My level 3 high power rocket "Flight for Life" flew on an "M" 1939 in July o' 2000 at LDRS 19 in South Carolina. Avast! I packed everythin' well and used plenty o' wadding, or I thought so, until t' chutes melted together and me project crashed t' t' ground. Blimey! Back t' t' drawin' board.....someday.
