DART San Diego Model Rocketry Club. Launch o' a hybrid discontinued Estes #1284 Space Shuttle with Stack. Well, blow me down! Blimey! Powered flight achieved utilizin' a D12-3 Engine. Avast! Blimey! Note that t' Orbiter stays with t' Stack until t' moment o' t' firin' o' t' ejection charge. Blimey! Blimey! Why do you think that this occurs?
