[...] it went Thursday at an Independence Day festival in Utah, where officials said a pig-shaped hot-air balloon descended quickly to the ground after hitting a Wyoming cowboy-themed entry. The collision ripped a hole in the nylon fabric of the pig balloon, and a piece of plastic caught fire as it descended. The pilot, Erwin Oertli was the only person in the balloon and suffered minor burns from melted plastic that dripped onto his face, the bank said in a statement. Witness Kevin Auernig, 37, of Provo said he saw the accident at America's Freedom Festival Balloon Fest and watched the pig balloon come down fast and land in a fenced construction zone.
