The airplane that hit the ESB in was a WWII bomber (a B-25?), which is a fairly small, lightweight and slow-flying aircraft, especially when compared with today's commercials, similar in size to one of today's larger 'puddle-jumper' turboprops, and had a light fuel load - they were arriving in the NYC area and literally got lost in the fog on their way in to a local airfield.

The damage to the ESB was amazingly light that weekend and the building opened for business as usual the following Monday.

Isn't the ESB's structural steel encased in concrete (for fireproofing)?

Also, Tag is correct in that the steel in the WTC towers did not melt, but was severely softened by the heat of the resulting fuel and 'office stuff' fires. The fireproofing insulation was suspect, too, but most of it in the crash zones was blown off of the steel by the impacts. Without that insulation, which is usually good enough to allow plenty of time for firefighters to control normal 'office stuff' fires, the buildings didn't stand a chance. That they did stand for as long as they did, long enough to allow for most of their occupants below the impacts to escape, is a testament to their design engineers.

NOW - Back to the site redevelopment.

OK people. This is getting ridiculous and you are all getting off-topic. Good thing I am not an administrator cuz' I will totally close this one and make a clean one instead. I can't believe you are discussing another 9/11 event again. Buildings will collapse by any means and not only by airplanes. Even Rosie O'Donnell can do it just by opening her mouth. OK, that last sentence might be too harsh

Amazing building site, very brutal. The design of these buildings are great too. Sad about the way the wtc went down, but the new buildings will look way better

I don't think it is getting off topic. The construction of this new tower has alot to do with the survivability of the old buildings. The Old Twin Towers getting hit by them planes should have never have happened. Awful thing but the engineers have learnt a great deal. If we can't make comments on the old towers we can't comment on the new construction of this tower. Construction comments comparing the two aren't off topic. Its totally on topic.

GROUND 'ZERO TO 60'
WTC TOWER WORK SURGES AHEAD AT LAST


By TOM TOPOUSIS

September 5, 2007 -- What a difference a year makes, even at Ground Zero.

Once dogged by bitter fights over how to rebuild the World Trade Center, construction there is finally booming, with more than 600 hardhats pouring concrete, blasting rock and raising steel in a bid to fully rebuild the site by 2012.

The Freedom Tower - the first skyscraper to rise at Ground Zero - has reached street level with the setting of jumbo steel beams that will form the below-grade base. Next year, the tower's frame will begin to rise above street level.

Alongside the Freedom Tower, hardhats have built 121 out of 150 concrete footings for the World Trade Center Memorial and Museum, with steel expected to be shipped in later this year to begin raising the memorial to street level.

The $2 billion transit hub designed by Santiago Calatrava is also under way.

Perhaps the least heralded project at the site is the massive, 80-foot-deep excavation of the eastern half of the trade center to create a watertight "bathtub" for three Church Street office towers.

Most of the work began after last year's agreement between Ground Zero developer Larry Silverstein and the Port Authority, which owns the site. The bistate agency is in charge of the bulk of the project, with Silverstein concentrating on three towers.

"We've restored a level of confidence to the rebuilding process and that's translated to the marketplace," said PA Chairman Anthony Coscia.

He said that the reconstruction project has helped fuel renewed interest in the downtown office market, where demand for space is booming.

"These buildings will be built and the site will be restored," Coscia told The Post during a recent interview.

Added together, $16 billion worth of construction will take place on the 16-acre site, making the World Trade Center the most expensive and most complicated construction project in a city brimming with tower cranes.


Because so many projects are being squeezed into the site, each one is linked to the other through shared subterranean structures - from piping to concourses to underground railroad and subway lines - further complicating the work.

"It's not an easy project to build," said Coscia, who likened the engineering effort to building a "subgrade Rubik's Cube."

Construction so far is mostly limited to the western half of the site, inside the 70-foot-deep bathtub that was built to contain the foundations of the Twin Towers. A second bathtub is being excavated on the eastern half of the site for Silverstein's towers 2, 3 and 4.

Silverstein, who last year completed World Trade Center 7 just across Vesey Street from the WTC's main campus, expects to begin construction of his three towers in 2008.

"You ain't seen nothing yet," Silverstein said.

His design team of 120 architects and engineers has been working at a studio on the 11th floor of 7 World Trade Center.

"We will hit the ground running when the sites are handed over to us in January," he said.

One setback for the reconstruction is the fiasco at the Deutsche Bank Building, which is being taken down by the Lower Manhattan Development Corp. a block south of the WTC. Two firefighters died battling a blaze inside the toxic tower last month.

The Port Authority, which will take over the Deutsche Bank site once the tower is removed, has an agreement to sell it to JPMorgan Chase as a fifth WTC tower beside a park and new home for St. Nicholas Greek Orthodox Church.

Yeah, let's keep to the structural questions, please.

beautiful image - great to see the Freedom Tower floorplates starting and heading upwards. Shame my visit in December is a year or two early really! That's a fantastic cluster of towers - biased as I am, the Foster and Roger's towers are stunners!

The Transit hub is a joke, it looks like a giant dead fish. In my opinion, they should replace it with a tower and have a hub below it.

No Bias necessary -- Two and Three will definitely be the prettiest buildings there!!

As for the thing hoping to be built . . . don't you think it's funny that they're patting themselves on the back for getting this done . . . ELEVEN YEARS after the whole ordeal happened?!

Haha, nice! You should see what I've drawn during my college writing course. I have over 100 sketches of towers I made and the WTC and downtown and midtown and everything in between.
