were the black boxes of the planes involved in the 9/11 attack ever retrieved?

Question

what did the recordings on the black boxes of the airplanes say?were the black boxes ever found?in most airplane crashes if not all the media always mentions that little black box.however,this time there was only mention of cell phone calls.did they just bury the plane wreckage at the world trade with the black box there?au povoir.

Answer 1

Yes for Flight 93, Pentagon, and one of the planes that hit the WTC.

The conspiracy theories are all a bunch of crap; Popular Mechanics/Science has some simple explanations. Go You Tube "loose change/popular mechanics", and watch their debate. There isn't much of a debate. ;)

And.. If they made planes out of the types of materials that they make black boxes out of, then planes would not fly. Planes are made out of light materials, light materials don't have enough mass to absorb and disperse the types of energies associated with hitting the ground at 600 MPH. If you were able to construct a plane that could, the human body would not be able to withstand the associated trauma of decelerating that quickly. Imagine your internal organs hitting the front of your rib cage at 600 MPH.

Answer 2

No word of the "black boxes" from those planes were ever mentioned in the press. The tired joke about how planes should be made out of the same stuff is so lame. That piece of equipment is made of heavy sheet steel. If the plane were made of that is wouldn't be able to get off the ground and even if it could that would not make it crash proof.

Answer 3

no person, different than diehard professional conspiracy theory supporters, have self assurance that the homes weren't demolished. there is not lots room for argument as purely employing the undisputed regulations of physics provides you with that end. Paul Craig Roberts, the so called father of Reaganomics, and not some loopy Liberal conspiracy nut, sums it up succinctly: "i'm going to start via stating what all of us comprehend to be a superb incontrovertible scientific actuality. all of us comprehend that it extremely is precisely impossible for any construction, much less metallic columned homes, to “pancake” at loose fall velocity. consequently, it extremely is a non-arguable actuality that the professional clarification of the cave in of the WTC homes is fake... because of the fact the damning undeniable actuality has not been investigated, hypothesis and “conspiracy theories” have crammed the void." I assume you already comprehend proper to the black field question, so i'm going to spare you the main factors.

Answer 4

Black boxes are not indestructible, it only takes about 1 million psi to liquify any metal instantly, and the plane hit with about 6 million psi.
When the buildings fell, they put over 20,000,000 psi on some of the columns, leading to large amounts of liquefied metal in the center of the rubble.
Oh, and they dont make planes out of black box material because the people would just splatter all over inside the plane if it hit anything.
We (Pilots) are trained to sacrifice the wings and landing gear in order to decelerate the aircraft safely, and obviously try and avoid destroying the fuselage.

Answer 5

cue the great conspiracy theories! But in all honesty I'm not sure I don't remember hearing much about them. They should build the planes out of the same material though seen as though the black boxes on planes seem to be almost indestructable, would save a lot of lives in the aviation industry.

Answer 6

yes they were retrieved it seems that the terrorist threatened the captain to turn of the transponder before hitting wtc
the transponder is the devicethat shows the position of the airplane to the radar at the conrol room
