why can't they make the whole plane out the material that made out of little indestructible black box ..??

Then we shd paint the whole plane outto Black colour...which makes plane to attracts more sunlight which makes planes to genrate more heat and becos of it the passengers would burn in the filght before they get down...!!!

If the unmovable object is not unbreakable, it WILL be broken. \nI believe this is an unanswerable question.

They already have it! It is called a Grid Square MRE Bomb! It is freaking awesome! Ithink there is actual footage of it on the internet!

Actually it's not that simple. It is carbon fiber in majority, but usually this is used along with metal structures like honeycomb aluminium. Carbon fiber is used on its own on parts that have to be delicately shaped, like, for example, the wings.\nThe pieces are moulded together by hand, after being cut using templates, then are heat-treated in an autoclave, which is like a giant oven. That hardens the carbon fiber structures and gives them 7 times the strength of aluminium. That's why honeycomb metal is used in crumple zones (areas of the car that are designed to break up in crashes), like the sidepods or the nose cone.

It's a pretty simple project. It's a car about the size of a matchbox car. But it's made out of lighter materials like wood or plastic. With a holes bored through the center in the shape of an "L" When the balloon is filled with air and released, the car moves forward by jet power from the escaping air. \n\nBasic directions: make or buy a small matchbox sized car made from plastic or wood. You can either drill two holes to form an "L" shaped passageway in the center of the car, or you can hollow out the car and glue small tubes inside it to make the "L" shaped passageway. Of course, you'll also have to put a small chimney with a lip on the top of the car; this holds the balloon in place. So, the balloon sits on top of the car. The jet exhaust points out the back.  Blow into the exhaust hole on the back of the car to blow up the balloon. Put your finger over the hole to keep the air in. Set car on the floor and release. As long as there are no leaks and the car's wheels spin freely, it should work fine. The lighter the car the faster it will go. The bigger the car, the more stable it will be. \n\nYou can try getting a pinewood derby kit from the local cub scout's supply store. However, you should replace the pine body with balsa wood. It's lighter. \nGood luck.

Although it is possible, It would take a lot of effort and materials to do this. There is also the chance the rocket could fail and could even explode in midair, and I don't think we want to see that.\n\nThere could be a better but similar plan though.

they are keeping it a secret, cos they don't want the world to know that n.a.t.o aircraft are not as invinceable as they make them selves out to be?here i'll give you the link

Airplane flat out without it we wouldnt have the need for Sporks. I have a few other inventions that I think are pretty much in the running though. consider false teeth, the straw, and paper clips.

You don't !!!   Don't be silly, you could really hurt yourself or others trying to make it.\n\nAnd, just why would you be wanting to make this any way ???

Its mostly because of aerodynamics.With the Present propulsion method we cannot device those aircraft.Primarily circular aircraft shud rely on air for lift and it cannot take off as easy as normal one used now.\nMoreover Manoeverability cannot be achieved to the max with present technologies.\nBut who know it might be real one day..we cud have them.

Attach a falcon to the prototype.. Think it will fly high! :-)

Ah, the Spruce Goose was the largest airPLANE ever built. More on that  story below. This person asked about the largest airCRAFT ever built, which would be a dirigible.  "Ended in disaster" must mean the Hindenberg!  I am not sure if the Hindenberg was the absolute largest dirigible, but it certainly was one of the largest. The Hindenberg burst into flames upon docking in New Jersey someplace in the 30's and pretty much ended the Dirigible business. That incident is where we get the phrase "Oh, the humanity!"  which is often mocked, in my opinion inappropriately. That is an interesting whole story itself but is off topic.\n\n\nThe Spruce Goose: During WWII, metals were in short supply;  all those battleships and overseas ore shipping routes inaccessible, I suppose. So, Howard Hughes' aircraft company was encouraged by the government to try and build aircraft from alternative materials.  Wood is light and strong, so it was a natural thought.\n\nProblem is, one piece of wood can have a very different density and even strength than another. Doing the structural analysis on such a craft and keeping it balanced is an absolute NIGHTMARE.  I don't know if the spruce goose itself ever flew but it was a prototype and the conclusion of this engineering study was that this wood idea was impractical for large aircraft. \n\nNo doubt you can find more details on The Hindenberg, The Spruce Goose and "Oh, the Humanity!" in wikipedia.\n\n(This is not quite an Astronomy question.)

I'm pretty sure they have oxygen tanks on board or they might have an intake valve somewhere outside the plane for the few oxygen atoms floating around up there but the oxygen already in the cabin from take-off should be enough for the flight itself.

I suppose we could find some sort of clear plexi-glass type of material that would be suitable for aircraft-grade structures, but making the entire plane clear would probably be impossible.  A materials science engineer would probably know more about this.\n\nOne question from me though: is there a need for this?  The stealth bomber, for example, flies so high that visual detection by ground based anti-aircraft emplacements is quite low.  So low, in fact, that I have heard that it has never been fired upon from the ground (don't quote me on that though).  So for modern military aircraft applications, I would say radar invisibility is far more important than visual invisibility.\n\nAs a side note, I had read about a clothing-like light scattering material in either Popular Science or the Spectum magazine (forget which).  Anyway, it somehow bends or scatters light in such a way as to partially reveal what is behind the covered object.  There was a picture of a guy wearing a piece of it, and I was pretty amazed.  It was far from perfect (could still obviously see the guy), but I could imagine it being a very useful camo material if it improves.

electrons can't line up in a plane they wouldn't all fit... unless it was like a big 747... or one of those military airbus things... and by 3d do you mean 2 spacial dimentions + time or 3 spacial dimensions? cause we already live with 3 spacial dmension (4 including time)

airplanes use the CG every time it gets on the runway.  Maybe something along those lines.  THere are a lot of info on it if you do google on it.

Ive seen them used before too but the efficiency and force they produce falls way short of compressed air.  Making an air canon would be your best bet and its probably safer.  It would definitely be easier to construct.
