The RRS provides a unique opportunity for the Southern California experimental rocketeer. It is a non-profit, experimental rocket organization composed of members sharing a common desire to supplement theoretical studies with actual rocket construction and launches. Safety has always been of paramount importance in the pursuit of these activities. The involvement of experienced members, as well as the guidance provided by the licensed pyrotechnic operators, has allowed the Society to conduct thousands of live fire tests since 1943 without a single accident resulting in injury. Research field trips are made to the MTA an average of 4 times per year for launches, static tests, and work parties.

The RRS is a society of amateur scientists sharing their interests, experience, and expertise. They volunteer their time and labor for the educational benefit of the Society and its members. As a result, members are free to begin any project of his or her choosing. There are no restrictions, but there are talented people of like interest who can help a project succeed. The thrill of a hot fire test has proven time and again to be one of the most powerful educational motivations imaginable. Failures encourage attempts to try again and successes generate the enthusiasm for new and more sophisticated projects.

Membership in the Society is open to anyone over 18 years old. Younger students can also participate in Society activities if they are sponsored by an adult member, parent, or guardian. Today’s Reaction Research Society is a vibrant, active, experimental amateur rocketry organization dedicated to the advancement of the aeronautical sciences and to the educational value of study in this field.

Rocket propulsion experimentation involves many potential hazards.  Personnel attending Reaction Research Society rocket activities will be in the proximity of hazardous chemicals, pyrotechnic devices, electrical equipment, tools, and machinery. The building and testing of such experimental rocket motors always presents some risk, however small, of fire, explosion, thermal or chemical burns, toxic poisoning, fragment impact, or electrical shock, just to name a few.  The danger associated with these activities is such that testing must be conducted at a remote location.  This limits access to the type of emergency medical assistance that would normally be available within city limits.  In addition, the time required for such assistance to arrive on scene might be considerably longer than normal, or an injured person might need to be transported to the nearest medical facility directly by others on scene.  Participants must also be aware that the actions of others attending these firings might result in an emergency situation causing injury to those in the immediate area.  While the Reaction Research Society has never had an accident resulting in injury to any participant in over 70 years of amateur rocket operations, participants attending RRS activities must be aware that the risk of injury or death does exist when engaged in rocket fabrication and test operations.
