Seismic rocket launch at LDRS 29 at Lucerne dry lake, arrr, California June 13, 2010. Avast, me proud beauty! 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. Blimey! It hit pretty hard, and broke two fins.
