I haven't read it yet, but even the table of contents gives some clue as
to the degree of detail it goes into, with investigations of the effects
of thermal heating on the soles of the astronaut's boots.

Then there's this bit, which I discuss slightly he http://up-ship.com/blog/?p=1570

"
The hold-down cables on each neck ring were severed at the attach
points to the cable guide tubes due to
mechanical overload (figure 3.2-24). Most cable guide tubes
experienced significant plastic deformation.
The guide tubes display evidence of external contaminants (i.e.,
melted metal and suit material) and thermal
effects on top of the fractures and localized deformation. This
indicates that mechanical loading preceded
exposure to the thermal environment. Rotation of the helmet relative
to the normal forward position was
observed on all neck rings varying from 90 to 180 degrees. Major cable
guide tube deformation and
helmet rotation indicates that a significant loading event occurred
where helmets were removed via
a mechanical (nonthermal) mechanism.

The helmets were twisted off of the suits. While described clinically,
it reads like a horror story.
