Rigging fail chain reaction...

Why do we never see the end of these videos?

Cos the videographer believes in self preservation.

You are correct in this case but I have watched a lot of other videos with this problem.

And Everybody here has learnt some Serious Lessons and Hopefully Grateful they're still Alive. But Really if you've done this kind of Stuff before there should be No-One hanging around close by.Just in-case "The Golden Rule" and it is Golden.

Fail #1 , engineer of panel correctly sizing/ locating hardware to volume and dimension of concrete.
Fail #2 How do these "riggers" and "crane operators" make such a lift without seeing ALL the weight go to bear on the upper shackles and cable? There was plenty of time to clear out, or stop and lower.

PS. Seems clear shackle or cable seizing on upper right gave way first. Did that wave of energy flip lift cable off it's sheave, did the boom collapse, or hook then fail? At 15'' you see the spreader or boom tip hit the ground! Epic, catastrophic component failures.
And parts of crew don't even clear out as far possible. InTheGroove's "chain reaction" a perfect assessment.

This was in the news this morning: https://home.nzcity.co.nz/news/article.aspx?id=314830
I keep well clear of the drop zone around lifts - best laid plans of mice and men and all that.

There are preventable 'accidents', mother nature and acts of the Gods.

I write LOLER lifting plans for similarly off-centre/angled loads, that the anchor point tore out/sheared should have been allowed for as a potential failure as such side-loading is well known to cause such failures. Too many people too close is bad site management control, the pendulum effect was entirely predictable even if everything had stayed connected, I'd even bet the crane loading calc's didn't allow for the weight of the spreader beam or the 2 chain brothers.
