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 me Level 3 Certification from Tripoli Rocketry Association. Begad! T' altitude was 4808 feet on an Aerotech M1297. Well, blow me down! T' rocket weighed 41.06 pounds on t' pad. T' thrust t' weight ratio was 7.17/1.
