What has this author upset are the bone-headed attitudes that are portrayed by the participants and onlookers: They seem to accept that these stage collapses are 'no big deal' or that they are somehow 'unforeseeable' or 'unpredictable' events.
After the Tulsa, Oklahoma windstorm that tore a video display frame from the upstage area and sent it crashing to the ground, Ivins, the Flaming Lips' bassist, said the video-screen collapse was unpreventable. "It was a freak thing that happened," he said, adding that the Lips are working on repairing the rolling video screen for their next festival gig, in Somerset, Wisconsin, in about two weeks. "Maybe the stage could've been facing a different direction. We could have tied the screen down, but it would probably have taken the whole stage down. We try to take as many precautions as we can, all the time. It's just sometimes there's stuff out of your control. You just never know what's going to happen." Really!? Dang, dood, why do you even get out of bed in the morning (or maybe afternoon) if you don't know what is going to happen. Yeah, life is unpredictable, but basic physics is VERY predictable.
These kinds of incidents (not accidents) ARE Predictable and Preventable. It's called engineering, review, and planning. We know weather happens. We know it is powerful. We know if something blows over or collapses and lands on someone it will very likely injure or kill them. What is so hard to understand about this!? With attitudes like those promulgated above, it is no wonder that more people don't get killed at concerts.
Demand more safety planning and review. This stuff doesn't just 'happen' -- it happens when you DON'T plan for it.
Here is a superb article by William Gorlin that was published in October 2008 that addresses many of the structural and operational considerations of temporary structures:
