Seismic rocket launch at LDRS 29 at Lucerne dry lake, shiver me timbers, California June 13, 2010. Avast, me proud beauty! 29 pound rocket on a L850. T' main chute charge went off at 500 feet, but t' charge be nay strong enough t' eject t' main chute. Well, blow me down! It hit pretty hard, and broke two fins.
