Perhaps, though this is probably hard given airports, take off slots and such. Sometimes the backup plan is occasional failure. Resiliency is expensive. We don't tend to own up to our decisions when we (companies, individuals, etc.) opt to pay for for limited resilience. But besides our irrational denials, it's often a rational trade off. Take the recent FB downtime for example. FB's bigness means that FB downtime had some significance but FB is not critical infrastructure. Thousands of decisions, trade offs and compromises reflect that. If there's trade off between costs or speed of software development and resilience... FB will/should not always choose resilience. That's rational. Being stranded for a day because airlines is something that happens n% of the time. Cost of the mode.
