Rewiring in an "empty" and a plea for your spare Wagos

Cables are fine guv, you didn't didn't tell us it was in metric/imperial

I can't now remember exactly what it was but even fairly recently there was some massive space related cockup and upon investigation it turned out that half the American engineers has calculated using imperial, the other half metric and no-one had realised

That was the Hubble telescope.

The Hubble mirror was out be a tiny amount, so it had a monocle fitted.

Hubble's Mirror Flaw - NASA Science

Launched on April 24, 1990, NASA’s flagship Great Observatory has far surpassed its original mission goals. Hubble has more than doubled its 15-year life expectancy and significantly expanded our understanding of the universe while simultaneously unveiling new mysteries that prompt further...

The big screw up with imperial/metric was the reason the Mars Climate Orbiter was lost:

So what units do these Yanks actually work in? I know it's inches, but is it inches, 1/10, 1/100, 1/1000 etc., which is effectively the metric system, but with a different reference length, or do they actually use yards, feet, inches, 1/4, 1/8, etc.
If it's the latter, it's no wonder mistakes occur.

Someone is going to be looking for a new job... What I find funny is the notion of two blokes pulling in the cables and find the first one is two short.. One guy turns to the other and says "I think this is too short", other bloke says "Meh, not my job" and they carry on installing the other 899 cables regardless...

Nobody wants too much left over but always best to be too long than too short..

Any Americans I've known have quoted measurements in the latter form.

Cheeky fxxxxx! Fair point though!

My 37m error cost me £196 which I took on the chin. Imagine what these guys are out of pocket by!

I think 'these guys' are us taxpayers as I believe that yard was bought by the Scottish government.

 

[SparkySy]

Sounds about right taxpayers bailing out another f@@k up!
where is the slaps face emoji when you need it!
