Titled:   Rocketry Hobbyists versus the BATFE

The DC Circuit Court of Appeals has handed down a stinger of a decision against the BATFE and in favor of small children, science teachers and boys of all ages. Yes, ever since someone woke up in a bad mood and decided to classify model rocket engines as explosives, this hobby has faced increased regulations and costs. The judges had this to say (emphasis mine):

"The problem in this case is that ATFE's explanation for its determination that APCP 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."

It's a pity it wasn't in reference to "sporting purposes" or the current rules regarding US content of imported firearms, but it's a start in the right direction.
