I agree that the comparison with a plane crash might be wrong (I felt it would be worse due to the dangerous terrain and jet fuel involved in many circumstances), but still isn't it taking unusually long to pull out bodies/survivors? Maybe it symbolizes how rare the event is, but I would usually except more by now.
The Murrah Building Bombing took many weeks to recover the victims. Might know a little about that event.
I don't think you understand the frailty of the human body. 55% water and a bone structure to support less than 300# roughly. People break ankles stepping off curbs.
Tens of thousands of pounds of structural weigh on top of a body pretty much exceeds the limits of the skins ability to contain fluids.
The bone structure will fail miserably considering there is enough mechanical stresses during the collapse to break structural concrete into pieces the size of softballs and soccer balls.
You would have to be lucky to find a body that might happen to have been a location within the structure next to a support carrying beam that would shield them.
The recovery team will soon be in hazmat attire as time an temperature takes its toll.
As I mentioned in an earlier post a friend who owns a structural engineering firm declines to get involved with high rise condos due to legal liability. Another engineer friend noted that it is not possible to build a high rise without subsequent issues.
This legal liability becomes a major issue. When you can not inspect during the construction phase it is pretty hard to determine size and positioning of rebar in a concrete beam or other issues years afterward. I am not sure that they will find anyone to inspect in a timely manner or certify the buildings. My guess is that it will have to fall internally within the AHJ or somehow someone will have to set up an LLC.
