Why cant a black box be destroyed?

A black box, typically an aircraft's flight recorder, is designed to withstand extreme conditions, including high impact forces, heat, and water pressure. Its robust construction includes a protective casing made of durable materials, ensuring that it remains intact even after a crash. While the data inside can be damaged, the physical device is engineered to survive in order to aid in accident investigations. This resilience is critical for improving aviation safety and understanding the causes of incidents.
