> How indestructible are the so-called "Black Boxes"? Each airplane is
> equipped with a Flight Data Recorder and a Cockpit Voice Recorded. The term
> "Black Box" is used for these pieces of equipment.
> The National Transportation Safety Board (NTSB) web site gives valuable
> information regarding these devices. Regarding the Cockpit Voice Recorder it
> says:
> "The CVR records the flight crew's voices, as well as other sounds inside
> the cockpit. The recorder's "cockpit area microphone" is usually located on
> the overhead instrument panel between the two pilots. Sounds of interest to
> an investigator could be engine noise, stall warnings, landing gear
> extension and retraction, and other clicks and pops. From these sounds,
> parameters such as engine rpm, system failures, speed, and the time at which
> certain events occur can often be determined. Communications with Air
> Traffic Control, automated radio weather briefings, and conversation between
> the pilots and ground or cabin crew are also recorded."
> [NTSB web site <A HREF="http://www.ntsb.gov/aviation/CVR_FDR.htm">http://www.ntsb.gov/aviation/CVR_FDR.htm</A>]
> Regarding the Flight Data Recorder it says: "The FDR onboard the aircraft
> records many different operating conditions of the flight. By regulation,
> newly manufactured aircraft must monitor at least twenty eight important
> parameters such as time, altitude, airspeed, heading, and aircraft attitude.
> In addition, some FDRs can record the status of more than 300 other
> in-flight characteristics that can aid in the investigation. The items
> monitored can be anything from flap position to auto-pilot mode or even
> smoke alarms."
> [NTSB web site <A HREF="http://www.ntsb.gov/aviation/CVR_FDR.htm">http://www.ntsb.gov/aviation/CVR_FDR.htm</A>]
> Thus as we see each plane is equipped with two seperate "Black Box" devices
> which relay different yet complimentary information. It goes on to say:
> "Both the Flight Data Recorder and the Cockpit Voice Recorder have proven to
> be valuable tools in the accident investigation process. They can provide
> information THAT MAY BE DIFFICULT TO OBTAIN BY OTHER MEANS."
> [NTSB web site <A HREF="http://www.ntsb.gov/aviation/CVR_FDR.htm">http://www.ntsb.gov/aviation/CVR_FDR.htm</A>]
> They are meant to be the hardy and sure way to get information regarding the
> last minutes before the plane went down. Here are the specifications of
> these devices including what they can withstand:
> FLIGHT DATA RECORDER Time recorded: 25 hour continuous Number of parameters:
> 5 - 300+ Impact tolerance:
> 3400Gs /6.5ms Fire resistance: 1100 degC/30 min Water
> pressure resistance: submerged 20,000 ft Underwater
> locator beacon: 37.5 KHz Battery: 6yr shelf life 30
> day operation
>
>
> COCKPIT VOICE RECORDER Time recorded: 30 min
> continuous, 2 hours for solid state digital units
> Number of channels: 4 Impact tolerance: 3400 Gs /6.5ms
> Fire resistance: 1100 deg C /30 min Water pressure
> resistance: submerged 20,000 ft Underwater locator
> beacon: 37.5 KHz Battery: 6yr shelf life 30 day
> operation
> These specifications indicate equipment which can survive just about any
> conditions and any crash. Indeed, Black Boxes have been recovered from
> crashes in swamps, mountains, and oceans.
> ABC News reports: "Although investigators look for an entire black box,
> sometimes the only parts of the device that survive are the recorder's
> crash-survivable memory units (CSMU).
> THE CSMU IS ALMOST INDESTRUCTABLE. It is housed within a stainless-steel
> shell that contains titanium or aluminum and a high-temperature insulation
> of dry silica material." "It is designed to withstand HEAT OF UP TO 2,000
> DEGREES FAHRENHEIT FOR ONE HOUR, salt water for at least 30 days, immersion
> in a variety of liquids such as jet fuel and lubricants, AND AN IMPACT OF
> 3,400 G's. By comparison, astronauts are typically exposed to up to six Gs
> during a shuttle takeoff." [ABCNews -

> So the Black Box is designed to withstand an impact of 3,400 G's. So what
> about the Pennsylvania crash site? "THE VOICE RECORDER WAS SAID TO BE
> HEAVILY DAMAGED, and the manufacturer was being asked to help with further

> The plane hit the ground at 500 mph. Taking the weight of the plane, its
> speed of descent, the G's end up much, much lower than 3,400. Since each

> are to believe that all the Black Boxes were damaged beyond use, then that

> Then the final paragraph of the same article says:
> "Investigators are less confident they will recover the black boxes buried

> So there is no hope of recovering the virtually indestructable Black Box
> from the rubble, but a paper passport survives in such a perfect state that
> it is "a significant piece of evidence"?
> CNN reports one of the hijackers passports was found in the rubble of the

> Aside from the idiocy of any suggestion that a passport would survive a

> Why a few blocks away?
> Could it be because it was a place out of everyone's sight?
> It is also well known that paper was strewn all over the scene of the plane
> crash. This was due to the sudden shattering of the windows which would
> immediately eject all paper materials out of the building before
> incineration.
> A passport in someone's pocket who is sitting on a plane that explodes will

> United Airlines flight 93 crashed into a field in Pennsylvania. There was no
> explosion and no impact into a building and no 100+ story towers crashed
> down on top of it. Yet, we are led to believe that both of its Black Boxes
> were destroyed and/or damaged beyond use as well. Other airline tragedies
> also reveal that in each and every case the Black Box is recovered, albeit
> damaged, but with full usability. Such crashes include EgyptAir flight 990,
> a 767, and TWA flight 800, a 747. Both crashes resulted in tremendous
> compromise of the planes physical integrity, but in spite of this the
> Cockpit Voice Recorders were recovered. So we have established that the
> survival of a passport of someone in an exploded plane is lunacy.
> However, for the sake of argument lets say the passport survived. If the
> passport did indeed survive then so did the Black Box. If the Black Box did
> indeed survive as we have proven beyond a shred of doubt, then why the
> complete and utter lie that it was damaged beyond use?
