> and on the second test, the engine exploded on the pad Wow, was this a standard ESTES engine? Never heard of that happening before. Just curious, what would you say the blast radius was (ie: how close could I have been without getting hurt). I ask because I always have to argue with people to stay well clear of my model launches and they laugh when they see/hear the little pfffffffft of the engine.
