Clark Lindsey has some good news on the model rocketry front–a legal victory over ATFE (a situation about which I’ve written previously). I love this quote from the ruling judge:

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.
