Minimize cargo damage: The supply pods must be designed so they protect the supplies inside when the pod collides with the ground. Damaged supplies will not help the people who need them. Maximize shell condition: The shell of the pod should be reusable after the drop. If the supply pod has almost no damage, the whole outer shell may be used as a temporary shelter for up to three people, protecting them from the sun and rain. If the supply pod is slightly damaged, pieces of the shell can be reused as building materials. If the pod is severely damaged, the shell cannot be reused. Keep costs low: The cost of the pod must be low so International Disaster Aid can help as many people as possible. The lower the cost of each pod, the more pods International Disaster Aid can build and deliver. What are the 3 criterias required for this project
