Step by step.

Nik Wallenda walked over the Masaya volcano in Nicaragua.

Absolutely spectacular.

Look at the sheer Majesty.

They call it the mouth of Hell, and you can see why.

Well, Linda had to wear a gas mask because of the toxic fumes emanating from below.

Is there any moment where you said I don't know if I'm gonna make it?

I can tell you that there was one point where my mind said, Am I gonna have to go down and hold onto this wire and wait for help?

Very strong draft right there.

He practiced in 90 mile an hour winds.

And boy, did he need it.

It was like being in the middle of a hurricane.

It was cold at times.

It was hot at times, but the wind was just so wild.

There was one point where I tried to take a step forward and hit me so hard that it actually pushed me backwards.

This is easily the most difficult.

Dangerous.

His wife errand era also braved the volcano.

She even hung over the lava lake by her teeth.

An active volcano by nothing but her teeth.

you could see Nick really sweating those last few yards.

So, Nick, how are you gonna top this?

What's next?

Can't top that.

No one in the world, in my opinion, in the wire walking world could ever top what I did off the wire into the history books.
