I suspect that it would be very difficult to remove the old foundation 
with a crane.  You're looking at roughly 3 cubic yards of concrete 
weighing roughly 10,000 pounds (not to mention whatever drag/suction 
there might be), and I can't imagine the tower base stubs being enough 
to lift that sucker out of the ground even if you thought it would hold 
together since it doesn't have any rebar in it.  If it needs to come out 
I think your only recourse is to somehow break it up ... jackhammer, 
expansion goop (don't remember what it's called), or dynamite.

Good luck es 73,
