Passenger lists don't show names of these 19. Nothing has been heard about what happened to the planes' black boxes. Hard NOT to believe it's a conspiracy: The 911 Black Boxes
'Did Not Survive'
The Media News.com
10-18-3

And even if we forget the WTC steel, there's the curious incident of the planes' black boxes - not ONE of the EIGHT black boxes - two per plane - survived! Not just those of the planes that crashed into the Twin Towers, but also of the other two planes! Not even of the one that crashed into the ground in Pennsylvania.

Do you know the kind of crash these black boxes are designed to withstand? 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]

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]

Thus as we see each plane is equipped with two separate "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]

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 indestructible. 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 analysis. The plane that crashed in Pennsylvania was reported to have hit the ground in excess of 500 miles per hour." [ABCNews]

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 plane has two separate Black Boxes which are designed to be indestructible in the event of a tragedy, that makes a total of eight black boxes. We are to believe that all the Black Boxes were damaged beyond use, while a measly paper passport survived!

Missing Evidence About the September 11th Flights
Flight data recorders (FDRs) record the readings of instruments and positions of the aircraft's control surfaces over time. They are contained in "black boxes" that are designed to survive the worst crashes. The same black boxes also contain the cockpit voice recorders. To date, none of the contents of any of the black boxes have been released to the public, authorities having claimed that all but the recorders on Flight 93 were either not recovered or too damaged to yield data. The black box of Flight 77 was allegedly found on September 14th, but yielded "nothing useful" according to FBI director Robert Mueller. 1 2

Survivability Requirements
Events that would damage the recorders sufficiently to make them unreadable are extremely rare. The recorders are designed to survive the kinds of impacts that happened at the World Trade Center and the Pentagon.

The FAA has placed durability requirements on the recorders and their casings to survive severe impact and fire

The storage medium of each recorder is located in a protective capsule, which must be able to withstand an impact of 3,400 Gs (3,400 times the force of gravity). Additionally, each must also survive flames at 2,000 F for up to 30 minutes, and submersion in 20,000 feet of saltwater for 30 days. Typically, to increase their chances of survival, the recorders are located in the tail section of the aircraft, which usually sustains the least impact in a crash.

In light of the evidence against Bush on his failure to protect the nation, all the events of 9/11 should be looked into: On TV Worldwide, But 4 of 4 Top Officials Clueless
What were the President, Vice President, Secretary of Defense, and Chairman of the Joint Chiefs of Staff doing while Air Force pilots awaited their commands? Supposedly they learned about the attack over 30 minutes later than anyone watching TV. Each has a story of what they were doing during the critical hour when the air defense network stood down.

George W. Bush
General Myers
Donald Rumsfeld
Dick Cheney
Of these four officials, all pretend they did not grasp what was unfolding until shortly before the Pentagon was hit at 9:43, even though the story of the attack had gone live on local television stations across the nation by 9 AM. 1 Cheney was in the White House and Rumsfeld was in the Pentagon -- two of the command and control centers of the U.S. military. The Cheyenne Mountain official website described NORAD's Command Center:

Redundant and survivable communications hotlines connect the Command Center to the Pentagon, White House, U.S. Strategic Command, Canadian Forces Headquarters in Ottawa, other aerospace defense system command posts, and major military centers around the world.

Bush is always surrounded by his Secret Service detail, whom would presumably be aware of current events, and Myers was on Capital Hill in a scheduled meeting, and hence easily locatable

Flight Routes The only plausible explanation is that the perpetrators were aware that the air defense system would be stood down.

Hijackers Flaunt Air Superiority With Long Detours
The four planes commandeered on September 11th either flew to their targets from distant airports, or flew hundreds of miles away from their targets before turning around. There are three international airports within five minutes flying distance from the World Trade Center. Yet the hijackers selected Flights 11 and 175 originating from Boston, 40 minutes away. Flight 77, took off from Dulles, just a few miles from its alleged target, the Pentagon. Yet they waited almost until the plane reached Kentucky before taking it over. Flight 93 took off from Newark. If the hijackers had taken it over shortly after takeoff, they could have reached Washington in about 30 minutes. Instead they waited until it was near Cleveland, Ohio, before turning it around.

Anyone planning such an attack could easily find out, with the just a modicum of research on the web, that standard operating procedures would lead to interception by a fighter jet within about 20 minutes of any airliner hijacked in the northeast corridor. By choosing originating airports over one hundred miles from their targets in three of four cases, and waiting for nearly a half hour in all four cases before taking over the flights, the perpetrators exposed the entire plot to certain interruption had the air defense system operated normally. The only plausible explanation is that the perpetrators were aware that the air defense system would be stood down.

Like Ritter, O'Neill, now Clarke, maybe there is someone who will come forward with the truth about 9/11 - if they're still alive: NORAD Stand-Down
The Prevention of Interceptions of the Commandeered Planes
It is standard operating procedure (SOP) to scramble jet fighters whenever a jetliner goes off course or radio contact with it is lost. Between September 2000 and June 2001, fighters were scrambled 67 times. 1

There are several elements involved in domestic air defense. The air traffic control system continuously monitors air traffic and notifies NORAD of any deviations of any aircraft from their flight-paths or loss of radio contact. NORAD monitors air and space traffic continuously and is prepared to react immediately to threats and emergencies. It has the authority to order units from the Air National Guard, the Air Force, or other armed services to scramble fighters in pursuit of jetliners in trouble.

Routine interception procedures were not followed on September 11th, 2001. This can be seen clearly by comparing incidents.

A Case for Comparison
An example of how the air defense network normally responds to domestic emergencies is illustrated by the well-reported 1999 case of Payne Stewart's Lear jet. When the golfer's jet failed to respond to air traffic controller communications, F-16 interceptors were quickly dispatched. According to an Air Force timeline, a series of military planes provided an emergency escort to Payne's stricken Learjet starting about 20 minutes after contact with his plane was lost. 2

This contrasts with the long periods of time apparently hijacked planes roamed the skies of the Northeast on September 11th without any interceptions. 83 minutes elapsed between the time that Flight 11 veered off course and the Pentagon was hit, and 112 minutes elapsed between the time that contact was lost with Flight 11 and Flight 93 crashed. According to the official story, not a single fighter was scrambled in time to intercept any of the four jetliners. At least 28 air stations were easily within distance to protect New York City and Washington DC. 3 None of them did. Note that, if anything, intercept times for the four jetliners should have been far shorter than for Payne Stewart's jet:

Stewart's jet merely failed to respond to communications. Each of the four jetliners, in addition to going silent, veered dramatically off course and switched off their transponders.
Stewart's jet went off course in the South, which has fewer air defense stations than the NorthEast corridor.
Air traffic controllers more carefully monitor large passenger aircraft in crowded air corridors than small private aircraft.
Stewart's jet went off-course at 45,000 feet, 10,000 feet higher than jetliners fly.
After the first hijacking, the air traffic controllers, the FAA, and NORAD should have been prepared to respond immediately to subsequent off-course aircraft.

Layered Failures
The air defense network had, on September 11th, predictable and effective procedures for dealing with just such an attack. Yet it failed to respond in a timely manner until after the attack was over, more than an hour and a half after it had started. The official timeline describes a series of events and mode of response in which the delays are spread out into a number of areas. There are failures upon failures, in what might be described as a strategy of layered failures, or failure in depth. The failures can be divided into four types.

Failures to report: Based on the official timeline, the FAA response times for reporting the deviating aircraft were many times longer than the prescribed times.
Failures to scramble: NORAD, once notified of the off-course aircraft, failed to scramble jets from the nearest bases.
Failures to intercept: Once airborne, interceptors failed to reach their targets because they flew at small fractions of their top speeds.
Failures to redeploy: Fighters that were airborne and within interception range of the deviating aircraft were not redeployed to pursue them.
Had not there been multiple failures of each type, one or more parts of the attack could have been thwarted. NORAD had time to protect the World Trade Center even given the unbelievably late time, 8:40, when it claims to have first been notified. It had time to protect the South Tower and Washington even given its bizarre choice of bases to scramble. And it still had ample opportunity to protect both New York City and Washington even if it insisted that all interceptors fly subsonic, simply by redeploying airborne fighters.

Failures to Report
Comparing NORAD's timeline to reports from air traffic control reveals inexplicable delays in the times the FAA took to report deviating aircraft. The delays include an 18-minute delay in reporting Flight 11 and a 39-minute delay in reporting Flight 77. The delays are made all the more suspicious given that, in each case, the plane failed to respond to communications, was off-course, and had stopped emitting its IFF signal.

Failures to Scramble
No plausible explanation has been provided for failing to scramble interceptors in a timely fashion from bases within easy range to protect the September 11th targets. Fighters that were dispatched were scrambled from distant bases. Early in the attack, when Flight 11 had turned directly south toward New York City, it was obvious that New York City and the World Trade Center, and Washington D.C. would be likely targets. Yet fighters were not scrambled from the bases near the targets. They were only scrambled from distant bases. Moreover there were no redundant or backup scrambles.

New York City
Flight 11 had been flying south toward New York City from about 8:30 AM. Yet no interceptors were scrambled from nearby Fort Dix or Laguardia, or from Langley, Virginia. Numerous other bases were not ordered to scramble fighters.

Washington D.C.
No interceptors were scrambled from Andrews Air Force Base to protect the capital, at least not before the Pentagon was hit. Andrews Air Force Base had two squadrons of fighters on alert, and is only 10 miles from the Pentagon.

Failures to Intercept
Even though the interceptors were not dispatched from the most logical bases, the ones that were scrambled still had adequate time to reach their assigned planes. Why didn't they? Because they were only flying at a small fraction of their top speed. That is the conclusion implicit in NORAD's timeline.

Otis to the WTC
The first base to finally scramble interceptors was Otis in Falmouth, Massachusetts, at 8:52, about a half-hour after Flight 11 was taken over. This was already eight minutes after Flight 11 hit the North Tower, and just 9 minutes before Flight 175 hit the South Tower.

According to NORAD, at the time of the South Tower Impact the two F-15s from Otis were still 71 miles away. Otis is 153 miles east-northeast of the WTC. That means the F-15s were flying at: (153 miles - 71 miles)/(9:03 - 8:52) = 447 mph
That is around 23.8% of their top speed of 1875 mph.
At 9:11 the F-15s finally reached the World Trade Center. Their average speed for the trip was: 153/(9:11 - 8:52) = 483 mph
That is around 25.8% of their top speed.

Langley to the Pentagon
The F-16s from Langley reached the Pentagon at 9:49. It took them 19 minutes to reach Washington D.C. from Langley AFB, which is about 130 miles to the south. That means the F-16s were flying at: 130 miles/(9:49 - 9:30) = 410.5 mph
That is around 27.4% of their top speed of 1500 mph.

Andrews to the Pentagon
Andrews Air Force Base, located on the outskirts of the capital, is just over 10 miles from the Pentagon. One would have expected interceptors to be scrambled to protect the capital within a few minutes of the 8:15 loss of contact with Flight 11. Instead, no fighters from Andrews reached the Pentagon until 9:49, several minutes after the assault.

Failures to Redeploy
Fighters that were in the air when the attack started were not redeployed to intercept the deviating planes. When fighters scrambled to protect Manhattan arrived there too late, they were not redeployed to protect the capital even though they had plenty of time to reach it before the Pentagon was hit.

Long Island to Manhattan
Two F-15s flying off the coast of Long Island were not redeployed to Manhattan until after the second tower was hit. 4

WTC to the Pentagon
By the time the two F-15s from Otis reached Manhattan, the only jetliner still flying with its IFF transponder off had just made a 180-degree turn over southern Ohio and had been headed for Washington D.C. for 12 minutes. It was still 34 minutes before the Pentagon was hit. Had the fighters been sent to protect the capital, they could have traveled the approximately 300 miles in: 300 miles/1875 mph = 9.6 minutes
They even could have made it to the capital in time to protect the Pentagon if they had continued to fly at only 500 mph.
