Recovering the Black Boxes
A Flight Data Recorder or “Black Box” as they are often referred to helps aviation investigators determine the cause of airline crashes. Flight Data Recorders are engineered to withstand the forces of high speed impacts and the heat of intense fires including those caused by jet fuel explosions and buringing.
Flight Data Recorders are not actually Black Boxes, rather they are brightly colored in a very visible shade of orange. The purpose of which is to allow the devices to be easily seen during the recovery process.
In the United States, the Federal Aviation Administration (FAA) regulates all aspects of U.S. aviation, and cites design requirements in their Technical Standard Order, based on the EUROCAE documents (as do the aviation authorities of many other countries).
Flight Data recorders in commercial jetliners are placed in the tail section of the aircraft. The reason of course is to minimize the impact and damage to the boxes themselves as most planes will crash nose first. This also puts the devices far behind the fuel storage tanks. The sensors and data acquisition units which feed the flight data recorders information such as acceleration, engine performance, airspeed, flap settings, temperature, cabin pressure, etc. are located in various places in the aircraft.
In commercial aircraft there are microphones built into the cockpit and voice recorders to capture and track what is said by the pilots as they communicate with air traffic control. These devices also record ambient noise such the movement of switches.
The flight voice recorders contain microphones in the pilot and copilot headsets and crew members that sit in the cockpit if present.
Flight Data Recorders are required to pass a number of tests including:
- Crash Impact
- Static Crush
- Pin Drop
- Fire Test
- DeepSea Submersion
- Salt Water Submersion
- Fluid Immersion
The specifics of which go beyond the scope of what I am trying to present to you here. One test in particular you should pay close attention to and that is the Fire Test.
Fire Test - Researchers place the unit into a propane-source fireball, cooking it using three burners. The unit sits inside the fire at 2,000 degrees Fahrenheit (1,100 C) for one hour. The FAA requires that all solid-state recorders be able to survive at least one hour at this temperature.
One hour at a consistent 2,000 degrees Fahrenheit!
Now the punch line. Each jet that crased into the World
Trade Centers contained 2 flight data recorders. The official 911 report states that the
flight recorders were never found. Boxes
that are designed to withstand 3,400 G’s of force and burn for an hour at a
consistent temperature of 2,000 degrees Fahrenheit! However, bone fragments of individuals killed
in the blast were found and in good enough shape to test for DNA
identification. Odd that bone fragments
of a human body would be identifiable, but not one of the 4 flight data
recorders was found. Humans are more Fire Proof than Fire Proof boxes?
You can draw your own conclusions. For me I have to side with the people that know the truth. The boxes were discovered and are in possession of the FBI and the Federal Government Refuses to admit this because there is incriminating evidence contained on the flight data recorders.
Why was the Air Force ordered to Stand Down?
In 1999, when golf pro Payne Stewart's small PRIVATE Lear jet went off-course and out of communication just after takeoff in Florida.Within MINUTES, on an immediate alert from the FAA, U.S. Air Force and Air Guard jets were scrambled to intercept Stewart's jet and see what the heck was up "Several Air Force and Air National Guard fighter jets, plus an AWACS radar control plane, helped the Federal Aviation Administration track the runaway Learjet and estimate when it would run out of fuel." --CNN, 10.26.99
Again you can draw your own conclusions. Might want to research “False Flag” operations.
Blind Trust in Government is your choice.
I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them. -- Thomas Jefferson
