Being as though we had to start developing our low-altitude balloon launches practically from scratch, we had to also create our own release pin that allows for the dropping of a payload and parachute deployment mid-flight. Thus, we bent, cut, and shaped a wire coat hanger into a sort of rudimentary cotter pin. After multiple tests and tinkering, we finally arrived at a functional release pin system. However, we are still designing multiple methods to release the payload so we can see which method is best to use.
