The Collapse of the Minneapolis Metrodome

I originally found this video over at i09 and couldn’t resist sharing it.

Apparently the dome, an “air-supported membrane structure”, has deflated before. According to the official Hubert H. Humphry Metrodome website, the roof is made of 10 acres of teflon-coated fiberglass 1/16″ thick. Alternatively, if you’d like, that is 580,000-pounds of fabric or 800,000 square feet of fabric.

Something around 17 inches of snow sufficed to puncture multiple holes through the canopy, subsequently collapsing the top of the structure,  causing some serious destruction of the stadium and some amazing footage in the process.
