[@kingsand999]

Great video. One correction - the building getting narrower towards the top was not an aesthetic choice, it was a legal requirement. After the Equitable Building was built downtown, all skyscrapers had to have setbacks if they wanted to go higher. This was done so that the buildings would not block the sunlight from hitting the streets. More info here - en.wikipedia.org/wiki/1916_Zoning_Resolution

[@allenkatz5652]

The zoning law states that the hypotenuse of a right triangle drawn from the opposite side of the street with a 25 degree angle or so can not touch the building which is why the building needs setbacks every few stories on the lower level. The exception to this rule is that 25% of the lot size can be built as high as technically possible. (This explains why developers buy air rights from neighboring plots.) The last setback the Empire Stare Building needed for the zoning law is at the 29th floor. The shape of the building above the 29th floor was to make 8 corner offices while using exactly 25%of the lot size. The floors above the 86th floor observatory were intended to be a mooring mast for dirigibles but the plan was put on hold and scrapped after the Hindenburg accident.

[@keithdiaz5081]

Yes, but they used that as part of there design element towards aesthetic. It was all thought about.

It was built in 13 months around 90 years ago, no computer aided design, none of the technology we have today. It also was built ahead of schedule and under budget. Compare that to the 6 years with all our modern technology it took to build the new Wembley stadium, which ended up way over schedule and much over budget. How is this possible?

[@HobbyOrganist]

As I remember back in the 70s, they had a glass showcase with a brick in it, and if I remember right it said they had ordered either 10 million or 100 million bricks for the building and had ONE brick left over! Those terra cotta blocks used in the floors were commonly used back then in partition walls and elsewhere, they were why the gothic styled building at 90 West Street which had raging fires after 9/11/01 survived. They still use these blocks to-day in home contruction in Romania, Slovakia, Hungary, and I imagine elsewhere in Europe. I saw google street views of a new house under construction in Hungary, it used those same terra cotta blocks which were then faced with stucco, while the roof was made with red terra cotta roofing tiles. They are superior to the cheap concrete blocks we use- larger in size and having multiple cavities in them, they have more insulation value than concrete blocks, and since they were clay that was hardened and vitrified by FIRE, they stand up to a fire whereas concrete blocks crack and crumble because concrete is made into a powder by grinding up and burning limestone, adding water and sand to that chemically cures it into a hard form but it's not vitrified like terra cotta

[@Pagasonic]

A tiny plane crashed into the empire state building, but a massive plane going full speed crashed into the twin towers.

[@davidlane180]

No, you are simply mis-informed. The plane that crashed into the Empire State Building weighed 33,500 pounds with a maximum fuel of 974 gallons of fuel traveling at a maximum of 275 mph. The 767 that hit the WTC weighed 284,000 pounds, carried 12,100 gallons of fuel and were traveling in excess of 500 mph. Spot the difference. Not being able to comprehend that makes it redundant for me to explain the difference in the construction of the 2 buildings.
