Not feet into tenth, but with inches divided into 1/5, 1/10, 1/3, 1/6,
1/9 and 1/12.
I've seen one with foot divided into 1/3 and 1/4.

I think it might be industry specific rule.
About 30 years ago. My boss, offshore, took some measurements in the
toolpusher's office using a rule he found there. After getting whatever
it was made. It did not fit. He got a bit of a slagging for it. As you
would. ;-)
He went back up to check only to find that there was 10 "inches" to the
foot.
Drillers use some strange terms. The anchor chain tension is measured in
Kilo-pound-inches. I had never heard of that measurement before I had to
calibrate the load sensors.

I have a triangular drafting ruler that is like that.

Interesting story. "kilo-pound-inches", could that mean 'thousand pounds
per inch'? the word kilo being used for the thousand's value?

Yes kilo is a multiplier and since it is a unit of work it should have
been KIP, kilo inch pounds which is 112.98 Nm.
I got kpi stuck in my head. :-)
For something so important the transmitter was a simple op amp. Check
the zero and span against the supplied load cell manufacturers data
sheet. Easy peasy. :-)

Easy peasy indeed. I imagine the guys calibrating those data sheets:
"Hey John! Lets give it a pound more!" BANG! ;-)
I am always surprised that we got to the Moon at all, or Mars for that
matter, where we were able to crash at least once because of
imperial/metrics confusion... ;-)

More likely Pop. The materials used are designed to take the weight and
are over rated.

Big mistake mixing units. I may think in imperial but work in metric
when I can.

Sad. I would like a bit of drama ;-)

smart. But then you grew up with imperial of course. I find it difficult
(not that I need it).

A similar incident happened on the platform I was on. Unfortunately the
crane driver was not so lucky. He got trapped in the cabin for hours and
lost a foot and part of his lower leg.

It is difficult and took years of repetition before it became second
nature. But after learning things like there are 5280 ft in a mile and
60 mph is 88 ft/s. Not to mention the currency. The metric system is a
walk in the park.
Also we oldies can add up in our head. Unlike the youth of today.

I just noticed a follow up video.
The cage the guys are in is galled a Billy Pugh and you are supposed to
stand on the outside so you don't get trapped if it goes into the sea. I
used them for my one trip on the Piper. A white knuckle job.
