9/11: PENTAGON AIRCRAFT HIJACK IMPOSSIBLE FLIGHT DECK DOOR CLOSED FOR ENTIRE FLIGHT

One would really have to know exactly how the door was constructed to come to the conclusion that the hijackers did not have access to the cockpit.

Where were the sensors located on the door?

It could be possible that the door was broken in such a way that the sensors were left intact.

There is also the possibility that particular system was not working properly. Before 911 maintenance on that particular system might not have been a priority.

But as this fits your agenda of course you will state it as a "given".

And that is my problem with most so called "truthers".

To look at only what they think tells the story and not a thorough look at clues, only what fits their agenda. And that was basically to say anything bad possible and quite a few things made up about an administration they had a profound and open hatred for even before they took office.

So,

you would have to show me a lot more than one friggen door sensor to say the hijackers did not have access to the cockpit.

For one you would have to examine all maintenance records for that aircraft and any pilot comments made on aircraft defects.

Another is that the door COULD NOT be broken in such a way as to NOT make the sensor show the door was open.

By the same token GH, you cannot evne prove by your own stated methods that there were even any hi-jackers in the cockpit, can you? You were not there, and neither was I. we did not see all there was to see and hear either.

I am not convinced there ever were any hijackers.

The FBI stated that they were aware that the 'id's were fake, but have never bothered to tell anyone who the real alleged hijackers' ids were... they just let all thos arabic names dangle out their, after stating they knew the passports were fake ids.

In truth, the perfect conspiarcy has been pulled off, just as one was in the JFK assassination. A majority would never believe the truth, whatever it is now.

Let's just keep to the topic shall we?

The flight recorder actually had 42 flight hours in it.

None of the flight time EVER showed the door open during flight.

But more importantly.

The flight recorder system was manufactured in 1997 so it was an update for this particular recorder system.

The aircraft was built in 1991 and did not actually have a door sensor.

The FDR shows 0's for the flight door because it was an unused block.

Your thread topic has just been debunked.

Sorry.

you didn't debunk anything, you just showed how little you know, this is from pilots for the truth forum:


"The FLT DECK OPEN parameter was not added to the FDR frame (757-3 A2) until 1997. The plane was manufactured in 1991 using an earler frame structure which did not include the parameter, so a binary 0 for an unused data block."


This claim is wrong because actually all the FDR system has been updated before 08/18/2001...

According to [link to www.boeing.com]

Airplanes manufactured before October 11, 1991, with an FDAU or DFDAU as of July 16, 1996.

AIRPLANES MANUFACTURED PRIOR TO OCTOBER 11, 1991, WITHOUT AN FDAU OR DFDAU INSTALLED AS OF JULY 16, 1996.
The new rule requires that by August 18, 2001 the FDR record at least 18 parameter groups. For most airplanes, this is an increase from 11 parameter groups, as described in "Effects of 1989 FAA Flight Data Recorder Rule Change" on page 32.

The new rule requires that by four years from date of rule at least 22 parameter groups be recorded by the FDR. In this group are Boeing models 727, 737, 747, 757, 767, DC-10, and MD-80.

Not so fast:

The aircraft was manufactured before October 11 1991.

The rule for these aircraft is:

AIRPLANES MANUFACTURED PRIOR TO OCTOBER 11, 1991, WITHOUT AN FDAU OR DFDAU INSTALLED AS OF JULY 16, 1996.
The new rule requires that by August 18, 2001 the FDR record at least 18 parameter groups. For most airplanes, this is an increase from 11 parameter groups, as described in "Effects of 1989 FAA Flight Data Recorder Rule Change" on page 32. On about half of all the Boeing 727, 737, DC-8, and DC-9 models the FDR system uses a single FDR, a result of the late 1980s replacement activity. Most of these FDRs should have enough spare inputs to accommodate the increased requirements with little or no modification required. Other parameter groups required to be recorded include the addition of both flight control surface positions and flight control inputs for all three axes (lateral, directional, longitudinal), lateral acceleration, and autopilot engagement status. Airplanes manufactured prior to October 11, 1991, with a FDAU or DFDAU installed as of July 16, 1996. The new rule requires that by four years from date of rule at least 22 parameter groups be recorded by the FDR. In this group are Boeing models 727, 737, 747, 757, 767, DC-10, and MD-80. Most of these airplanes record almost all the 22 parameter groups, some of which operators may ask Boeing to remove to save weight or to avoid maintenance costs if a parameter group is not required by a particular country's regulatory agency. The additional parameter groups required to be recorded include the addition of flight control surface positions and flight control inputs for all three axes, lateral acceleration, and autopilot engagement status.

Let me repeat this:

The new rule requires that by August 18, 2001 the FDR record at least 18 parameter groups.

If you read the rest of it you will glean that later aircraft will require 34, 57, or 88 parameter groups to be recorded.

The door sensor is not required on the earlier aircraft but they COULD have a flight recorder installed that had the capacity for more parameters, but they were unused blocks.

Or possibly it might have had to record 22 parameters, but that is still much less than the 34, 55, or 88 parameter capable recorders.

Feel free to provide a list of EXACTLY what the required 22 parameters were.

i cant believe its not getting the attention here that it is at so many other places.......


That's because this is a shill forum with moderators who are more interested in Muslim bashing than the Truth Movement.

No need really.

Of the 22 parameters, the flight door is not one of them.

If YOU can prove otherwise please feel free to do so.

I mean YOU peole claim this as a given when it really isn't.

So, You honestly did no debunking, really you just provided another question, and Hole to the story provided by the Government..


The OS is beginning to look like Swiss Cheese.

OK,

it took a little digging but I found what the required 22 parameters for that aircraft would have been.

(1) Time;

(2) Pressure altitude;

(3) Indicated airspeed;

(4) Heading -- primary flight crew reference (if selectable, record discrete, true or magnetic);

(5) Normal acceleration (Vertical);

(6) Pitch attitude;

(7) Roll attitude;

(8) Manual radio transmitter keying, or CVR/DFDR synchronization reference;

(9) Thrust/power of each engine -- primary flight crew reference;

(10) Autopilot engagement status;

(11) Longitudinal acceleration;

(12) Pitch control input;

(13) Lateral control input;

(14) Rudder pedal input;

(15) Primary pitch control surface position;

(16) Primary lateral control surface position;

(17) Primary yaw control surface position;

(18) Lateral acceleration;

(19) Pitch trim surface position or parameters of paragraph (a)(82) of this section if currently recorded;

(20) Trailing edge flap or cockpit flap control selection (except when parameters of paragraph (a)(85) of this section apply);

(21) Leading edge flap or cockpit flap control selection (except when parameters of paragraph (a)(86) of this section apply);

(22) Each Thrust reverser position (or equivalent for propeller airplane); (1)



This is from:

[link to www.risingup.com]

Note that the cockpit flight door is NOT listed.

So the recorder was capable of more parameters than there were sensors for.

The parameter for the cockpit flight door was an unused block.

Note that it is far more expensive to install and wire the sensors than to use a generic flight recorder capable of more parameters.

So anyway, the OP's claim or thread title is DEBUNKED.

If you show your proof to the ones who originated this story and they have no reply then i'll have no alternative but to believe you. Untill then it's still up in the air (excuse the pun).

I do not have the knowledge to know either way so i would be interested to know the real truth once and for all.

The 9/11 crash videos are fake, but that doesn't seem to be huge news either, because people are sheep and have no consideration for truth.
