==Precautions and safety==
Model rocketry is a safe and widespread hobby. Individuals such as [[G. Harry Stine]] and [[Vernon Estes]] helped to ensure this by developing and publishing the NAR Model Rocket Safety Codes<ref name="autogenerated1"/><ref>[http://nar.org/NARrcrbgsc.html Radio Control Rocket Glider Safety Code] {{webarchive|url=https://web.archive.org/web/20061210084116/http://www.nar.org/NARrcrbgsc.html |date=2006-12-10 }}</ref><ref>[http://nar.org/NARhpsc.html High-Power Rocket Safety Code] {{webarchive|url=https://web.archive.org/web/20061205044939/http://nar.org/NARhpsc.html |date=2006-12-05 }}</ref> and by commercially producing safe, professionally designed and manufactured model rocket motors. The safety code is a list of guidelines and is only mandatory for National Association of Rocketry members.

A primary motivation for the development of the hobby in the 1950s and 1960s was to enable young people to make flying rocket models without having to construct the dangerous motor units or directly handle [[explosive]] [[propellant]]s.

The NAR and the TRA successfully sued the US [[Bureau of Alcohol, Tobacco, Firearms and Explosives]](BATFE) over the classification of [[Ammonium Perchlorate Composite Propellant]] (APCP), the most commonly used propellant in high-power rocket motors, as an explosive. The March 13, 2009 decision by DC District court judge [[Reggie Walton]] removed APCP from the list of regulated explosives, essentially eliminating BATFE regulation of hobby rocketry.<ref>{{cite web
