Minneapolis Metrodome Roof Collapse

Minnesota Star Tribune 12/12/10: The Metrodome roof collapsed early Sunday morning and the Vikings-Giants game that had been rescheduled for Monday night at the Dome will be played in Detroit instead. The 9.5-acre Metrodome roof tore in three places shortly after 5 a.m., said Roy Terwilliger, head of the Metropolitan Sports Facilities Commission. Aerial photos show the roof tore in two places in the center and one near the edge of the roof.
(Roy Terwilliger, head of the Metropolitan Sports Facilities Commission.) said normal procedures were being followed Saturday, with workers on the roof itself using steam and hot water to melt and remove snow. Also, the heat inside the Dome was turned up and hot air was pumped into the in-between layers.

"That didn't work," Terwilliger said.

"Then it got dangerous for personnel up on the roof and we decided for the sake of safety to take them off," he said.

Man, if this was the 'longer version' that ant pointed to above (which it looks like) then it would seem no one has a nice, long version of this that keeps going. Why did it stop so abruptly?

Well it's not exactly a long event, a few of the sections gave way and some snow fell in, it's not like the entire stadium collapsed. I'm guessing it's not longer because this is probably about what there was to show.

Naw that is everything to the event. The roof and scoreboard don't come all the way down because of massive cables that crisscross through like a giant quilt. Surprisingly the fix is real easy. Get a couple new panels, needle and thread, and turn on the giant air compressor (not kidding) and that is it.

BTW Notice all the air blowing out on the close-up shot of the hole. I wonder how fast that air was blowing through, considering it requires 250,000 ft³/min (120 m³/s) of air to maintain inflation.
