Let's see.  The towers were 95% air when they stood.  1368 feet*.05=68.4
feet.  Of course, the mass of the towers won't pack down with no voids
in the rubble, and that will increase the height.  On the other hand,
much of the debris fell outside the footprint of the base of the towers,
covering more area, and that will decrease the height of the debris pile.  
As an approximation, we can say these two effects pretty much cancel and
we're left with the original figure of close to 70 feet deep.  That's the
depth of the bathtub so we'd expect the pile to reach close to street
level or the original plaza level.  And guess what?  That's the level
of the debris we see in that picture of all the debris that you keep
harping about!
