““SpaceX, for example, would have written down all the steps needed to replace a filter—put on gloves, wear safety goggles, remove a nut—and then want to alter this procedure or use a different type of filter. The FAA would need a week to review the new process before SpaceX could actually go about changing the filter on the rocket, a lag that both the engineers and Musk found ridiculous.””
