The device and defence system planned for the protection of airplanes against terrorists and hijackers is described with the following characteristics: It's complex and coherent, and it consists of an extremely strong and hard ceiling cover which is made of plastic or kevlar strengthened by carbon-fibre, and this false ceiling is used in the corridors between the pilot and passenger cabins and in other relevant areas and rooms that has got a great importance in the defence system, and there are hidden launchers - for firing sleeping bullets which cause unconciousness or a paralysed state - placed on mountings above the false ceiling and they can be moved synchronised from the cockpit with hidden mini cameras by electromotors in every direction which are camouflaged as relieves or decorations, and they are connected with the pilot cabin by multy-plug cables or wireless remote transmitters where a security officer is constantly checking the central computer and its monitors to be able to divert any danger in time with the help of the hidden mini cameras and launchers if a terrorist or hijacker attack takes place on the board. |
