anyone else hear or see this on the news over at Yanky Land?
The roof of the Metrodome stadium in Minneapolis collapsed early Sunday morning after a blizzard dumped 17 inches of snow. Because of the damage to the stadium, Monday's scheduled New York Giants-Minnesota Vikings game was moved to Detroit's Ford Field
Cameras were positioned inside the stadium and caught the collapse on tape. To call the video incredible would be an understatement. It looks like the beginning of Armageddon:
Yeah, you would think that in Minneapolis of all places they would make the roof strong enough to withstand a lot of snow. What a bunch of maroons! Now they have to play their game right here in the Motor City, where people know how to design roofs.
Actually the roof is a rather nifty piece of engineering - 10 acres of 1/16th inch Teflon-coated woven fiberglass panels held up by 20 90-horsepower fans. It weighs 580,000 pounds and has deflated twice before since being installed in 1981. It's really more like a big flat balloon sitting on top of the stadium. Note that the news accounts say the stadium itself suffered no structural damage. http://www.msfc.com/about.cfm
Forty-eight days after the Dome was inflated, a major storm dumped more than 10 inches of heavy wet snow on the Dome. The weight of the snow caused the roof to partially deflate. A rip in the roof was caused when a bolt snapped, leaving a sharp piece of steel to tear through the fabric. Air escaped through the tear and the Dome deflated. The rip was repaired and the Dome was re-inflated within four days. The fabric roof has torn a few times since then, but it has only postponed an event or game once - in April of 1983, a baseball game between the Minnesota Twins and California.
Two rips within its first 2 years doesn't sound like such nifty engineering to me.
