Why can't they make a plane out of the stuff the little black box is made of that never gets destroyed?
Answers:
ask Jerry Seinfeld.
Because it wouldn't fly - too heavy, no aerodynamics, no engines (shall I continue?)
it would be too expensive
First off the black box is not indestructable.
Second its not black.
Third when a plane crashes it not the plane being destroyed that kills you, but the sudden impact with the ground.
Interesting notion. I never thought of that. Maybe the price of the material deters us from making a plane using that material, or maybe if planes were made indestructible, terrorists couldn't kill massive number of people in a dramatic way, and then power hungry goverments couldn't strike in retaliation in order to acrue more wealth.
Because it's tiny and it can be built reinforced. Everyone would still die if the plane fell out of the sky and didn't break apart. You wouldn't survive that kind of impact anyway!
They must get this question all the time at the National Transportation Safety Board. The guy I talked to didn't miss a beat with the answer: because the interstates aren't wide enough. His point, was that a plane built to black box standards would be so heavy you'd have to drive it rather than fly.
Unlike the rest of the aircraft, which is mostly made of light materials such as aluminum and plastic, the cockpit voice recorder and the flight data recorder are encased in stainless steel boxes roughly 10 inches by 10 inches by 5. The steel is maybe a quarter inch thick and the boxes are so heavy in consequence that the designers don't even bother enclosing the accompanying electronics, which in a crash generally meet the same fate as the passengers. As an added precaution, the boxes are lined with a liquid-filled foam bladder encased in plastic that's supposed to protect against the intense heat of a post-crash fire.
Over the years these precautions have proven pretty effective. Investigators got useful data off one recorder that had been immersed in the ocean for seven years. But in another crash in Thailand the recorder landed in a pool of flaming fuel and basically got cooked.
One thing the NTSB learned from experience: be careful where you put these things. Recorders used to be located near the point where the wings joined the fuselage, the theory being that this was the most heavily constructed part of the plane. Problem was, being heavily constructed, the parts of the plane falling on the recorders often crushed them. Now the recorders are put in the tail section so that, assuming your typical crashing plane goes in nose first, the forward part of the airframe absorbs most of the impact.
Sitting back there won't help you, though. When you mix stuff in the Cuisinart, you think it matters which end of the banana went in last?

Apart from the fact that the box is orange (!), it is made of an aluminium housing, surrounding a high-temperature insulation of dry-silica material that is 1" thick. Then there is a stainless steel shell about 1/4" thick - titanium os also used. Oh, and another reason they survive is where they are located on the plane.
They are very heavy and very expensive. If the plane were made of the same material, they would never take off!
I've always wondered that
I would pick Tansy for the best answer it cleared things up
too expesive and it wouldnt fly
the wee black box is idigo orange and the plain would be too heavy to get of the ground if it was made of the same material. its called the black box after a psychologists theory of cognitive proccesses ie information the brain takes in , skinner or piaget i think
