CARL AZUZ: Welcome to
our viewers worldwide.

I'm Carl Azuz.
And this edition of "CNN
10" begins with news

of a tornado and an avalanche.
First, in the eastern part
of the US state of Alabama,

rescue crews are searching
through the wreckage

left by an EF4 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 more-- as many
as eight-- were still missing.

There wasn't an official count
of how many were injured.

But nearby hospitals
said more than 70 people

had 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.

- He seen the porch fly up--
the front porch.
It was like a patio.
He seen that fly up.
And he said he had just enough
time to dive to the couch,

the couch was about a foot
away from the screen door.

And he just held onto
the couch for dear life.

CARL AZUZ: Alabama's governor
extended a state of emergency

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?

CHAD MYERS: Technically
a tornado is 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, to form,

though, are thunderstorms
and a jet stream.

That jet stream's aloft.
It makes the energy.
If you have moisture at
the surface-- dry air, cold

air pushing that moisture up--
you can get a tornado
to form in any state.

Those days where 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
change direction.

That can cause storms.
Those things all cost
storms to exist and get big.

Those are the ingredients
that cause a big tornado day.

So now the EF scale--
Enhanced Fujita scale-- starts
at 0 and goes only to 5.

And anything above
200 miles per hour

is considered an EF5 tornado.
If you have a 0, you're
going to lose shingles.

A 1, you may lose a couple
of boards on the roof.

A 2, you'll lose all the
windows and maybe even a wall.

A 3, EF3, you will lose a
couple of walls on the outside,

but there will still be a
part of the home standing.

And at 4, 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.

And EF5, you cannot
find a house.

It's completely gone.
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.
We have this-- almost
this triangulation

that no other country in
the world, no other 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 Alley.

Typically the Plains,
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 if
you're not protected inside,

if you get hit by a 140
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 the plan.

"Warning's" the long word.
It's the bad one.
CARL AZUZ: A little
more than 24 hours

after launching from Florida's
Kennedy Space Center,

a capsule made by SpaceX
successfully docked

with the International
Space Station.

Here's why this is significant.
This was a test.
The company SpaceX was working
to prove that its new capsule,

the Crew Dragon capsule, was
capable of ferrying astronauts

safely from Earth to the ISS.
No one was actually aboard the
Crew Dragon when it launched.

Only after it docked with
the ISIS 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 US has paid for
astronauts to hitch

a ride on Russia's Soyuz
spacecraft to get to the ISS.

SpaceX could get them there on
American vehicles once again.

SpaceX is considered
a private company,

while NASA is an agency
of the federal government,

though SpaceX has received
billions of dollars in funding

from NASA.
Assuming the rest of its
current mission goes well,

SpaceX plans to
use its Crew Dragon

capsule to ferry two astronauts
to the ISS this July.

10-second trivia-- which
of these US bridges

was completed in 1937?
Golden Gate Bridge, Brooklyn
Bridge, Mackinac Bridge,

or Seven Mile Bridge?
It's 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 its northbound 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 Strait.
This is a 3-mile-long
and 1-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, to weld, to make
sure that the bridge is

in good and safe
operating condition.

right now getting

sandblasting on the
outer part of the bridge,

which is up underneath.
we're where 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
bridge is probably moving

like this as we're standing.
JARROD BAUER: In a containment
like this, a rough estimate--

16 people sandblasting
for a month and a half.

Our painters will go out 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 eats this bridge up.
If we don't continue
to paint it,

it's just going to rot away.
CARL AZUZ: Having the right
tires can make a car fly.

And in this case, we
mean that literally.

This is a tire
company's concept.

It's not real-- yet.
It would have tires
pull double duty

as propellers that
could reposition upward

to take a car up, up, and away.
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
"wheelie" 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 "spoke-en" for.

And we're always driven
to ride out some more,

even if that means
sounding a little "lug

nutty" at the end of the road.
I'm Carl Azuz, and
that's "CNN 10."
