That's what I thought as well. I was thinking that Aerial Tower 1 would get it and their rig would replace the older spare. However, there is a photo on chicagoareafire.com of the rig numbered as Aerial Tower 8. There has also been a confirmation by a member of the CFD that it is indeed AT8. So, AT1 is not getting the new rig.
