This is CNN 10 and I'm Carla Zeus.

It's great to have you watching this Wednesday.

It's been a year and a day since a passenger jet crashed shortly after takeoff in the island nation of Indonesia.

The flight was operated by Lion Air, a low cost airline, and the plane was built by Boeing, an American company.

That's part of the reason why Boeing CEO Dennis Muilenburg appeared before the U.

S Congress on Tuesday on the anniversary of the Lion Air crash.

And it wasn't the only one linked to Boeing's 7 37 max plane.

In March of this year, an Ethiopian Airlines flight crashed shortly after takeoff in Ethiopia.

It was the same model aircraft we can and must do better.

We've been challenged and changed by these accidents.

We've made mistakes and we got something's wrong.

We're improving and we're learning, and we're continuing to learn.

Both crashes killed everyone on board 346 people in all, and both crashes have been linked to a flawed computer system that repeatedly pushed the plane's nose is down despite the pilot's efforts to correct it after the Lion Air crash last year.

Some pilots said they didn't know the faulty computer system existed on the plane, and Boeing had apparently gotten permission from US regulators to remove information about the system from the 7 37 max manual.

That led some lawmakers to question the relationship between Boeing and the Federal Aviation Administration, which oversees Ares transportation in the United States.

7 37 max has been grounded around the world.

It's not allowed to fly.

Boeing says it's taken steps to fix the model that it hopes it will be allowed to fly again before the end of the year and that the crashes have taken a toll on its business.

Investigators say they identified nine areas of flaws and mistakes that combined contributed to the disaster of Lion Air Flight 6 10 which resulted in the deaths of 189 people off the coast of Indonesia, and that if any one of these factors had not taken place that perhaps this disaster could have been averted.

The blame, they say, lies with everything from the manufacturer of the 737 max eight plane that is bowing with a design flaw and certification flaws in an autopilot feature with the Florida based manufacturer of one of the sensors on the plane that was malfunctioning.

And then with the low budget Indonesian airline itself, the crew on board the final flight that they failed to communicate among each other about the malfunctions and in the final 11 minutes of the plane as it flew when the captain was wrestling with this autopilot feature that was sending the plane into a dive and he was forced to manually override it dozens of times when he handed off control of the plane to his first officer that that officer was not properly informed and quickly lost control of the aircraft and it went into its final, fatal dive.

The head of the investigation spoke to CNN and described this as a new kind of air disaster.

The U.

S Federal Aviation Administration has responded to the investigation, saying Quote, We welcome the recommendations from this report, and we'll carefully consider these and all other recommendations as we continue our review of the proposed changes to the Boeing 737 Max.

Now this new classifications of Boeing aircraft has been completely grounded because five months after the Lion Air disaster, an Ethiopian Airlines flight crashed as well, involving a Boeing 737 max and also this same flawed autopilot feature.

Boeing has come out with a statement saying that it has corrected the autopilot feature, that it has created new fail safes to prevent it from going automatically into effect if it gets faulty information related to the airplane's computer, and that it has improved training manuals to ensure that pilots will know what to do in the future if this autopilot feature kicks in.

Boeing says it has faced losses of up to $5 billion in relation to these two air disasters, and it will beak paying compensation of some $100 million to the families of the many victims.

Ivan Watson, CNN, Hong Kong Second Trivia.

What do Golden Eagles, polar bears, great white sharks and killer whales have in common?

Are they all mammals, endangered species, apex predators or Omnivores?

All of these animals are apex predators, meaning there at the top of the food chain.

And though great whites are considered a vulnerable but not endangered species, they appear to be vanishing from the area around a popular surfing beach in South Africa, and in this case, that's not a good thing.

There's a lot of mystery surrounding great whites.

They're the world's largest predatory fish, but scientists don't know how many of them exist.

They're known to migrate long distances, but scientists don't know exactly where they go.

Researchers are concerned, though, by what they're not seeing near Cape Town back.

But we've come to dive with an apex predator.

Still, Island is probably the world's most famous location for seeing great white sharks, and we see plenty of shocks.

Incredible ride after checked us are all right there, right there, right there.

But no great whites.

The shocks of scavenges not the iconic hunter that made this bay famous.

After millions of years in 2019 the great whites of Cape Town had vanished from me.

The loss of the great white sharks is losing part of my soul.

You know, this is an animal that shape my life.

It's given me some of the greatest hires off my life.

Chris Fellows, the photographer who put these shocks on the map, is forcing himself to speak in the past tense, the first time you saw this.

What was it like?

It was unbelievable.

I mean, everybody's fascinated by great white sharks but flying great white sharks to see this incredible super predator taking to the air, showing off its athletic progress.

That was fantastic.

This part seasoned Evan.

See, in the single sharks on the cliffs above, shark spotters used to take these sightings for granted.

This year, they've recorded zero great whites, not a single one.

What if they don't come back?

Yeah, we're just gonna have to wait.

Fishermen like Solomon Solomon say there are more seals now, two competing for their catch.

It seems the ecosystem is already feeling the effects.

The impact of losing an epic spread out for the marine environment is gonna be huge.

Biologist Sarah Andreotti says the zero sightings is alarming, but not surprising.

She predicted the collapse years ago in 2012.

By studying genetics, she found that the population was smaller and more vulnerable than anyone imagined.

What were your reaction to the population of great white?

Mostly about also a shock.

We were expecting to find 1000 or more individuals around here.

Overfishing, shark poaching and the week gene pool have all contributed.

People don't like to listen to sad story, and it is difficult to realize that humans could have have such a nim packed on such a pre historical, iconic predators.

Unless we really step up to conserve what we have left, South Africa's once bountiful shores are becoming more and more empty by the day.

If there's any hope for the great whites to return, he says, the focus should now be on what needs to be done.

Not about what once.

Waas David McKenzie, CNN False BAY, South Africa A friend of mine from college had this theory that the world was turning toe lint, starting with what's in our dryers.

I'm not saying this is proof, but it was collected from Dreyer's across the country to form a £690 ball of lint.

Why great question.

A dryer repair company wanted to set a new world record and to raise awareness about the importance of cleaning lint from our dryers because it's flammable as setting it on fire clearly showed, you could say it's parked up like flint.

A fire from a fiber flashing Clinton Flint.

What started as threads unraveled into shreds.

What started as a yarn was weak.

Quick to burn.

Does it seem off kilter to take a dryer filter and then clean it?

Just agreement for a demonstration?

It's a strange conflagration that lights conversation and concludes today's plays on CNN.
