Well, the tradition of celebrating America's independence with fireworks dates back, listen to this, to the first recorded organized Fourth of July celebration in 1777 in Philadelphia.

When it comes to celebrations and celebrating major milestones with fireworks, there is no question about it, Las Vegas sure knows how to do it right.

America 250 celebrations here in Southern Nevada kicked off in June with firework shows up and down the Las Vegas Strip and Downtown Las Vegas.

We got a firsthand look at how these impressive fireworks displays are set up on a Strip rooftop.

Check it out.

-When you see that first push of fireworks coming up, it's, it's, you always get the jitters.

-Before that initial burst fills the Las Vegas sky... ...Jonn Massirio, Lead Technician with Fireworks by Grucci, and Tex, Anna, and Oscar are hard at work on the rooftop of the Treasure Island... (Jonn Massirio) So you go to these right here.

-...putting the finishing touches on yet another impressive fireworks display.

-On rooftops here, we're allowed to do 75-millimeter shells, which definitely add to the effect.

You can imagine we're on the rooftop this high.

Now we're sending the shell another 280-300 feet here, right?

So those bursts are well above the Las Vegas Strip where everybody could see the full visual.

-A project of this magnitude takes months of planning and several days to set up.

(Oscar) Same thing, drop it in.

-The amount of time and effort that the office staff, both in Virginia and New York, put into planning of this show permitting, getting the site inspections done, this is all the lead-up to this massive event.

-Beautiful.

This one is ready to go.

Good job.

-For more than two decades, Grucci, The First Family of Fireworks, has worked its magic, illuminating the Vegas sky.

LVCVA spokesperson Heidi Hayes shares why this America 250 celebration really is an only-in-Vegas, must-see event.

(Heidi Hayes) Vegas goes big.

What do you expect from us?

This is a big celebration for our nation, and we really wanted to be part of it.

So we thought, fireworks.

And not just one night of fireworks.

Let's do eight consecutive Saturday nights of fireworks.

-Each Saturday, fireworks will be launched from three new rooftops.

Tourists and locals alike, treated to an impressive eight-minute synchronized show, all culminating in a spectacular Fourth of July synchronized display launched from nine rooftops across the Las Vegas Strip, expected to be the largest summer fireworks show in the nation.

-Very patriotic.

The music is going to be what you would expect for something as monumental as our nation's 250th birthday.

-This America 250 celebration, Vegas-style, really is all about teamwork and some fun collaborations.

-So iconic now.

It's only been here a few years, but everyone knows Sphere.

And so they're going to have complimentary Fourth of July programming, American-themed programming every Saturday night.

So as you see the fireworks at the different properties, you can also look at the Sphere and see everything that they're doing as well.

-From the world famous Las Vegas Strip to one of the world's marvels of civil engineering, Hoover Dam, America 250 being celebrated in very patriotic ways all across Nevada.

The patriotic display unveiled during a very special ceremony on Memorial Day.

-In thinking about America 250, there's no better symbol of America grit and tenacity than Hoover Dam, and we really wanted to showcase that in a way that's never been done before.

So there's an American flag the size of a football field draped across the dam, and also red, white, blue lighting.

And we just love the fact that that's just such a symbol of America.

-Hailing from one of the U.S.

founding states... -We're actually from Pittsburgh, Pennsylvania, on the outskirts of Pittsburgh.

-...we met Karen and Tom Schott, who were pleasantly surprised that their trip to Hoover Dam included this patriotic display.

-Wow!

You know, that's the biggest flag I've ever seen.

So, yeah, it was pretty, pretty nice to see that, yeah.

-Watching Karen and Tom from Pittsburgh, Pennsylvania, enjoying the beautiful America 250 display, you definitely felt the pride.

Why are you proud of being American?

-Just the freedom to go anywhere we want to go and do what we want to do.

And not too many people telling us what to do, just a few.

-It's just freedom.

It's just being able to, like he said, do what you want to do when you want to do it and, you know, enjoy it.

-You will be able to check out the Fourth of July fireworks spectacular on the Strip every Saturday until July 25.

Well, fireworks, not the only amazing spectacle that had people mesmerized and looking up towards the sky.

The Thunderbirds soared over Southern Nevada as part of the LVCVA's America 250 celebrations.

From their home base at Nellis Air Force Base, the Thunderbirds took off and flew over the Las Vegas Strip, neighborhoods, and Hoover Dam.

The Thunderbirds' next stop, Washington, D.C., for Salute to America 250 celebrations.

-How very cool.

You're going to be joining us again later in the show with another example of how Southern Nevada is being represented on the national stage.

Thank you, Maria.
