You sir are a punk.

The Flt 93 black boxes were small, light-weight, of relatively the same size, and located next to each other in the tail of the aircraft.
Common sense dictates that the tail section of the aircraft allegedly and officially flying upside-down and diving into the ground at a 40 degree angle from the horizontal... *skipping drivel*... would have broken off when the tail hit the ground and tumbled away carrying the black boxes with it, and shattering across the surface
Even if the tail of the aircraft had entered the strip mine following the previous mass of the aircraft; why would the light-weight black boxes be buried deeper than the alleged multi-ton turbofan engine allegedly found mere inches below the surface?
And with no serial numbers from the Flt 93 black boxes proving where they came from nor the identity of the aircraft, and in fact not one single serial number from any of the four alleged 9-11 aircraft proving aircraft identity or black box or any single individual part; these alleged black boxes are bogus. The Flt 93 black box photos could have been taken anywhere in the world; even in Italy ...
The Flight Data Recorder collects data from a number of sensors to monitor information like accelerations, airspeed, altitude, .ing, attitudes, cockpit control positions, thermometers, engine gauges, fuel flow, control surface positions, autopilot status, switch positions, and a variety of other parameters. Most parameters are recorded a few times per second but some FDRs can record bursts of data at higher frequencies when inputs are changing rapidly.
The data measured by the different sensors is collected by the Flight Data Acquisition Unit (FDAU). This device is typically located in an equipment bay at the front of the aircraft beneath the flight deck. The FDAU assembles the desired information in the proper format and passes it on to the FDR at the rear of the plane for recording. The Federal Aviation Administration (FAA) required the FDR to record between 11 and 29 parameters, depending on aircraft size, up to 2002 but now requires saving a minimum of 88 sets of data. Analog FDRs can save a maximum of around 100 variables while digital recorders are often capable of collecting over 1,000 parameters over the course of 25 hours.

** skipped extraneous info **
...A common misconception states that the black boxes are "indestructible." No manmade device is indestructible, and no material has ever been developed that cannot be destroyed under severe enough conditions. The black boxes are instead designed to be highly survivable in a crash. In many of the worst aviation accidents, the only devices to survive in working order are the Crash Survivable Memory Units (CSMUs) in the black boxes. The remainder of the recorders, including the external case and other internal components, are often heavily damaged.
Interior cut-away of a black box design
The CSMU, however, is contained within a very compact cylindrical or rectangular box designed to safeguard the data within against extreme conditions. The box is composed of three layers to provide different types of protection to the recording medium. The outermost shell is a case made of hardened steel or titanium designed to survive intense impact and pressure damage. The second layer is an insulation box while the third is a thermal block to protect against severe fire and heat. Together, these three layered cases allow the FDR and CVR to survive in all but the most extreme crash conditions.
Current regulations require the black boxes to survive an impact of 3,400 g's for up to 6.5 milliseconds. This rapid deceleration is equivalent to slowing from a speed of 310 miles per hour (500 km/h) to a complete stop in a distance of just 18 inches (45 cm). This requirement is tested by firing the CSMU from an air cannon to demonstrate the device can withstand an impact force at least 3,400 times its own weight. The black boxes must also survive a penetration test during which a steel pin dropped from a height of 10 ft (3 m) impacts the CSMU at its most vulnerable point with a force of 500 pounds (2,225 N). In addition, a static crush test is conducted to demonstrate that all sides of the CSMU can withstand a pressure of 5,000 pounds per square inch (350 kg/cm²) for five minutes. The fire resistance of the CSMU is further tested by exposing it to a temperature of 2,000°F (1,100°C) for up to an hour. The device is also required to survive after lying in smoldering wreckage for ten hours at a temperature of 500°F (260°C).
Another factor important to the survivability of the black boxes is their installation in the tail of the aircraft. The exact location often varies depending on the plane, but the FDR and CVR are usually placed near the galley, in the aft cargo hold, or in the tail cone.
The recorders are stored in the tail since this is usually the last part of the aircraft to impact in an accident. The entire front portion of the plane acts like a crush zone that helps to decelerate the tail more slowly. This effect reduces the shock experienced by the recorders and helps to cushion the devices to improve their chances of surviving the crash.
Once the black boxes have been located following an accident, they are typically taken into custody by an aviation safety agency for analysis. In the United States, responsibility for investigating most air accidents belongs to the National Transportation Safety Board (NTSB). Many countries lacking the capability to analyze black boxes also send their recorders to the computer labs of the NTSB or some of the better-equipped investigative organizations in Western nations. Care must be taken in recovering and transporting the recorders so that no further damage is done to the devices that might prevent important data from being extracted.
Upon receipt of the recorders, the NTSB uses a series of computer and audio equipment to process and analyze any information that can be recovered. The data is translated into formats readily usable by investigators and is usually critical in identifying the probable cause(s) of the accident. This process may take many weeks or months depending on the condition of the black boxes and the level of processing required to make sense of the data. Outside experts are also often consulted to help analyze and interpret the data.
The evidence taken in its entirity is overwhelming; an aircraft did not bury itself in that strip mine and disappear.
There is no chain of custody on anything.
Alleged official photos of alleged Flt 93 aircraft debris cannot be traced nor verified as to authenticity.
There was no jet fuel in the soil contaminating the ground water.

But these find folks are all dillusional (sic) as well, right?
and include myslef in that mix as I am a defense contractor who also has 18 years of military/government experience...and here's an eye opener for you, 9/11 is a dirty little secret in the defense community. We don't openly talk about it or bring it up, but trust me when I say that there are many still in the business of "war" who know that 9/11 was a perpetuated sequence of greed, lies, and deciet (sic).
I'm aware of are the idiots who denigrate the memories of those who died on 9/11 and who accuse the Pentagon and military establishment itself of executing this. Like you! And CIT. And PfT. And AE911.

Even if the tail of the aircraft had entered the strip mine following the previous mass of the aircraft; why would the light-weight black boxes be buried deeper than the alleged multi-ton turbofan engine allegedly found mere inches below the surface? And assuming that the mass of the fuselage containing seats, passengers, landing gear, baggage, fuel, and crumpled aluminum was buried a. of them; how could one light-weight black box be officially buried at 15 feet, and the other light-weight black box be officially buried at 25 feet? Sounds fishy to me. How did those black boxes get past all of that alleged aircraft mass buried a. of them?

SPreston would have us believe that the kinetic energy (momentum) of the empennage section of the airplane would allow it to suddenly make an acute angle change of direction and travel off, rather than continuing on its previous trajectory into the ground. His 'theory' defies the laws of physics!!
9-11 was most definitely an INSIDE JOB and the 9-11 OFFICIAL STORY is bogus.

I guess you could say I'd fall into more readily believing the "LIHOP" mindset (not saying I do, yet) than the "MIHOP", or 'staged/faked' crowd.
IN FACT, to be honest, since I do see "LIHOP" as more plausible, (and WAY, WAY above the little minds of someone like our former Presidents), then the noise from the other camp is actually getting in the way, I think.
