The thefts were really odd considering that these
recorders were
connected to an array of Pt-Pt+10% Rh thermocouples, each about 4 ft.
long. The metal in one of those was probably worth almost as much as
a bucket of those silver beads. Yet they were never filched.
The thieves may have been smart - Platinum is harder to sell on the
open market, while gold an silver can be sold almost anywhere amongst
zillions of other deals that act as cover (or "noise").
