Nothing in the Rules says that someone can't be called into an FCC
office and administered an individual test if the FCC deems it
necessary.


An FCC field guy (that you know of) decided that a wife
of a friend of mine needed to be retested on 5WPM code.
At the time (early 70's) the FCC test office rarely if
ever did 5WPM, and the examner had to dig up a 5WPM
paper tape (with punched holes). Seems the tape was
bad and the machine sent trash instead of code, but the
examiner himself didn't know code and decided that she
couldn't copy code and failed her. "Broken tape machine,
yeah sureeee....."

If the tape were played backwards (a code machine my
father used used two spools, a supply reel and take
up reel) it would produce some copyable characters
(A for N) and others would be trash. Someone forgets
to rewind a tape, and later someone else plays it for
a test. Sounds like code to someone who doesn't know
code.
