Question

If the black box flight recorder is never damaged during crash,why is nt the whole airplane made out of stuff?

Answer 1

*drink*

Answer 2

DRINK

Answer 3

Yeah the weight, and aerodynamics, plus black boxes are sometimes destroyed in crashes. Also are you aware this is a Seinfield joke from like fifteen years ago?

Answer 4

i agree with the first poster

Answer 5

ALIUM IS LIGHT THAN METAL THE BLACK BOCK IS MADE OF SOMTHING STRONG TO HEAVY  LIFTH I HAVE TIME TO SAY TRY  THIS MAKE PLANE  WITH METAL (RULER MADE OF METAL)AND GLASS(RULER MADE OF GLASS)PLASTIC AND PAPER SEE WHICH FLY HIGHER

Answer 6

"Never damaged"?  You obviously haven't seen pictures of many.

Ok Moron:  We'll put you in an impregnable metal container and drop you so you'll land at the terminal speed of an armor piercing bomb.  Let's say it lands without so much as a dent.  You think you're going to live through the impact?

Answer 7

the airplane would be too heavy to stay in the air during a flight.

although the airplane being made out of the black box would be pretty sweet, its impossible

Answer 8

Weight and expenses.

Answer 9

Whoa. That's original!!!!!!!!!!!!

Answer 10

Your question is the biggest joke at Yahoo Answers.

If you type the words "airplane black box" into the area above that says "SEARCH FOR ANSWERS" you will see that that same question has been asked 180 times.

Answer 11

waaaaay to heavy the black box has like 5 inches of solid steel around it

Answer 12

Can we get permission to SHOOT the next MORON who asks this question?

Answer 13

They must get this question all the time at the National Transportation Safety Board.

Because the interstates aren't wide enough.

The point, in case you're new to sarcasm, 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. (Maybe THAT's how it got the name, "BLACK BOX")

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?

Answer 14

no such thing, the flight data recorders are orangeish -red-yellow

Answer 15

sometimes it is damaged during a crash. Plus, it's way to heavy and expensive to do such a thing. So it's risky and impossible.

Answer 16

the majority of the FDR and CVR are made of aluminum, same as the rest of the plane, the actual memory chips or tapes if its an old one is encased in a steel cylinder to be more crash worthy.

so the plane is made out of the FDR and CVR materials...steel and aluminum

Answer 17

Too much weight.  It would never leave the ground.

Answer 18

And sometimes even the black box IS damaged.
