Cutaways are a strange thing... we don't want to have them, but we also want to know all about them so we feel prepared if and when we ever have one. One way to prepare is to do an intentional cutaway on a system with a tertiary reserve like the one in this video, which shows all sorts of different malfunctions. Hey, I figure if we can't actually have all these mals to prepare for, at least we can watch them on video and see them handled well. Good stuff. We got this.
