That case is from 2005. IIRC (and I did see it under construction) the WTC was built in the late 1960s/early 1970s, so I'm not sure how relevant that case might be.
Were there any lawsuits regarding eminent domain over the building of the WTC prior to its construction? I have no idea, but the 2005 case wouldn't even be relevant to the rebuild after 9/11.
Such takings of property under eminent domain had happened before; it was not a new idea in 2005.
This case was the result of a suit against such takings. The suit failed, and the takings continued.
how could eminent domain have been used to make place for the world trade center? Wasn't it just offices?

Back in de 80's, to double the data on a C64/1541 floppy disk, I used a hole punch to create a hole on the other side and flipped the disk.
I replaced the write-protect sensor with a toggle switch.

There was a time, not long ago, when new products were built on new ideas, and the marketplaces were very, very heterogeneous.
Now, the marketplaces are largely commoditized and new products are incremental improvements and extensions of previous ones. The old ideas and products are still there, fascinating history to be explored.
An example - on a new Linux system, look at the man page for "termcap", and you will find configuration data for the Teletype model 33 and the Lear Siegler ADM-3. That makes people like me go "Hmm!" in a fascinated tone of voice.
History is like dead reckoning navigation. We only understand where we are by knowing where we were and what was done to get from there to here, and there are those of us very interested in such things.
This is only a partial answer to your question.

It's more complex than that. There factors other than drag. Planes wouldn't be more efficient if they simply used roads at 60mph all the way to the destination (no takeoff)! Fuel is expensive so they do a lot of work to figure out the optimal speed.
Use roads at 60mph? I guess they're most efficient if they don't start the engines at all and you put the plane on a boat or a train.

Jet aircraft typically already fly at their most fuel efficient speeds rather than their max speeds
No, they typically fly at the most profitable speeds within the constraints of the flight and airspace parameters. Which results designing the planes to be efficient at those speeds.

Realizing that there are other issues with which to contend, why not just start slowing down airline flights?
Drag, and therefore fuel used, is a function of velocity squared. https://en.wikipedia.org/wiki/Drag_(physics)#Aerodynamics
Slowing down from 500 to 400 knots adds a half hour to a 1000 nm flight, but could provide maybe 25-30% fuel savings?

If you watch an old Saturn V launch video, they have the same slowness at liftoff. Really gives a sense of of how gigantic the thing is. You've stuck rockets onto the bottom of a skyscraper and are trying to loft it into the air.
