How pissed off would you be as a construction worker that built those?

[JackAnderson]

The fact that they took so many years to build and only 12 seconds to come to the ground it’s just crazy. I would be so mad if I was one of the people that built that.

[kongchingpow]

My mom grew up in NY and watched them being built over time...then she watched as they were destroyed. Surreal, at the very least.

Finally a US engineering docu that mentions the aussie engineering that enabled it! This has triggered my engineering dad all throughout my years as I love watching engineering docu's and my dad always calling out the show for not acknowledging an Australian enabled that build to happen lol

My brother was with the Crew that installed the electrical system, and the elevators

They were actually designed to withstand the impact of a plane according to the head architect

I worked in N.Y.C. for 40 years. In the '70s I had a 45 min. commute from N.J. & I watched the Towers go up. In the '80s & '90s the Towers were my compass for finding 'South'. I saw them collapse as an eyewitness from my recording studio's roof.

This world no longer exist anymore, it's not just the towers.

The major flaw was that they used steel instead on passport paper.

Its not a Kangaroo Crane, Their Favco Diesel luffing cranes. Yes they are Australian and can climb up in a number of ways. Today its preferred to have them external and when external they can climb themselves back down. When internal of a building you need a recovery crane to dismantle.
Yes the Aussies are brilliant and smart. Also the only nation to have supported The USA in every war its fought since Australia was a nation.
God bless America and Australia

What a unique invention of amazingly strong steel that also disintegrates, evaporates, and turns into dust!

The world Trade Center changed how buildings were built.., and was the very first to forever change how buildings come down as well!!..

An engineering marvel…

[tausa]

I’d never heard about the kangaroo crane, or known how they work. Subscribed - you have very interesting content, well explained.

[Jimmy_Hopkins]

To think for such massive tall buildings it only took 5 years to build and 10 seconds to come down.. unbelievable

[MichaelMencher]

Truly fascinating. I'm originally from Astoria Queens NYC. Miss the Twin Towers, but the New Freedom Tower is a Tank! ♥️👊!

[michaeldriscoll]

I remember when they were being built. This was my playground 🙏💖💝😘🌹💯🙂👍

[myplaxismodelisbetterthanyours]

It's amazing what men can accomplish around the globe

[headroomdave]

These engineers are unbelievable Brilliant

[jahmeer]

R.i.p to the people and the legendary buildings. I miss seeing them in the skyline.

As a union ironworker, , 3rd generation...i appreciate this video ...ive spent the last 28 years building skyscrapers...people ask what i do ...they dont truly understand ...this video gives a glimpse into what i do ....thanks ..local #79 norfolk, VA.

My Brother and I were there in 1973 as kids saw last sections lifted .
