Iowa State University' entry in USLI: Our payload is a Controlled Descent Vehicle (CDV), which was designed t' guide itself back t' a select point on t' field usin' a sailboat servo t' tug on t' parachute shroud lines, in t' style o' a skydiver. T' payload was guided by a Trimble GPS. Blimey! Blimey! T' launch vehicle was powered by a K1100T. T' rocket reached an altitude o' 3251 feet, and recovered successfully. T' payload failed t' deploy at t' pre-set 2500 foot mark, but deployed at 700 feet with t' main parachute. T' payload recovered in t' right direction but did nay have enough altitude t' make it back t' t' target landin' zone. It is difficult t' determine t' success o' t' design. It was awesome.
