They started to take down the netting last week on the one corner so we still have lots of time.

i cant believe they went with a SOFP system instead of an intumescent paint for the podium plate columns

kinda terrible.

Are 2, 3, 4 wtc as strong as 1? As in can they withstand a plane as 1wtc likely could?

I'm pretty sure the red pain is intumescent, so apparently they are just adding another coat on top.

Idk everyone's still stuck on the Spire. To be honest the only people who care whether its cladded or not are the skyscraper fans and such. New Yorkers will only notice the building it self either which way whether it be a spire or not. Personally I think the antenna works better there was just to much weird shapes and angles on this building before some of the changes. The base
is also deff an upgrade it should have been squared from the start.

Good question. The other WTC towers probably aren't as strong as 1WTC however I believe that they are still far stronger than your average supertall

This is in no way supposed to be offensive, but if a boeing 767 crashed into the upper floors of 1 wtc wouldn't there be more damage because of the taper of the building?

So, the current row of glass is almost complete correct? And then one more row is left until they reach the mechanical floors right?

There are no stupid questions, if worded properly.

Yes and no, the structure is not as heavy there, it doesn't need to support as much weight, so it is not as strong. This means that the area directly surrounding the impact site may appear more damaged than an impact area lower on the building. On the flip side, a lower impact would look less severe to an untrained eye, but the repairs would cost exponentially more because the entire load path of the column from that point up could be compromised along with the connections above. Would this cause total structural failure: no. Hopefully this is never put to the test.

One thing I would like to add is that the structure of 1WTC has a major advantage in that it focuses so heavily on its core. The Twins had their focus pretty much balanced out between the perimeter and core. It is easier to pierce through two standard thickness layers than through one double thickness layer.

Also, the steel of the Twins focused heavily on quantity, rather than quality as was witnessed with how many columns the perimeter structure had. Again, it is easier to punch through more thinner columns than through less thicker columns.

Finally, what caused the Twins' downfall was the fact that there was no major structural element connecting the perimeter to the core, only basic trusses that were very vulnerable to fire or the impact of the planes. Old buildings had a grid which minimized the chances for problems due to disconnection of the individual elements (not that the connections wouldn't be important, it's just that there was not such a long area without columns). Bundled tubes had a larger scale grid of massive walls of steel columns making the connections between the tubes very strong. the tubes of the Twins had only their trusses to keep them together.

Btw, another huge advantage of 1WTC is that it has a concrete core. Concrete is far more resilient to fire than steel. Steel, even if it doesn't melt, is still weakened a lot by fire.

Final note, if anybody has more accurate knowledge about the mechanics of a plane crash into a skyscraper please feel free to correct me. I'm always glad if I can learn something

They repositioned three of the Earthcam cameras and have the same view of WTC 1. Now we get to see a huge portion of the building, but not the top. We will see what they do with the Tower 1 zoom cam tomorrow. It looks like it is still showing an image taken earlier this morning in the fog.
