The part of the Twin Towers that didn't collapse...

Discussing September 11th, 2001 and the building cores

[VS-etpn]

Pasquale Buzzelli was somewhere between the 13th and 22nd floor in that stairwell and survived. He was found so high up on the rubble pile the firefighters didn't realize he was a survivor and at first thought his cries for help were those of another firefighter searching for survivors.

I think it's a similar situation where... lost my train of thought.

Living only 10 minutes away and seeing plane 2 hit the south tower with my own eyes it was the most terrifying experience ever

I feel bad for young people who never got to see these buildings. I don’t think I ever went up to the observation deck, but I did go inside them in the lobby area. It was always amazing how you could see them peering up over all the other buildings when you were walking around lower Manhattan. You always knew where you were because of them, they were a great reference.

3:35 do you think it’s a similar situation?

2:07 the stairwells were in that core too. It explains why the vast majority of firefighters remains were found in the stairwells while other bodies were just tiny fragments

[JJRClassic]

Regarding the core remnants that stood for 10-15 seconds after the initial collapse, it looks like *everything* (bathrooms, rooms, elevator doors, stairwells, interior decor etc.) was totally stripped down to the bare structural beams. I doubt that there were any survivors within the higher-levels of the core during that short period of time. They would've just been washed away in the tons of falling debris.

Just imagine being in that one strand of remaining tower like 40 floors up just seeing both buildings collapsed around you and knowing your little core section is the only surviving piece

[minnesotastatesirens]

its so eerie, just the skeleton of a building standing where one of the most iconic buildings stood.

3:36 Im not a proffessional, But i think theres a similar situation there.

[VeeTravels]

Hey thanks for the detailed video. Although, I think there is an audio glitch at 3:35 where you say "I think it's a similar situation where..." 3 times.

[GARdotETH]

Stairwell B around the 6th floor is I think where Josephine Harris was with 5 or 6 firefighters who all survived. I think they were the only survivors in that building.

5:55 The perimeter columns are there, and the core is there, there is just no internal divider walls installed to make up the offices, just completely empty floors, hence the transparent look, which is certainy consistent with what you'd expect. Most of a buildings structure provides is empty space!

3:36 I think it’s a situation where, i think it’s a situation where, i think it’s a situation where 💀😂

It is crazy that they managed to still stand for a moment after the main collapse.

[Justyburger]

I'd seen various videos of the cores remaining and then falling down afterwards. I always felt that they looked like vertebrae and were definitely haunting to see. I'm surprised that those cores didn't remain up indefinitely after the buildings collapsed.

[OscarLopez-gwjx]

it's so sad that when you see videos such as the planes hitting the towers, or the towers collapsing, you're watching hundreds of people die instantaneously... horrible
2:33 i'll say it for you... the core look like vertebrae or bones

[austinv]

At 6:44, you mention a 40 minute video that showed the devastation between the South towers collapse and the North Towers collapse, is it possible you could link that video or share the title?

Thank you :)

I don't think anyone could have survived inside the core, even after the collapse because the columns and bathrooms and everything else were surrounded with sheet rock. Not concrete. Given the forces of the collapse I can imagine very little surviving there. And you're right about it being hard to see from different angles. First time I saw the North Tower core I thought it was the corner of the building, but knowing how it was built it can't be anything else than the core structure.

I wonder, if they had been able to sparsely use heavier I beam girders between the core and perimeter, and used a better L flange to anchor the truss to that perimeter. Maybe the towers could have stood longer. Had the core been surrounded in concrete maybe the stairs would have been passable. Maybe the whole thing wouldn't have tumbled down the way it did. Even with this all said, no architect or engineer at the time ever envisioned a plane intentionally crashing into those buildings at full throttle and with a near full fuel load.

The reason why that staircase survived was because it was partially reinforced after the 1993 bombing. This is why this particular section survived

EDIT: Also, in the picture where you can see the sunrise go through the towers. The South Tower is the one on the right. North Tower is on the left. You can tell because if you look to the lower left of the tower on the left you can see buildings 5 and 6 below it
