Note entrance to underground in center of photo.  Just to left is air intake grate
and to the left of that is bomb detector.  The Finland site was the Emegency Relocation Site
for the Philadelphia Bell System headquarters
 

Microwave equipment building (2 PSI) with tower with TD-2 horns.  It was in this
building that Bell System excutives would meet during an emergency.  As of 2000 the
old chrome and vinyl chairs and the old four pin telephone jacks and KSU box still
exist in the basement of this building.
