WHAT MH370 BLACK BOX WILL TELL US - VIDEO

In science and engineering, a black box is a device, system or object which can be viewed in terms of its input, output and transfer characteristics without any knowledge of its internal workings. Its implementation is "opaque".

  A black box is a recording device used in transportation: the flight recorders (flight data recorder and cockpit voice recorder) in aircraft, the event recorder in railway locomotives, the event data recorder in automobiles, message case in ships, and other recording devices in various vehicles. Black box is a more humorous than accurate term. The recorders are generally not black in color, but usually bright orange as they are intended to be spotted and recovered after incidents.

The "Flight Recorder" was invented and patented by Professor James "Crash" Ryan from the University of Minnesota in 1953. The "Coding Apparatus for Flight Recorders was also invented by him. The Cockpit Sound Recorder was invented and patented by Edmund A. Boniface, Jr. of Lockheed Aircraft Corporation and originally filed with the U.S. Patent Office on February 2, 1961 as an "Aircraft Cockpit Sound Recorder". ( I saw all this on Discovery Channel and did my little research on Wikipedia *wink*)

The Cockpit Sound Recorder patented by Boniface provided a progressive erasing/recording loop (lasting 30 or more minutes) of all sounds (explosion, voice, and the noise of any aircraft structural components undergoing serious fracture and breakage) which could be overheard in the cockpit and was an analog device as described in the patent.

The MH370 "black box" search have been narrowed to a small radius on the Indian sea and anytime from now we hope it will be found and the mystery behind the crash will be unravelled. We will hear the recording of the last 30 minutes or thereabout of all sounds (explosion, voice, fractures and breakages) overheard from the planes' cockpit.  Angus Houston, the Australian head of search team and former chief of defense said  

“Let me now say that this is a vast area, an area that’s quite remote, and we’ll continue the surface search for a good deal more time. If we find a piece of wreckage on the surface … that gives us a much better datum to start the underwater search than we’ve currently got,”
