Aircraft Parts and the Precautionary Principle
Impossible to Prove a Falsehood True:
Aircraft Parts as a Clue to their Identity
by George Nelson
Colonel, USAF (ret.)
The precautionary principle is based on the fact it is
impossible to prove a false claim. Failure to prove a claim does not
automatically make it false, but caution is called for, especially in
the case of a world-changing event like the alleged terror attacks of
September 11, 2001. The Bush administration has provided no public
evidence to support its claim that the terror attacks were the work of
Muslim extremists or even that the aircraft that struck their
respective targets on September 11 were as advertised. As I will show
below, it would be a simple matter to confirm that they were - if they
were. Until such proof is forthcoming, the opposite claim must be kept
in mind as a precaution against rushing to judgment: the 911 hijackings
were part of a black operation carried out with the cooperation of
elements in our government.

July 1965 I had just been commissioned as a Second Lieutenant in the U.
S. Air Force after taking a solemn oath that I would protect and defend
the Constitution against all enemies, foreign and domestic, and that I
would bear true faith and allegiance to the same. I took that oath very
seriously. It was my constant companion throughout a thirty-year
military career in the field of aircraft maintenance.
As an additional duty, aircraft maintenance officers are
occasionally tasked as members of aircraft accident investigation
boards and my personal experience was no exception. In 1989 I graduated
from the Aircraft Mishap Investigation Course at the Institute of
Safety and Systems Management at the University of Southern California.
In addition to my direct participation as an aircraft accident
investigator, I reviewed countless aircraft accident investigation
reports for thoroughness and comprehensive conclusions for the
Inspector General, HQ Pacific Air Forces during the height of the
Vietnam conflict.
In all my years of direct and indirect participation, I never
witnessed nor even heard of an aircraft loss, where the wreckage was
accessible, that prevented investigators from finding enough hard
evidence to positively identify the make, model, and specific
registration number of the aircraft — and in most cases the precise
cause of the accident. This is because every military and civilian
passenger-carrying aircraft have many parts that are identified for
safety of flight. That is, if any of the parts were to fail at any time
during a flight, the failure would likely result in the catastrophic
loss of aircraft and passengers. Consequently, these parts are
individually controlled by a distinctive serial number and tracked by a
records section of the maintenance operation and by another section
called plans and scheduling.
Following a certain number of flying hours or, in the case of
landing gears, a certain number of takeoff-and-landing cycles, these
critical parts are required to be changed, overhauled or inspected by
specialist mechanics. When these parts are installed, their serial
numbers are married to the aircraft registration numbers in the
aircraft records and the plans and scheduling section will notify
maintenance specialists when the parts must be replaced. If the parts
are not replaced within specified time or cycle limits, the airplane
will normally be grounded until the maintenance action is completed.
Most of these time-change parts, whether hydraulic flight surface
actuators , pumps, landing gears, engines or engine components, are
virtually indestructible. It would be impossible for an ordinary fire
resulting from an airplane crash to destroy or obliterate all of those
critical time-change parts or their serial numbers. I repeat,
impossible.
Considering the catastrophic incidents of September 11 2001,
certain troubling but irrefutable conclusions must be drawn from the
known facts. I get no personal pleasure or satisfaction from reporting
my own assessment of these facts.
United Airlines Flight 93
This flight was reported by the federal government to be a
Boeing 757 aircraft, registration number N591UA, carrying 45 persons,
including four Arab hijackers who had taken control of the aircraft,
crashing the plane in a Pennsylvania farm field.
Aerial photos of the alleged crash site were made available to
the general public. They show a significant hole in the ground, but
private investigators were not allowed to come anywhere near the crash
site. If an aircraft crash caused the hole in the ground, there would
have literally hundreds of serially-controlled time-change parts within
the hole that would have proved beyond any shadow of doubt the precise
tail-number or identity of the aircraft. However, the government has
not produced any hard evidence that would prove beyond a doubt that the
specifically alleged aircraft crashed at that site. On the contrary, it
has been reported that the aircraft, registry number N591UA, is still
in operation.
American Airlines Flight 11
This flight was reported by the government to be a Boeing 767,
registration number N334AA, carrying 92 people, including five Arabs
who had hijacked the plane. This plane was reported to have crashed
into the north tower of the WTC complex of buildings.
Again, the government would have no trouble proving its case
if only a few of the hundreds of serially controlled parts had been
collected to positively identify the aircraft. A Boeing 767 landing
gear or just one engine would have been easy to find and identify.
United Airlines Flight 175
This flight was reported to be a Boeing 767, registration
number N612UA, carrying 65 people, including the crew and five
hijackers. It reportedly flew into the south tower of the WTC.
Once more, the government has yet to produce one serially
controlled part from the crash site that would have dispelled any
questions as to the identity of the specific airplane.
American Airlines Flight 77
This was reported to be a Boeing 757, registration number
N644AA, carrying 64 people, including the flight crew and five
hijackers. This aircraft, with a 125-foot wingspan, was reported to
have crashed into the Pentagon, leaving an entry hole no more than 65
feet wide.
Following cool-down of the resulting fire, this crash site
would have been very easy to collect enough time-change equipment
within 15 minutes to positively identify the aircraft registry. There
was apparently some aerospace type of equipment found at the site but
no attempt was made to produce serial numbers or to identify the
specific parts found. Some of the equipment removed from the building
was actually hidden from public view.
Conclusion
The government alleges that four wide-body airliners crashed
on the morning of September 11 2001, resulting in the deaths of more
than 3,000 human beings, yet not one piece of hard aircraft evidence
has been produced in an attempt to positively identify any of the four
aircraft. On the contrary, it seems only that all potential evidence
was deliberately kept hidden from public view. The hard evidence would
have included hundreds of critical time-change aircraft items, plus
security videotapes that were confiscated by the FBI immediately
following each tragic episode.
With all the evidence readily available at the Pentagon crash
site, any unbiased rational investigator could only conclude that a
Boeing 757 did not fly into the Pentagon as alleged. Similarly, with
all the evidence available at the Pennsylvania crash site, it was most
doubtful that a passenger airliner caused the obvious hole in the
ground and certainly not the Boeing 757 as alleged. Regarding the
planes that allegedly flew into the WTC towers, it is only just
possible that heavy aircraft were involved in each incident, but no
evidence has been produced that would add credence to the government’s
theoretical version of what actually caused the total destruction of
the buildings, let alone proving the identity of the aircraft. That is
the problem with the government’s 911 story. It is time to apply the
precautionary principle.
As painful and heartbreaking as was the loss of innocent lives
and the lingering health problems of thousands more, a most troublesome
and nightmarish probability remains that so many Americans appear to be
involved in the most heinous conspiracy in our country’s history.
Footnote: It will soon be five years since the tragic
events of 9/11/01 unfolded, and still the general public has seen no
physical evidence that should have been collected at each of the four
crash sites, (a routine requirement during mandatory investigations of
each and every major aircraft crash.) The National Transportation
Safety Board has announced on its website that responsibility for the
investigations and reports have been assigned to the Federal Bureau of
Investigation, but there is no indication that mandatory investigations
were ever conducted or that the reports of any investigations have been
written.
