allow China to potentially spy on people who use it.

It's not just civilian security the U.

S is concerned about.

Hidden beneath this vast snowy prairie land in central Montana are more than 100 nuclear armed intercontinental ballistic missiles ready for launch.

It's desolate terrain but vital to American national security, which experts worry could face a threat from China.

This fenced in area is a missile silo controlled by Malmstrom Air Force Base right next to it a cell tower belonging to a company called Triangle Communication System.

It's an American company, but its network uses radio transmitters and receivers made by the Chinese company Wall Way, a telecom giant that has been called a national security risk by U.

S.

Intelligence officials were deeply concerned about the risk allowing any company or entity that is beholden to foreign governments that don't share our values to gain positions of power inside our telecommunications networks.

Given the power of the Chinese government over Chinese companies, experts say the Wall Way technology could be weaponized by Beijing if they asked why Away, turn off the phones.

Tell us what people are doing.

Scramble the data going over it.

Blocked calls, make random phone calls.

There's nothing we could stop that.

Thes bases use encrypted communications, but valuable intelligence could be gathered on the people working with the I, C, B M, and the area could also be targeted with network attacks.

There's no evidence that anything like this has happened, but CNN has identified dozens of cell phone towers equipped with Wall way technology, some dispersed among the Malmstrom nuclear missile fields.

I C B M.

We're supposed to be pretty hard.

That might not be easy to do, but that doesn't mean our opponents won't try and figure out if they can do it.

Areas like this are so remote that often the only cell phone service comes from small networks, unlike major carriers like Verizon and AT and T smaller companies depend on government subsidies, and many buy cheaper equipment made by Chinese companies like Wal Way.

While the company is barred from U.

S government contracts and federal employees can't use their devices, rural carriers have no such restrictions.

The companies that own these towers are part of the rural Wireless Association, who say 1/4 of their members by Wall Way because it's far cheaper and say it would cost upto $1 billion to replace.

The Pentagon would not say what kind of relationship, if any, it has with these carriers.

But acting Defense Secretary Patrick Shanahan told CNN in a statement, They are working closely with our industrial and research partners to develop comprehensive and innovative solutions for both the department and commercial industries.

10 seconds Trivia.

Which of these American universities is the oldest?

Wake Forest?

Georgetown.

Stanford University of Southern California, the oldest university here, and the only one on this list that was found in the 17 hundreds is Georgetown.

50 people across the United States have been formally charged with cheating.

To get students in the highly respected college is the FBI's criminal investigation was called Operation Varsity Blues.

It covers crimes allegedly committed between 2011 and 2019 and it led to the arrests of athletic coaches, s A T and a CT administrators and dozens of parents.

What they're accused of doing is helping students cheat on college entrance exams like the S A T and paying some sports coaches to say certain students should be admitted to their colleges because the students were good athletes even when they weren't.

In some cases, this involved creating fake athletic profiles for students to make them look like good athletes.

Prosecutors say the cheating was carried out mostly without the student's knowledge, according to ABC News, and that it was done to get them into schools like Yale, Georgetown, Stanford and the University of Southern California, among others.

The interim president of USC called it immensely disappointing that school employees would allegedly abuse their positions in this way.

A U.

S attorney involved in the investigation said.

For every student admitted through fraud, an honest, genuinely talented student was rejected.

U.

S officials say this was the largest college cheating scam the federal government has ever prosecuted.

When you see this winterize car for the first time, don't be fooled It's no Mustang.
