airplane question?????????

Question

if the black box is supposedly indestructable, why isnt the whole plane made out of the same thing

Answer 1

A 747 can carry over 300,000 pounds, which could be swapped for extra tough construction, but the real reason is this:
If the aircraft was indestructable, if you hit something at all, it would exert forces on the people equivalent to hitting a brick wall at the speed they are moving, so they would pretty much splatter all over inside.
If the aircraft is made so that it can break apart, if you make an emergency landing you can sacrifice the wings and landing gear to save the people.
During my private pilot training, they trained me to use the plane to save the passengers. If you land in trees, dont let the body hit a tree, let the wings take the hit.
If you have a choice between a clear small field or a big field with vegetation, use the vegetation as a cushion, but dont use the short field because after you touch down, you're going to smash into whatever is at the end of the field and die.
If you have a choice between a rough field and treetops, you can land on the trees and be suspended by the canopy, but the rough field is likely to make the plane cartwheel and explode into a bunch of chunks and kill the people.
An indestructible plane would just burry itself in the ground and kill all the passengers.

I had a feeling bostonianinmo would answer the same thing

Answer 2

It's not indestructible. It's protected mainly by the crushable cabin of the aircraft. Only the data recorder mechanism is hardened. If you built an aircraft to those standards, it would never leave the ground. Imagine an M1A Abrams tank with 3 foot wings.

Even if you had some magic material that was totally indestructible and light enough, the passengers would still all be killed. When the aircraft crashed, it would come to an instant stop but the passengers would keep moving at 500 MPH. They'd but cut in half by the seat belts which would act like cheese slicers. The body parts would then be smashed into the seat or bulkhead in front of them and all of the guts and goo would spray all over the inside of the aircraft. Nice visual, eh?

Answer 3

Besides the integrity of the airplane, you have to consider the passengers inside. Supposedly, a black box can survive a fall from dizzying heights. The hard drives (magnetic recorders) are protected within. However, I fear the humans will not be able to withstand those deceleration forces and will become splattered on the floor of the plane. They are built to withstand over 3,400 G's, an amazing force!
That's not the mention the the plane would never get off the ground because it is so heavy.

Answer 4

This is awesome!!!

Answer 5

Way too expensive. Also they are very heavy so if the whole plane was made of that metal it woulds require much more powerful engines and then the prices of the tickets would skyrocket.

Answer 6

have you ever seen or hled a black box??? they are VERY heavy! if a whole plane was made of one, it wouldnt even get off the ground.

Answer 7

to heavy to fly.but even if it was made of that material,slamming nose down into the ground only going to make you go mach six into the seat in front of you,or the seat belts going to cut you in two.

Answer 8

Good question. Guess people's lives aren't as important as that info.

Answer 9

I think a lot of people have asked this quesion before. I wonder that, too!

Answer 10

Cause it would be to heavy to fly.
