Are new modules added to the ISS permanently hooked, ie bolts, etc,
after docking collars are joined? Also, when the ISS is deorbited,
will the modules be seperated before reentry to ensure better
destruction. |

There aren't docking collars. The CBM's use bolts.
It won't be separated, no way to do that |

Is this described/visualized anywhere? I've never seen specifics about
this process. Does someone manually insert the bolts from the already-
pressurized side? |

CBM allow modules to be berthed and unberthed. There is an active and a
passive side. The active side has motors that drive bolts to secure the
two modules together. Once done, the motors are removed, and connections
between the 2 modules are made.
Motors can be put back, connections undone and modules unberthed. This
is done with MPLM whenever ther are berthed and unberthed. It was done
with PMA2 and PMA3 which were relocated. And it will be done with the
KIBO logistics module that will be temporarily berthed to Node2 and
later to the main kibo module. |

That would be a gigantic task to unhook everything, requiring lots of
EVAs, even with DEXTR around to help.

Ok, maybe a mad idea, but what about the last crew on board leaving a
fuel air explosive device inside the station? When the crew is on the
ground and the station has dropped to the entry interface, mission
control could remote detonate. Ok, flame on  |

They're electrically driven.

Easier just to make sure that it reenters in the Pacific Ocean.

True. I was thinking of whether there would be some uncertainty with
regards to the drag in the outer atmosphere with respect to the solar
maximum around 2022, and the fact is may be better to break the
station up into smaller pieces. Seriously, has it been decided yet how
to deorbit the station at the end of it's life?
I did have a quick look on google and this is what I found:-

There is also talk of using an ESA ATV

I know ;-)
PS Are you finished with Mr Maxson now? |

Just as mad as Babylon 5 which supposedly represented a taffic obstacle
at the end of its mission, so they blew it up into a million pieces of
space debris 
Should of waited until it was at entry interface Draal may have
been a bit peeved at the debris bombardment though... |

Progress or ATV will fire their engines to slow the station down. (or
alternatively, if they still work, Zvezda will fire its own engines)
As the station comes down, it will likely break up into separate pieces
all by itself, genearing nice fireworks over the pacific and perhaps a
few pieces may reach water,i just like Mir did. |
