The USA is mostly empty space. Trying to force upwards in such an already dense area just doesn't make sense. We are not constrained the way singapore is.
Spreading out requires more non-foot travel to get places. Density means things can be closer.

#24I'm not an expert but those look like pretty wimpy columns? Kind of surprising, when I worked in a tower it had exposed concrete columns that were very thick in comparison
They are buckling because the floors and ceilings are bending!
Scroll down and there is a picture of a much thicker support pillar, though still seems thin? Maybe just the context in frame doesn't do it justice.

Not if you make the strings different lengths.
In that case the helicopters lower in the pecking order will chop off the strings for the higher ones. I thing seagulls is a better idea, if it worked for a giant peach it should work for a building. Plenty of those around and they'll work for peanuts.

#26They're adding a hunch of floors to an existing building - it was the old Pfizer headquarters and they want to turn it into apartments. Someone either didn't do the proper engineering study, or the original specs weren't accurate. Figuring out who to blame will probably take years in court.

Seeing how elevators are akin to vertical subways I think that problem goes both ways.

#28Does anyone here have any knowledge of how something like this gets resolved?
Most likely the building gets stabilized and then anyone involved gets embroiled in lawsuits and it stays standing half finished for years. One Seaport is a famous recent example of an under construction skyscraper getting halted for structural issues. https://en.wikipedia.org/wiki/161_Maiden_Lane

Tie every helicopter you can find to the roof, gas the bent bit off, haul it away and drop it somewhere? They'll likely shore it up with hydraulic props - probably going through the floor and ceiling to floor slabs above and below - to stabilise it, and then start demolishing the building bit by bit.
When you run the mental model of picking up a building with a bunch of surplus Hueys, do they not all collide together once they start bearing weight?
