Dragline Boom Collapse

I'm not sure what caused this boom failure, but it looks like it might have been a tightline failure. This is where the bucket comes too close to the boom, either damaging the boom directly, or by folding the boom in half through the combined stress coming through the tight drag and hoist ropes.
