Reisler) Organization: Hadron, Inc., Fairfax, VA Lines: 16 Keywords: SRB Destruct Mechanism Before the discussion gets totally out of hand, and not to shed doubt on the knowledge of our TV news personallities... From the February 10 Aviation Week and Space Technology article entitled "Solid Rocket Motor Designed with Conservative Margins" (page 53-57). On page 57... "The range-safety destruct system on the motors had to be used Jan. 28 when one of the boosters began flying back toward the Florida coast following explosion of the external tank and orbiter. That destruct system is a linear-shaped charge that runs down the side of the motor and when fired splits the moter open extinguishing combustion in the motors."
