Damn...I'm glad you're ok, but I'm sad about the bad news(obviously)...when something that bad happens in a place where people is just supposed to have fun and be happy it's even worse.
Sounds pretty much like what happened a couple years ago here in italy, no big tents involved but the 6 HUGE metal constuctions for the speakers collapsed during a 30 minutes windstorm at the biggest summer festival we have...30 injured, no deads just out of pure luck because people started searching for shelter under the big tents and other construction seconds before the towers went down...
