Major Court Victory for Model and Amateur Rocketry

Are model rockers dangerous? According to a paper by M.T. Lynch, K.T. Bellian, R.F. Edlich and H.N. Himel (Model rocket engine burn injuries: the need for stricter regulation, Journal of Emergency Medicine12, 325-30 (1994)), during the 18-year period from 1975 to 1992, the US Consumer Product Safety Commission's National Electronic Injury Surveillance System database received reports of 18 burn injuries caused by model rocket engines.

That's only one injury per year, which isn't bad for a hobby as popular as model rocketry. Yet the authors of the paper cited above conclude, "The current regulations appear to be inadequate and need to be altered to cover the population at risk. Specific recommendations include imposing an adequate age limit and improving the labeling of these products."

Lynch and colleagues found an ally for their cause in the United States in the form of the Homeland Security Act and rules by the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE). The BATFE rules came to the attention of US Senator Mike Enzi (Wyoming), who in 2003 wrote pending legislation that will, "amend title 18, United States Code, to exempt certain rocket propellants from prohibitions under that title on explosive materials."

Senator Enzi stated, " "It's a sad state of affairs when we see a government agency and senators go to such lengths to squash efforts to preserve a constructive, educational and important hobby enjoyed by millions of Americans. This kind of opposition to my legislation serves to discourage innovation and darken spirits. It doesn't make Americans that much safer, but it does make us more fearful and less free."

While Sen. Enzi's bill languishes in the Senate, on 10 February 2006 the United States Court of Appeals for the District of Columbia Circuit issued its opinion as to whether the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) had properly classified APCP propellant as an explosive. As reported in a joint media release by the National Association of Rocketry (NAR) and Tripoli Rocketry Association, "the court found in favor of NAR and Tripoli and remanded the matter back to the agency."

Details about the decision are given on the NAR web site here and the Tripoli web site here.

Model rocketry enthusiasts have spent seven years in their battle with the BATFE. The court fully vindicated them and repudiated the government's position: "The problem in this case is that ATFE's explanation for its determination that APCP [ammonium perchlorate composite propellant] deflagrates lacks any coherence. We therefore owe no deference to ATFE's purported expertise because we cannot discern it. ATFE has neither laid out a concrete standard for classifying materials along the burn-deflagrate-detonate continuum, nor offered data specific to the burn speed of APCP when used for its ‘common or primary purpose.' On this record, the agency's decision cannot withstand judicial review." The full decision can be downloaded here.

On learning that NAR and Tripoli prevailed against the government in their suit, Senator Enzi issued a press release that stated, "People who build and launch model rockets for fun should not have to give up their hobby due to an unnecessary set of obstacles and an unjustified claim which classifies rocket propellant as an explosive. This safe, mind-expanding activity offers many benefits to today’s youth including increased interest in math, science, and space exploration while providing them with a fun recreational activity. While this decision is not the end, it gives rocketeers firmer footing and gets them closer to enjoying their hobby without having to bear the burden of unnecessary regulation. I hope the BATFE will see clear to give those law-abiding citizens the space they deserve and that in the end rocketeers will enjoy the same freedoms with their hobby as rock collectors and scrap-bookers enjoy with theirs.

The rocket launched immediately after this test launch carried a tracking light that in 1969 led directly to the founding of MITS Inc., the company that in 1975 introduced the Altair 8800 microcomputer on the cover of Popular Electronics magazine. Later in 1975, Paul Allen and Bill Gates began their collaboration with MITS that led directly to the formation of Microsoft. Photograph by Forrest M. Mims III.
