- Hi Jeff,
-
- I had better chime-in to counter the blatant falsehoods
from this story on your site.
-
- Here are the easiet de-facto falsehoods to point out:
-
- ** The Boeing 757 and 767 are equipped with fully autonomous
flight capability, they are the only two Boeing commuter aircraft capable
of fully autonomous flight.
-
- While many airplanes have automatic landing capability
(more than just 757/767) there are NO commercial airliners that are "fully
autonomous". For example, the FAA has no certification guidelines
for certifying things like automated landing gear, automated flaps, etc.
All of these systems are required to be operated by human pilots to put
the airplane in a landing configuration.
-
- Furthermore, there are NO airplanes that have an automatic
takeoff capability. It can be done, but the operational considerations
are what has prevented the FAA from adopting certification guidelines until
only the last few years. And even though there are guidelines of how to
certify auto takeoff, no one has done it.
-
-
- ** They can be programmed to take off, fly to a destination
and land, completely without a pilot at the controls.
-
- Complete baloney. The anonymous writer does not know
anything about commercial airplane design.
-
-
- ** They are intelligent planes, and have software limits
pre set so that pilot error cannot cause passenger injury.
-
- Wrong again! The ONLY airplanes that have software-imposed
HARD LIMITS on flight maneuvers are the A320, A330, and A340 series of
Airbus airplanes. The design philosophy of Boeing in this area has ALWAYS
been "soft limits" that the pilot can exceed given his/her discretion.
Force deterrents on the control yoke are used to give the pilot a "hint"
that they are exceeding the flight envelope. However, Boeing does NOT
impose hard limits.
-
-
- **Though they are physically capable of high g maneuvers,
the software in their flight control systems prevents high g maneuvers
from being performed via the cockpit controls.
-
- Incorrect. This is half-truth. Such limits ARE imposed
on the AUTOPILOT. However, once the pilot disconnects the autopilot, the
pilot has full maneuver authority within the MECHANICAL limits of the flight
control actuation system.
-
- I will not go any further, for the rest is ridiculous
claptrap.

- The Boeing 757 and 767 are equipped with fully autonomous
flight capability, they are the only two Boeing commuter aircraft capable
of fully autonomous flight. They can be programmed to take off, fly to
a destination and land, completely without a pilot at the controls.
-
- They are intelligent planes, and have software limits
pre set so that pilot error cannot cause passenger injury. Though they
are physically capable of high g maneuvers, the software in their flight
control systems prevents high g maneuvers from being performed via the
cockpit controls. They are limited to approximately 1.5 g's, I repeat,
one and one half g's. This is so that a pilot mistake cannot end up breaking
grandma's neck.
-
- No matter what the pilot wants, he cannot override this
feature.
-
- The plane that hit the Pentagon approached or reached
its actual physical limits, military personnel have calculated that the
Pentagon plane pulled between five and seven g's in its final turn.
-
- The same is true for the second aircraft to impact the
WTC.
-
- There is only one way this can happen.
-
- As well as fully autonomous flight capability, the 767
and 757 are the ONLY COMMUTER PLANES MADE BY BOEING THAT CAN BE FLOWN VIA
REMOTE CONTROL. It is a feature that is standard to all of them, all 757's
and 767's can do it. The purpose for this is if there is a problem with
the pilots, Norad can fly the planes to safe destinations via remote. Only
in this flight mode can those craft exceed their software limits and perform
to their actual physical limits because a pre existing emergency situation
is assumed if this mode of flight is used.
-
- Terrorists in fact did not fly those planes, it is totally
and completely impossible for those planes to have been flown in such a
manner from the cockpit. Those are commuter aircraft, not F-16's and their
software knows it.
-
- Another piece of critical evidence: the voice recorders
came up blank.
-
- The flight recorders that were recovered had tape that
was undamaged inside, but it was blank. There is only one way this can
happen on a 757 or 767. When the aircraft are commandeered via remote control,
the microphones that go to the cockpit voice recorder are re routed to
the people doing the remote controlling, so that the recording of what
happened in the cockpit gets made in a presumably safer place. But due
to a glitch in the system on a 757/767, rather than shutting off when the
mic is redirected the voice recorder keeps running. The voice recorders
use what is called a continuous loop tape, which automatically re passes
itself past the erase and record heads once every half hour, so after a
half hour of running with the microphones redirected, the tape
- will be blank. Just like the recovered tapes were. Yet
more proof that no pilot flew those planes in the last half hour.
-
- Eight of the hijackers who were on those planes called
up complaining that they were still alive. I'd bet you never heard about
our foreign minister flying to Morocco and issuing an official apology
to the accused, did you? No, terrorists did not fly those planes, plastic
knives and box cutters were in fact too ridiculous to be true. Any of the
remaining accused have certainly been sought out and killed by now.
-
- Our information IS controlled
-
- The cell phone calls from the aircraft could not have
happened. I am a National Security Agency trained Electronic Warfare specialist,
and am qualified to say this. My official title: MOS33Q10, Electronic Warfare
Intercept Strategic Signal Processing/Storage Systems Specialist, a highly
skilled MOS which requires advanced knowledge of many communications methods
and circuits to the most minute level. I am officially qualified to place
severe doubt that ordinary cell phone calls were ever made from the aircraft.
-
- It was impossible for that to have happened, especially
in a rural area for a number of reasons.
-
- When you make a cell phone call, the first thing that
happens is that your cell phone needs to contact a transponder. Your cell
phone has a max transmit power of five watts, three watts is actually the
norm. If an aircraft is going five hundred miles an hour, your cell phone
will not be able to 1. Contact a tower, 2. Tell the tower who you are,
and who your provider is, 3. Tell the tower what mode it wants to communicate
with, and 4. Establish that it is in a roaming area before it passes out
of a five watt range. This procedure, called an electronic handshake, takes
approximately 45 seconds for a cell phone to complete upon initial power
up in a roaming area because neither the cell phone or cell transponder
knows where that phone is and what mode it uses when it is turned on. At
500 miles an hour, the aircraft will travel three times the range of a
cell phone's five watt transmitter before this handshaking can occur. Though
it is sometimes
- possible to connect during takeoff and landing, under
the situation that was claimed the calls were impossible. The calls from
the airplane were faked, no if's or buts.
-
- I hope I made sense, if you have questions I will respond
if possible. If I do not respond, please research this out yourself, search
the boeing site, search the DARPA site, search were you have not searched
before. Some of the information is classified and leaked by individuals,
and it is also being scoured from the net. I have all of the original documents
on my computer to safeguard against this.
-
- Please do not ignore this, because only Norad has the
flight codes for those aircraft, we did 911 to ourselves. Hitler had the
Reichstag, we have 911. If 911 proves to not be enough to make the US citizenry
set aside its rights for safety, the people who did 911 most certainly
have access to nuclear material. 911 must be exposed for what it was before
that material is used.

-
- Where he said it takes 45 seconds to handshake is totally
wrong.
-
- When you turn your phone on you can make a call within
10, the term "cellular phone" means it is able to change "cells"
or towers.
-
- Besides, wern't the phones that were used, from the plane
itself?
