Designed to survive The critical part of the black box is the crash-survivable memory and data storage. Earlier recorders used analog tape, but digital solid-state memory is used today. This is contained in a cylindrical housing engineered to survive extreme impact, heat, and pressure and protect the memory inside.
Why are black boxes kept in water?
Answer: If a flight data recorder is recovered from the water, it is submerged in fresh, clean water to prevent deposits such as salt or minerals from drying out within the device.
