If the u-bolt connecting the cable to the head-ache ball is missing a nut and if there is a red-caution tape connected to the same thing. And if the oiler or the crane operator or the rigger is supposed to inspect this stuff each day before use. And if the Construction Manager spots this item and personally informs the Contractor's Boss. Then odds are pretty good that the crane is out of service until the nut is replaced. . .
Or just maybe it'll be used for a couple of more days to give Fate a really good chance to show up.
