Few people know it but FSI had a big fire in summer of 1980. Wont go in to the details but a guy working nights , NOT ME, got a hot tool into the propellant of a Mach 1 thruster and it went off. Had a pretty serious fire and Lonnie and Larry were really wondering if they were going to call it quits. I helped clean up for the rest of the summer and went to work at another job. In this time is when they decided to press on and moved production to Lone Jack, Mo. Shipping was always out of Raytown. After basicly the family moved the equipment to Lone Jack is when I started working again for them. Leo that motor you have is probably ok but i would worry more about the age as if the grain has been cracked over 26 yrs.
