The fact that WTC7 does appear to have collapsed from the bottom
and so soon after the fire people withdrew is somewhat puzzling
though, the lower floors should have been water logged which
should have cooled the steel framework.

Water running down stairwells away from the fire is no indication
that water was necessarily running down structural beams in the
middle
of the fire as well.

That is true. It would tend to flow most effectively down the most
convenient path. However water should have collected more
effectively lower down the building as it accumulated from above
causing whole floors to become water logged.

Waterlogged floors below, assuming there were any, have no effects
on fires raging on dry floors above. I don't see your point. The plane
hit probably broke pipes. This will also result in water runnings down
stairwells. This is also (possibly) that much less water available
for sprinklers.

Well I think the point i'm trying to make is water falling from above would
tend to collect lower down, and thus keep the steel stutcture cool. Of
course WTC 1 and 2 fell from the top as one might expect.

 I know in one of the accounts I read a group of people
escaped into the subway station beneath and it was mentioned quite a
lot of water was falling through the ceilings, by the time they
actually escaped through the ticket barriers.

Was that after the collapses occurred? This must also have caused
the rupture of a few water pipes. Whatever the case may be, it is well
documented that the sprinkler system was severely overloaded where
the fire was raging and that there was next to no firefighting effort,
most
operations being focused, sensibly, on rescue and evacuation.

No it wasn't after the collapses occurred the account I read was of a
survivor. I think the collapse of the towers followed fairly shortly after
he and a few others got out, he said he just started running and didn't stop
until he was miles away.

Generally I would think water would tend to collect more in the lower floors
but. I dare say the weight of the building above would have snapped the
steel supports in any case.

I must admit I am a bit sceptical about the controlled demolition theory.
Given the amount of damage in some parts and water everywhere I don't see
how a "controlled" demolition could have worked since there would be no way
of undertaking a controlled detonation with so much damage everywhere.
