One of the commentators on the story says: "An empty plane flying every night – an excellent example of the value of spare capacity. But I wonder how many organisations would have taken a narrow view, classified this as “waste” and cancelled it?" is so on point. Reminds me of Tom DeMarco's Slack: Getting Past Burnout, Busywork, and the Myth of Total Efficiency ( http://amzn.to/1H4qRld http://amzn.to/1H4qRld ) which is all about having slack (spare capacity, which means not having 100% efficiency) in order to deal with unplanned issues. Failing to have slack results in a slow grinding process when issues arise and has enormous opportunity costs.
