I'm Carla Zeus and this edition of CNN 10 begins with news of a tornado and an avalanche first in the eastern part of the U.

S.

State of Alabama, rescue crews are searching through the wreckage left by an E F four tornado, according to one of the people.

Helping out the homes in its path didn't stand a chance.

We told you yesterday that a string of twisters killed 23 people in Lee County, Alabama, when this show was produced, officials said.

Several Maura's many as eight.

We're still missing.

There wasn't an official count of how many were injured, but nearby hospitals said more than 70 people have been treated there with injuries ranging from minor to serious.

One woman, who wasn't in her home when it was destroyed, described how her boyfriend barely survived.

Seeing the porch lab front porch is like a patio pacing that fly up, and he said he had just enough time to dive to the couch, which the couch is about a foot away from the screen door, and he just held onto the couch for your life.

Alabama's governor extended a state of emergency there.

It was originally issued last month because of tornadoes and severe weather, and one was also declared in three nearby Georgia counties.

That state's governor says more than 20 homes and a couple businesses were completely destroyed, and dozens more houses were damaged in some way by the storm.

A sheriff in eastern Alabama said it looked like someone had taken a blade and just scraped the ground.

What kind of disaster would have this kind of power?

It was just a violent rotating column of air coming out of the bottom of a thunderstorm, but it takes a lot to get that violently rotating column to come out.

All you need for a tornado really deformed, though, are thunderstorms and a jet stream that jet streams aloft.

It makes the energy.

If you have moisture at the surface, dry air, cold air, pushing that moisture up, you can get a 20 don't form in any state.

Those days were all the ingredients combined.

You get the humidity, you get the dry air, you get the jet stream, you get upper energy in the jet stream.

You get winds turning as you go aloft.

The higher you go, the winds actually changed direction that can cause storms.

Those things all cost warms to exist and get big Those of the ingredients that cause a big tornado date.

So now the E F scale enhanced Fujita scale starts at zero, goes only to five, and anything above 200 miles per hour is considered an e f five tornado.

If you have zero, you're gonna lose shingles a one.

You may lose a couple of boards on the roof to you lose all the windows and maybe even a wall.

Ah, three e f three.

You will lose a couple of walls on the outside, but there will still be a part of the home standing, and therefore, most of the home is gone, but you'll still see the refrigerator.

You'll still see a closet, and you'll still see the bathroom.

E F.

Five.

You cannot find the house.

It's completely we don't know how big that Fujita scale will be.

How big that tornado will be literally until after we look at the damage way have this almost his triangulation that no other country in the world know the region in the world has.

We have the Rocky Mountains to our west.

We have the Gulf of Mexico in our south.

We have Canada and very cold air masses coming down from the north.

All of those things combined make tornado out.

Typically, the planes Texas, Oklahoma, Kansas, Nebraska all the way to Chicago, as far south as the Southeast, including Georgia and Alabama.

That's basically the new or the bigger tornado Alley.

The greatest threat of a tornado is being hit by something that the tornado is moving if you're outside or for not protected inside.

If you'd hit by 100 40 mile per hour two by four, you're going to be killed.

So you need to be inside on the lowest level, somewhere in the middle of the home, away from Windows.

When you hear the word warning and you hear your county, that's when you need to take cover.

When you hear the word watch, that means something might happen.

Today.

Let's have a plan.

When you hear the word warning, it's too late to make a plan.

You need to already have a plan.

Warnings.

Long word.

It's the bed.

A little more than 24 hours after launching from Florida's Kennedy Space Center, a capsule made by Space X successfully docked with the International Space Station.

Here's why this is significant.

This was a test.

The company Space X was working to prove that its new capsule, the crew dragon capsule with capable of burying astronauts safely from Earth to the I S s.

No one was actually aboard the Crew dragon when it launched on Lee after it docked with the I S s.

Did the people who were already aboard the space station go inside the crew dragon?

Since NASA retired its space shuttle program in 2011 the U.

S has paid for astronauts to hitch a ride on Russia's Soyuz spacecraft to get to the I S s Space X could get them there on American vehicles.

Once again, Space X is considered a private company, while NASA is an agency of the federal government, those Space X has received billions of dollars in funding from NASA.

Assuming the rest of its current mission goes well, Space X plans to use its crew dragon capsule to ferry two astronauts to the I S s.

This July.

Which of these US bridges was completed in 1937 Golden Gate Bridge, Brooklyn Bridge, Mackinaw Bridge of Seven Mile Bridge.

Neither the oldest nor the youngest on this list, but the Golden Gate Bridge is the only one that was finished in 1937.

At that time, it was the world's tallest and longest suspension bridge, and two of the elements that challenged its construction storms and fog continue to test the Golden Gate Bridge today.

Part of it had to be closed to traffic recently after a lingering thunderstorm damaged It's north bound lanes and protecting it from corrosion and rust is a never ending battle.

The Golden Gate Bridge gets its name because it spans what's called the Golden Gate straight.

This is a three mile long and one mile wide body of water that connects the Pacific Ocean to the San Francisco Bay.

Before the Golden Gate Bridge, there was a bustling ferry system that ran people and commerce between San Francisco and the Redwood Empire to the north.

It's actually unknown how many people worked on the Golden Gate Bridge at the time of construction because records were scarce from that time.

Today we have close to 200 employees who work to maintain to paint toe.

Well, Thio, make sure that the bridge is in good on safe operating conditions.

So we're right now getting sand blasting on the outer part of the bridge, which is up underneath right now with the walkway, is where the pedestrians ride after 3 30 So the cars are probably just about 15 feet out.

You can't feel it, but the bridges by moving, you know, like this.

We're standing in a containment like this.

A rough estimate.

16 people sand blasting for a month and 1/2 are.

Painters will go out to the most critical structural areas of the bridge, where the fog and the salt and the wind has corroded the paint.

The salt eats this bridge up the fog.

Eat this bridge up.

If we don't continue to paint it, it's just gonna rot away.

Theo having the right tires can make a car fly, and in this case, we mean that literally.

This is a tire companies concept.

It's not riel yet.

It would have tires pull double duty as propellers that could reposition upward to take a car up up.

In a way, it's being pitched as part of an autonomous car of the future.

No idea how much something like this, plus the flying car would cost.

But if you're asking, why do you need four of them?

It's because half that many would be too tired to fly.

I thought that was a really good pun.

You could almost hear the rim shot afterward.

It's fun to take ideas like that for a spin.

Not every pun has been spoken for, and we're always driven to ride out some.

Or even if that means sounding a little lug nut e at the end of the road.
