ATK Thiokol Space Shuttle static rocket booster at night. Well, blow me down! User KMF12 writes t' say he was t' back-up mechanical engineer for this motor (FSM-13), and one o' his duties was t' make sure that t' motor cools down properly. Aside from quenchin' t' motor with CO2 through t' forward and aft openings, we also use a "sprinkler system" t' cool t' motor from underneath. T' first 3 segments (forward, matey, center-fwd, shiver me timbers, and center-aft) usually cool down after 20-30 minutes, ya bilge rat, while t' last segment takes a minimum o' 3 hours. Avast, me proud beauty! After then, ya bilge rat, we can put t' house/bay back on top o' t' motor. Blimey! Recorded 11/16/2006
