SA,
Nice job ignoring everything that I wrote.
Or you could instead take 2 cinder blocks and place one on the ground and lift the other one up say about 15 feet and drop it on the other one. What happens? The block you dropped gets smashed and takes more damage than the block that was lying on the ground.
.
On what basis do you make this assertion that the falling one gets damaged than the stationary one.?
.
So now can anyone tell me why the soft mushy human bodies would react differently than the cinder blocks?
.
Cinder blocks are brittle aggregates.
Humans are composites of soft (muscle & fat), intermediate (tendons & ligaments, i.e., collagen) and hard (bone) structures.
.
That's how the JREF cult dishonesty works. Say something that seems to make sense unless you actually think about it and hope no one will think about it.

Wrong, Steve. If you want to discuss what is really happening, feel free to respond to this post, in which I presented a general approximation to what must have happened.

The short version of why the collision preferentially destroyed the lower portion rather than the upper block is:
1. By the time the upper block hits any floor, over 2/3rds of that floors supports have been destroyed. The remaining 1/3rd is massively damaged.
2. as soon as debris is knocked free from the structure, it begins to fall. When the upper block collides with the debris layer, the relative velocity is the falling block velocity minus the falling debris velocity. When the debris layer collides with the lower block, the relative velocity was the speed of the falling upper block. The collisions with the lower block are more energetic and more severe than the collisions with the upper block.
3. the initial failure turns one entire floor (the 98th in the case of WTC1) into debris. Plus 2/3rds of the 99th & 97th. Plus 1/3rd of the 100th & 96th. The 99th & 100th floor debris falls WITH the upper block. The 98th, 97th & 96th floor debris falls AWAY FROM the stationary remaining structure. The initial collision is the 99th floor, plus the weights of the the 3 to 6 floors above (transmitted thru the columns) landing on the 1/3rd remaining 97th floor.
4. the debris impacts into, and provides support for, the upper structure. This happens over the course of about 3 to 6 stories of fall. After debris fully impacts the upper block, then you really do have the entire upper block (13 stories plus X floors of debris) impacting each top floor. When these impacts occur, each top floor is already 2/3rds destroyed.
5. the debris builds up underneath the upper block, and protects it from the collisions, which happen at the BOTTOM of the debris layer, while the upper block rides down on the TOP of the debris layer.
These are the reasons that upper block is protected from destruction, while the lower section is not.
I'll wait to see if you have a cogent reply. Or if you just wave your hands and ignore all of this.
