The crew of Apollo 13 is stuck in orbit around the moon and the NASA crew on the ground is trying to figure out how to get the astronauts home alive. Faced with only the tools in space and a limited time window, the engineers must use every available item at their disposal to maximize the amount of time before reentry to Earth’s atmosphere. This clip is a nice introduction to the idea of consumer choice, budget constraints, and utility maximization. All resources must be used in the model and there is no value to saving anything. The goal is to earn as much utility as possible given the budget constraint. The same issue faced the NASA engineers: they had to use all available resources, there was no benefit to saving items for next time, and they had to maximize the time/oxygen/energy for the astronauts.
