Re: That's some 'gully'
"Also; if they know where the truck was bogged, why would it be hard to find the break?"
As stated in the article, it's very likely that the cable will be broken is several place due to the tension put on it as the truck was dragged out - the only way to find the breaks is to use an OTDR (Optical Time Domain Reflectometry) to locate the nearest break to the cable end, fix that, test, locate the next break, fix that, rinse and repeat as necessary.
These breaks can be hundreds of metres away from where the truck was bogged.
