Members of the Michiana Rocketry prep a 10-foot, 450 pound porta-potty, mounted on rocket motors for launching, Saturday, December 6, 2014, from a field in Three Oaks, Mich. It made an arc and almost landed on a spectator’s pickup truck, 2,000 feet away. A group of Michiana Rocketry club members planned the project for more than two years. The club is trying to increase awareness of rocketry as a hobby and prove it’s possible to turn a porta-potty into a rocket and launch it successfully. About 30 people worked on the rocket, from engineers to sales people who lined up sponsors. (Photo by Don Campbell/AP Photo/The Herald-Palladium)
