This be t' second firin' o' t' USC Rocket Propulsion Lab's eight inch diameter, two grain solid rocket motor. Aye aye! It burns about 60 lb o' composite propellant in approximately 10.5 seconds. Avast, me proud beauty! T' average thrust be 1250 lb. Aye aye! This second firin' was a test o' a new steel nozzle design that proved t' be more robust than t' all graphite design from t' first firin' attempt. Well, blow me down! Video by Ian Whittinghill.
