I launched this 1/2 scale Patriot missile at High Frontier 8 in Pawhuska, Oklahoma on September 24, 2011. This launch was hosted by Tulsa Rocketry. I successfully got my Level 3 Certification from Tripoli Rocketry Association. The altitude was 4,808 feet on an Aerotech M1297. The rocket weighed 41.06 pounds on the pad. The thrust to weight ratio was 7.17/1.
