There's a mine in Australia called "The Flying Windlass Mine".

Old Tom (as he told me the story personally) had done quite a lot of blasting in the military using 'real stuff' - even had his powder monkey's ticket. In this mine they struck a big boulder in the shaft - so they asked him to 'knock it loose'. He rang up the local (outback) Sargent at the Police Station - as was the wont just to let him know where and when to expect big noises as a public service, and asked his advice on using fertiliser/diesel ...

Tome thought when the Sarge said - oh it's about "X to 1", he meant that it was about that amount less powerful, so just to be sure, he put at least X times as much (and a little bit just more to be safe! - no point in doing a job twice, when you can do it properly the first time!) as he would have used of what he normally used...

Anyway to cut a long story short...

He didn't just 'nudge it loose and chop it up a bit'... they watched this volcano of rubble spew skywards... then realised "what goes up..." and dived under the old Holden ute...

Of course, the windlass that used to be at the top of the shaft...

Hence the new name ... there's probably a song in there somewhere...
