Launch site in Orangeburg, SC by a model rocket club that meets on a 1-mile diameter sod farm. These guys are SERIOUS about their rockets and this 450-lb super-size model was the prize of the day. It had two M-class engines and a single experimental O-class engine, too. Unfortunately, the two M-class engines failed on launch. Note one shoots off to the side and one falls out in mid-flight. Still spectacular in my book!!!
