The construction of the Digital Flight Data Recorder and Cockpit Voice Recorder boxes is military grade. And they are virtually indestructible.
But there have been many cases where the impact was so strong that even the black box couldn’t sustained damage. Still, why not built an airplane using the ‘strengthening’ concept, isn’t the stronger the better.?
NO ! since as its well known that, its not the fall that kills you, its the sudden stop.
An indestructible aircraft may survive that sudden stop but no human could.
Black boxes are placed in protected locations near the rear of the airplane and, unlike humans, they are designed to survive accelerations up to several hundred g-forces.
Passengers don’t die because the plane is not strong enough.
Passengers die because unlike black boxes, passengers’ bodies are not strong enough to survive the rapid deceleration, smoke and fire that ensue in a crash.
Along with carry-on bags, laptops, food trolleys etc some of which may hit you while traveling at speeds of several hundreds of kmph relative to your body.
Hence the best way of protecting airplane passengers is to avoid crashes in the first place. Task at which our technicians and engineers are getting better each day passing.
It is remarkable how the number of aircraft accident fatalities has not significantly increased in the past 50-60 years despite the fact that air-traffic has increased by a factor of a significant margin !
