"    A friend had some trouble with some mil spec stuff.
     He had started with the same assumption, then,
     being an engineer, investigated.  He found that the particular
     spec required high reliability for 'one war'.  (OK: it
     was  phrased differently.  Some mil specs have a 'mission time'
     component.  Reliability for one mission time is critical.
      Reliability AFTER that is not.)"

	The modern criterion is "probability of mission success" and the MTBF
required of any particular component of a complicated system in order
that the overall system meet is reliability goals from which the
probability can be calculated.  If you do a Google search on
"reliability" and "MIL Specification" you'll be overwhelmed with the
literature you turn up!
