The below image is one that I had seen 6 months past, knowing that I was looking at the core but not knowing exactly what would make identifying it easy.
rumpel had posted a thread and philb brought word of it to me, I saw the image and realized I had seen a photo of the other side of the same structure, found it and began looking at it again. I posted it with the image of the other side.
http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=125&topic_id=56852&mesg_id=62255Then recent discussion about rebar has had me looking at that image, now I’ve spotted the 3” rebar. Classic highly stressed bar, coiled lightly from such severe stresses, come from the top of the core wall in the image above. There are a number of them all having the same very rigid coil.
More evidence for the cast concrete core.
More 3” rebar from the core of WTC 1
Here is an interior box column to establish scale and estimate the size of the fine vertical elements with the slight curve, above. The photos are a sequence and this is the first.
The steel reinforced cast concrete tubular core of WTC 2.
Here is the spire from a different angle that shows the concrete wall of the core.
Here is zoomed and arrowed to identify its parts.
Below is the top of WTC 2 falling onto WTC 3. Inside the perimeter box columns is a brownish, gray structure, the concrete core.
The concrete core is not a theory for me. I saw a documentary in 1990 that had all the detail needed to fully know how the building was built. It was 2 hours on PBS.
Ask everyone you know if they saw it. Ask them if they remember what the core was made of.
I noticed that the forum lacked a focus and something tangible to discuss. I began a series of threads, the one you read is the most recent.
Here is the first.
Then the simple fact that no explanation for the non appearance of the supposed 47, 1300 foot steel core columns in the collapse EVER has been posted prompted a new level of assertion that the core was concrete was justified.
To be sure that there was a competent description of what high explosives look like when they are used to cut steel I created a thread. Very few posted there so I explained what 47, 1,300 foot steel columns would look like being cut by high explosives.
Here, now, ........... I’ll say that steel would be flying through space for near one mile. Manhattan would get shrapneled with heavy steel structure traveling at 5 miles per second and be mostly leveled. There is no raw evidence for the steel core columns.
