Why did aviation safety regulations drive the standardization of survival kits?

To ensure passenger survival in remote areas after crashes

As commercial and military aviation expanded during the mid-20th century, the risk of crashes in remote, isolated environments—such as dense jungles, deserts, or open oceans—became a significant concern. Regulatory bodies mandated that aircraft carry specific, compact, and lightweight survival gear to support passengers for a minimum duration while waiting for rescue. This move transformed the survival kit from an optional item into a required piece of safety equipment, ensuring that standardized, purpose-built gear was always available when infrastructure failed.
