Bernie Goldbach in Cashel | Power cluster in the photo.
BACK IN THE 80s I had a job that put a premium on the thickness of doors, the shielding on power cables and the pressure rating of pipes. Consequently, I "read" power clusters like the one in the photo.
We had a fat manual that catalogued all known utility and communications infrastructure for Soviet and East German missile installations. I was part of an inspection team that monitored the tear down and removal of intermediate range nuclear forces (INF) from Russia, Germany, Sicily, and England. In some cases, total removal meant decommissioning communications, air pressure, and power lines that were shielded in hardened facilities.
At a glance during a short-notice inspection, we needed to be able to read the kinds of services that would work in a place that used to be part of an INF installation. Most of those buildings are no longer on active military installations today. Some of them would make interesting movie sets for the Bourne Identity franchise.
Bernie Goldbach has a highly-redacted spymaster
journal.
