UNITED STATES PATENTS
This airliner hijacking prevention system solution
is the most sophisticated solution available today. The solution consists of the
following three complementary, indispensable parts.
double-door “single person checkroom”, the only passage to the cockpit. In
this closed one-person-only checkroom a series of checks are made before
access is gained to the cockpit. The checks are made automatically, free from
the control of the aircrew. Therefore, even if terrorists are on board, they can
not gain access to the cockpit, thus preventing hijacking.
television and communication system, hidden, free from the control of the
aircrew, and with independent power supply. This system keeps informed of what
is going on in the cabin. The system transfers messages between the airliner and
the ground monitoring center through a relay satellite or special frequency
band, exposing the hijackers to the staff in the cockpit and the ground
monitoring center, and thus forming an effective deterrent to any potential
flight locus monitor free from the control of the aircrew and with independent
power supply also transfers messages between the airliner and the ground
monitoring center through a relay satellite or special frequency band. The
ground monitoring center must comply with state laws and a transnational overall
management and monitoring center must be established to bring any off-course
airliner into automatic flight through the locus monitor or bring back the
airliner to the airport through remote control. The ground monitoring center has
the final control of the airliner, making it impossible for the engineer (even
if he is a terrorist) or any other unscrupulous or crafty terrorists to make
Claims, 4 Drawing Figures
The suicide terrorist attacks on World Trade Center and Pentagon with
huge civil airliners astonish and infuriate the world. “Are we safe?” is a
question raised by the people of Hong Kong as well as USA, whose enormous
economic loss is shadowed by inner grief.
and anger are condensed into the words “Punish the terrorists!”.
hijacking!” is a paramount task of governments in the future!
and anger inspire American people to tide over difficulties with the government!
Although airports have resumed service, stricter check makes people even more
anxiety-ridden. “Are we safe?” is a persistent question. The Empire State
Building, overwhelmingly magnificent and believed to be the tallest in New York
now, is likely to be deserted by salary earners. Skyscrapers are now, expectedly
and painfully, choking the life of economy…
stock exchange is to open on Monday, the shares of insurance companies involved
will fall into disfavor. Skyscraper syndrome will also entangle real estate
shares… Arrows shot from the dark are beyond our capability to escape from.
Who is dominating the world now? The current terrorist crisis tests the
intelligence of US leaders, not America’s military power. It is but common
imagination, not Bush’s insight, to spot the harbor of terrorists and get even
with them. Airports are now under stricter control, but is there anybody who
can guarantee our safety and reassure us? How can anxiety-ridden people push
economy forward? US president Bush has a bucket of sticky problems to tackle!
How the New
York Stock Exchange will behave when it resumes operation can measure the extent
to which the world is affected by the century disaster. What is essential is how
to convince people that such a
disaster will not occur again? People expect President Bush to come out
to assure them before the Stock Exchange resumes operation:
have found a plan to prevent hijacking. We will issue, discuss and carry out the
plan! The strict and unpleasant check at airports is expected to ease after the
plan is implemented. The pain is temporary because we are powerful in our
production and technological capabilities. The
disaster will never happen again! The people of the United States and
around the world will no longer live in the shadow of terrorism! May the victims
of the disaster rest in peace. We’ll let terrorists know that human
civilization is not to be trespassed upon!”
world is waiting. And we strongly believe that the above four plans are
effective in preventing hijacking by improving the structure of the
airplane and setting up corresponding procedures. It is reported that people
working in the Empire State Building feel quite upset because of their being
“outstanding”. Acrophobia is spreading! Without plans to end
hijacking, the shares of airlines, insurance, real estate and tourism will fall
into disfavor. Fear will lead to economic turbulence and downturn. We expect
President Bush to come out with strong measures and assure people that all evils
will be conquered!
unprecedented disaster heralds the beginning of the life-and-death struggle
between the evil and the civilized community. With a sense of mission, the
inventor faxed the creative hijacking prevention device and system proposal as
well as the above background materials to Mr. Liu of USA Embassy in Hong Kong on
September 19 2001, who forwarded them to the white house and President Bush.
o’clock on September 26 2001, Mr. Liu told the inventor over the phone: “I
would like to thank you on behalf of the government of USA…” On September 27
2001, President Bush aired three safety measures for civil aviation. Mr. Bush
will expectedly take resolute actions to implement these measures and launch a
campaign to conquer the evil!
Note: In the above Proposal to President Bush on
Four Hijacking Prevention Solutions, solutions II and III are combined into
one. President Bush made some revisions and came up with the three safety
measures for civil aviation.

On October 22
2001, the Patent Bureau of China finished the international patent inspection
report concerning the application for the patent of “Measures on the
Prevention of Hijacking of Civil Airliners”. This report lists six
successful cases and the originality that a patent technique
should have. It is these six cases that set off not
only the originality of this patent but also its flawlessness!
The reference numbers of
the six cases in the Inspection Report are listed below:

International patent No.

1. Patent No. CN 85100918A
Patent owner: Mr. Yi
Ming and Mr. Shen Xinhua of Mashan Surveying and Mapping Team, Jinxian County,
Patent name: Airliners with Anti-Hijacking Function
Dec. 20 1985
The following three major technical features of this invention are to be
Walls and doors with new functions: using new materials to make the
walls and doors capable of sustaining heavy impacts and gunfire.
Two different types of “Safety cockpit” designed to prevent
hijackers from entering the cockpit, thus ensuring normal flight of the
Alarm device designed to keep people informed whether the safety door of
the cockpit is open or closed.
The first technical feature is designed
in light of the following:
Using bulletproof high-performance materials to make isolating boards.
spear-shaped and blade-shaped screws designed to fix the isolating boards and
External framework with
“metal blades” designed to fix the isolating boards and prevent hijacking.
Aluminum alloy materials shaped like knives or saw-teeth, giving the “metal
blades” extra power.
The second technical feature is designed
in light of the following:
Safety isolating walls with no doors and permanent safety cockpit.
Transit room and impermanent safety cockpit.
Transit room technique including how to enter the cabin from the cockpit
and vice versa.
The third technical feature is designed
in light of the following:
Alarm device used to keep aircrew informed whether the doors of the
cockpit and cabin are open or closed. The alarm device may consist of indicator,
flashlight and buzzer.
Spring switches designed to connect or disconnect some circuits
according as whether the safety bolts are plugged or unplugged.
Synchronized switches designed to make the alarm device automatically
operate when the airliner is started.
Obviously, the features of CN 85100918A
include the following:
Shockproof isolating walls with or
without doors, featuring bulletproof materials (unidentified yet) and
heterogeneous screws fixing isolating boards.
Over one hundred years’ development of aircraft leads to different performance
concepts of isolating-wall technique and bulletproof performance.
This patent technique is open to all aircraft manufacturers.
Permanent doorless design or entering
impermanent safety cockpit through the “transit room”.
Application for patent does not depend on failure or success of permanent
doorless design. The safety conditions of the “transit room” are monitored
through a peephole. The right of passage through the “transit room” is
subject to the perception of the aircrew, which is a time-honored concept! What
is strange is that the most recent application for patent was made in 1985, but
there weren’t the sophisticated automatic detection tools already available in
the 1970s, so that patent CN85100918A lacks the originality essential to any
patent! The inventor has further modified the design from double-wall
double-door to double-wall three-door (Figure 9). Short of automatic
detection tools, however, more doors are of no avail! A knife is enough for
the terrorists to force the aircrew to take them through the “transit room”
to the cockpit! Therefore, no one has used patent CN85100918A. The inventor is
fully aware of that and so identifies his invention as impermanent
The third patent feature of CN85100918A
is the alarm device designed to keep people informed whether the safety door of
the cockpit is open or closed.
Page 7 highlighted by the patent staff: (1) The alarm device consists
only of indicator, flashlight and buzzer. It serves to notify whether the doors
are properly closed. But the then popular infrared sensor is not used, how could
such an alarm device be sophisticated? (2) The safety lock is even more
outdated. It is intended to lock the door of the cockpit, with the key to be
kept by captain. What the terrorists need to do is steal the key (without
needing to kill the captain) and enter the cockpit. (3) The shield of the
peeping device is intended to prevent terrorists, who may look into the cockpit
through the peephole, from shooting at pilots. If the terrorists are determined
to shoot, chain switches may serve the same purpose. In addition, convex lens
widely used in stores and shops may better serve the purpose. Therefore, using
shield is like carrying coals to Newcastle!
Patent CN85100918A is
defective. The 19th-century technology was not to blame for its
inability to prevent hijacking. The scarcity of practical anti-hijacking
techniques sets off the originality of this patent technique. For example, image
identifier, identification through sound spectrum, and use of five-finger mold
instead of that of a single finger. The application of this patent system
solution will help eradicate “hijacking”!
2. Patent CN 1126686A
Patent owner: Mr.
Wang Honghua, Shangyuetang Construction Section, Zhuzhou City, Hunan Province,
Patent name: Airliner Anti-Hijacking System, January 12 1995
Requests for rights:
The application of Mr. Wang Honghua is
basically the same as No. 88103336.7 patent CN 1038434A of Mr. Zhang Hua and Mr.
Zhou Guangyuan of Beijing. This invention adopts automatic monitor to transfer
messages, but it is installed only in the airliner. The inventor treats the
airliner full of passengers as the battlefront.
The inventor designs to install the alarm
device in the cockpit, but fails to explain how the alarm device identifies
He points out that “digit-key alarm
device” is now available in China, explains how the alarm device can exactly
count the hijackers, how many cameras are needed to cover every corner of
The inventor designs to equip the plane
with auto-aim guns that are synchronous with the small video cameras,
transferring messages to the control room. His patent invention does not ensure
the safety of the hostages. Auto-aim technique is rather complicate. The
“anti-hijacking” function claimed by the inventor will fail if the hijackers
hold just one hostage or makes a smoke screen.
CN1126686A may be virtual, but it does not befit a civilized society to turn an
airliner into a battlefield. Unlike patent CN1126686A, which features
“anti-hijacking”, Mr. Zhen-man Lin patent focuses on the prevention of
hijacking, therefore his patent application is justifiable.

Requests for rights:
monitor, striker, gun barrel and gun head on the operation desk designed by the
Beijing inventor can’t prevent hijacking. They are just mechanical or shooting
devices, which can do nothing when terrorists hold any hostage. Patent
88103336.7 CN 1126686A is by no means the same as Mr. Zhen-man Lin
Having been widely used, TV monitor is
not a patent but an auxiliary method. It is not key to Mr. Zhen-man Lin patent
solution to hijacking prevention. It does not befit a civilized community to
ignore the safety of passengers and turn an airliner into a battlefield.
Therefore Mr. Zhen-man Lin application 8810336.7 is not truly valid.

HIJACKING PREVENTION SYSTEM
cockpit is isolated from the cabin to give passengers a sense of safety, but
communication must be ensured. The buttons fixed in the cabin keep the cockpit
informed of such things as oxygen shortage, fire alarm, medical accident, device
fault and any other trouble.
isolating door between the cockpit and the cabin is restricted, and the door and
its associated isolating walls are made of bulletproof materials.
voice communication system of the audio system is a one-way system from the
cockpit to the cabin, preventing the words of the hijackers from being heard.
invention warns the passengers in advance.
The key idea of the patent is that the pilots are locked in the cockpit
so that the hijackers can not communicate with the pilots. Even if the hijackers
hold any hostage, the pilots will not open the cockpit without hearing anything.
Even if the hijackers do as indicated in Fig. 4 22, the pilots may choose to
stay if the situation is not critical.
1. The US patent invention does not allow for any possible neglect of the pilots.
2. The pilots may not come even if all buttons in Fig. 4 22 are pressed.
the bulletproof wall and door of the cockpit soundproof? The hijackers
4. The pilots may rely on their unreliable perception and reasoning to decide whether to open the door of the cockpit, therefore the US patent invention is inadequate to deter hijacking.
The US patent invention in 1972 has drawn
upon the experience of the previous three patents of China but still leaves much
to be desired. By contrast, the double-door structure specified in Mr. Zhen-man
Lin patent is original, the “Single-person checkroom” is a natural evolution
of modern technology, and the five-finger mold is unprecedented. The
single-person checkroom of the double-door structure precludes the effect of
human factors and the five-finger mold makes the system flawless. The hijacking
prevention system of Mr. Zhen-man Lin is so original that the US patent
application does not affect the patent application of Mr. Zhen-man Lin.

Patent name: A Support Device Using Satellite Communication to
The inventor designed the support device
using satellite communication to prevent hijacking. The device keeps the ground
monitoring center informed of what is going on in a hijacked airliner by means
of satellite communication.
case of hijacking, the passengers or aircrew press the emergency buttons fixed
at various places in the airliner, the video camera with long or short lens
installed at an appropriate place begins to work, digitizes the information by
means of an image processing device or turns the information into FX (facsimile)
file format, and then sends the information to the ground monitoring center via
the satellite. The ground monitoring center in turn sends information via the
satellite to the camera so that the camera adjusts the foci and angles of the
long and short lens. In addition, dialogs may help to solve hijacking.
Fix several cameras at places with a good
field of vision and install a monitor in the cockpit to monitor the cabin, and
receive information from the communication satellite and transfer it to the
ground monitoring center through the support device.
Record the information of the satellite
for the use of the emergency communication device. Use the image processing
device to digitize the information or turn the information into FX (facsimile)
file format and then send it to the ground monitoring center.
Fix emergency buttons in the cockpit and
the cabin, which serve to start the support device so that the ground
monitoring center can monitor what is going on.
As the name implies, the invention is a support device to prevent
hijacking through satellite communication! The idea is good enough but not
specific yet. Its merit is the support device used for negotiation and
It is recommended in Item 3 of Mr. Zhen-man
Lin hijacking prevention system solution that, apart from using satellite
communication for negotiation and monitoring, manual piloting should be disabled while automatic
piloting enabled until the airliner touches down, thus deterring hijacking.
There lies the originality of the invention!
Satellite communication is not the patent right of application JP,A,9-036791,H04B7/15, but
instead the right of the owner and inventor of the satellite! What makes
the difference is how to use satellite communication to achieve different
purposes. Item 3 of Mr. Zhen-man Lin hijacking prevention system solution
features a detailed and original arrangement for remote control of the airliner.
Therefore we can easily come to the conclusion that application
JP,A,9-036791,H04B7/15 cannot prevent the generation of
Mr. Zhen-man Lin hijacking prevention system solution.

IV. The newest device for
precaution skyjacking and system
of Airplane Structure and Establishment of Corresponding System Program
As shown in
FIG.I-1, install “Single person checkroom” path structure to make it
impossible for terrorists to enter the cabin.
The structure of checkroom must in order to precaution against that to
bump and to pick out of..
As shown in FIG.II of the systematic
program, install independent concealed electronic monitoring device not
controllable by but visible to the aircrew. Special waveband transfer enables
ground-based monitoring center to have full control of terrorists and negotiate
with them easily.
As shown in FIG.I-3, at the four passages
of the entrances of the airliner, install remote-controlled chemical spraying
guns and appropriate obstacles to control or restrict the activities of
As shown in FIG.II, nothing is worse when
the pilot takes a hand in hijacking, but in this case “ flight locus
calibrator ” can be used to lock flight course, under the remote control of
ground-based monitoring center.
As shown in FIG.II, the ground-based
monitoring center has special plane with monitoring device, ready to fly and
trace. Or satellite relay stations may transfer monitoring messages.
Set flight discipline for the aircrew.
Add passage checkroom structure and system setting:
FIG.I-a & b. are shown, install unidirectionally
transparent bullet-proof glass door from the cabin to the passage as a
second door, so that the pilot can see the passage unidirectionally, making
hijackers conscious of someone looking at them in the dark.
As shown in FIG.VI a & b, the back
and front panels of the bullet-proof glass door are both unidirectionally
transparent, with 0.8~1-meter single person checkroom in between,
FIG.VI c. is shown a detector of raster curtain; FIG.VI d. is shown
identifying weight; FIG.VI e. is shown a detector of password card;
FIG.VI h. is shown a detector of Five-finger mold test; FIG.VI i. is
shown a detector of Image test; FIG.VI
j. is shown a detector of human body infrared; FIG.VI k. is shown a launcher of
special beams; FIG.VI l. is shown a
detector of voice recognition; they will be automatically identifying weight,
password card, fingerprint , image and voice test.
As shown in FIG.II, the front and back
panels are closed under the double control of closing instructions of airplane
in flight status and ground-based monitoring center, meanwhile turning on
the automatic identifier.
FIG.II. is shown, aircrew must get
permission via communication and password card instruction to open the first
door and enter the checkroom, and the automatic identifier, after sensing only
one person in the checkroom, closes the first door and begins to check.
As shown in FIG.III, after the automatic
identifier checks single person only and makes ID identification,
the cabin, on being notified of the ID of the approaching person, decides
whether to open the second door. The first door will not open until the second
door closes, thus preventing hijackers from swarming in.
Persons in the cabin will be documented by the captain and monitoring
center respectively when the automatic identifier is started. There must be at
least one engineer in the cabin, otherwise no person can pass the checkroom,
except in non-flight status of the plane or by
If any person in the cabin wants to leave
the cabin during flight, a simple password card can be used to open the second
door and enter the checkroom, and the automatic identifier in the checkroom
instructs to close the second door and begins to check. The first door can be
opened only after the check.
The automatic identifier sets the number
of persons in the cabin and decides that at least one engineer must stay in the
cabin during flight.
Problems and solutions:
The automatic identifier
restricts the number of persons in the checkroom, making it impossible for
hijackers to enter the checkroom together with the aircrew. A hijacker may only
enter under disguise, but the automatic identifier may have
identification combinations, such as the weight, fingerprint and palm print and
voice. The unidirectionally transparent glass door fully exposes hijackers, but
it is necessary to equip back-view mirror for the engineer or formulate review
system to increase the weight of manual check.
Why use the
five-finger mold? Because a single finger may be cut, but if the whole hand is
cut, it will be impractical and unnecessary to use modern technology to make a
frozen cut hand resume its original appearance in the short time and limited
space. This makes the system flawless.
Even if the engineer and aircrew are
hijackers, who can freely pass the Single person checkroom, they are
restricted by II.(3) Lock flight course by means of flight locus calibrator
Independent concealed electronic monitoring device:
The historic disaster of World Trade Center
shows how defective the designs of airplanes are: the hijackers shut down all
communications facilities so that their identities remain a mystery. The black
box cannot provide real-time on-site video and audio recordings, making it
almost impossible to find and punish those behind the terrorist acts.
As shown in FIG.I-4,
the airplanes are not equipped with independent concealed video and audio
electronic monitoring equipment and real-time transfer and storage equipment,
which (if any) cannot be controlled by the aircrew. This is ridiculous today,
when technology is so sophisticated and the space is studded with satellites. No
doubt, the US aviation security bureau cannot pass the buck.
Therefore, it is imperative that independent concealed electronic
monitoring device should become a standard device of an airliner. Some people
may claim that their privacy is encroached upon, but the monitoring on the
channel is within the permitted range.
And so the independent concealed electronic monitoring device may
somewhat deter potential hijackers.
Lock flight course by means of flight locus calibrator:
shown in FIG.II, in case the flight locus deviates from the preset course, the
calibrator (FIG.I-6) will surely use the alarm functions of channel feedback
center of the electronic monitoring device.
With flight locus
calibrator, the ground-based monitoring center may switch manual steering
over to remote-controlled automatic/ semiautomatic steering (not beyond the
present technology) when the engineer loses his right to act.
is advisable to draw upon the high-air remote control technology of air scouts.
The security of a hijacked plane may somewhat be affected by geographical and
atmospheric conditions, but “remote control” can bring the hijacked plane to
“an automatic flight status” and thus absolutely prevent the plane from
suicide attack on downtown areas or landmark buildings. For example, the plane
can be made to safely rise and fly away from the downtown area and enter into
d. Confidentiality of remote control information is no problem in today’s digitized age.
(4) The ground-based monitoring center has special plane with monitoring device, ready to fly and trace. The ground-based special remote-controlled plane prevents an accident plane from flying out of the direction radius.
Set flight discipline for the aircrew:
It is necessary to strictly comply with the discipline set by the
structure and program of the channel calibration room so as to preclude
Make the engineer more capable of tackling emergencies mainly with
portable non-fatal chemical weapons.
The Measure Plan of this patent centers on
Various combinations of available classifiable
techniques are used in the Measure Plan;
The Measure Plan is quite comprehensible. Except
the remote-controlled which are
encrypted, all the rest is open to the public,
thus serving as an effective deterrent to hijackers;
Even though the above Measure Plan leaves much
to be certified and improved, it comes
right to the point if considered from the
perspective of the global economy;
It is likely for the Americans to accept the
plan, because they have their own thoughts and
judgements! They will regain confidence in
safety and overcome their fears incurred by the disastrous attacks. The global
economical order is soon to return to normal!

system transfers messages between the airliner and the ground monitoring center
through a relay satellite or special frequency band, and continuously monitors

from deteriorating and keep records of the doings of the terrorist group;
Remote control of the plane by the ground monitoring center is affected
by poor coverage in blind spots formed due to the effect of ionosphere or due
the geographical location itself. Therefore standby remote-control facilities
are necessary in order to ensure the safety of passengers;

Uprooting hijacking, striking terrorism worldwide and defeating the evil by enlightened means manifest the intelligence of the civilized human community.
