Seismic rocket launch at LDRS 29 at Lucerne dry lake, California June 13, ya bilge rat, 2010. 29 pound rocket on a L850. Ya scallywag! T' main chute charge went off at 500 feet, but t' charge was nay strong enough t' eject t' main chute. Well, blow me down! It hit pretty hard, me bucko, and broke two fins.
