Yeah, pretty much. A piece here, a piece there. Little pieces, mostly. Although about ten minutes ago, they just pulled another largish piece of a human body out of the rubble and gave it the flag-and-stretcher treatment. Every now and then, they do still find a mostly-whole body. But mostly they find pieces. Out at the landfill there are even more people than at Ground Zero, literally running the dust through sifters to find bone fragments. Every piece will be DNA-tested. Eventually we will know how many separate individuals were recovered at the site.
You really put any credence in the "take 220 storeys and do the math" method? That assumes that everyone in both buildings was "trapped" as though they were above the impact zone, like Cantor Fitzgerald, and that nobody was able to get out at all, even though they had almost an hour to escape Tower 2 and about an hour and forty-five minutes to get out of Tower 1. Yet this paragraph seems to suggest that 38,000+ people managed to die that day without anyone knowing about it, including the people themselves (they're at work, most of them, in the new offices their companies relocated to. They don't have a clue that they're really dead. Neither do their families and friends, who never reported them missing and continue to interact with them in a normal manner).
The only hope I hold out for this Chamish fellow is that there are quotes around the various paragraphs; so maybe these paragraphs in quotations are all wild-ass theories that various uninformed nutbars suggested to him during his travels, instead of this own "thoughts" on the subject. IF these are his own conclusions, though, he's a loon.
