Air Command's Recovery Guide

Air Command has compiled an extensive guide to rocket recovery. Although oriented towards water rockets, it provides a comprehensive survey of processes and techniques. For example, we 'pyro' folks almost never plan to use lawn dart recovery (although we end up with our share of them). The guide does cover many things that are more common in our world than in water rocketry. What interests me most are the things rooted in water rocketry that I might someday want to try.
