I took a look at the film and it evoked several feelings. Some of them were:
a) If the Navy need to show this 60 years old instruction film to their new recruits,
maybe they need to do something about the material they chose them from.
b) If measurements are so important (and I am sure they are) why keep the so
called "Imperial system"? The rest of the world (but for Burma and Belize I think)
are using the SI units for good reasons. Then their Mars probes may even work,
if they launch any! I better not dig too deep in this...
c) The film hints at the use of primary, secondary and tertiary standards. With modern
instruments, that is not necessary the way it is done any more. You buy one meter
(for the unit) and it is good enough by itself to measure up the devices to be tested.
All the best,
