Demonstration o' usin' explosive bolts for t' separation o' solid rocket boosters (SRB) by Richard Dierkin' on high power rockets at t' December 2010 monthly meetin' o' t' Rocketry Organization o' California on Lucerne Valley Dry Lake, Mojave Desert, California. Aye aye! Unfortunately, I didn't get any video o' t' flight. It worked perfectly with all four boosters ignitin' as planned but also fallin' away together. Excellent job Richard.I know I'll be doin' this sometime soon.
