Sharpening a pencil on a lathe - GIF and comic

WmRMeyers hit it on the head; starting with what makes ISO look infantile "Must order from a vendor that ensures all the standards are met by a manufacturer who meets those standards". It's known as MIL-SPEC MIL-STD. Individual services have amplifying requirements, as they operate in different spheres. ie salt water corrosion differs from that occurring in space.

I can relate exact same conditions;
handling and living on the first NUCLEAR CARRIER,
building the world's best tape recorders THE ONLY ONE SUITED FOR SPACE LAUNCH_FLIGHT_ENVIRONMENT_RECOVERY, 1" reel to reel BTW,
all kinds of SPACE SHUTTLE COMPONENTS,
and top of the heap WORLDS SAFEST [yet incredibly destructive] PRODUCT.

A great failing of cable show "How It's Made" neglects more important "Why It's Made", and "Who It's Made For".

Man-o-man, got my rant hat on today.
