Hundreds of millions of people are traveling all throughout the world via plane; also hundred millions have their luggage pieces to be screened for airport security purposes – screened for explosives and other dangerous paraphernalia.
Strict airport security measures are obliged to ensure every passenger’s safe destination arrival. Yet how does it assure – the airport security inside and out?

The outside parameters have to be the first line of defense in airport security. Airport fences/barriers/walls are difficult enough to climb and completely enclose the entire airport property. If someone cuts through the barricade then they may not pass through the airport security patrols regularly scanning the extremity areas – the most sensitive zones most especially: terminals, baggage handling amenities, even fuel depots. These sites are additionally secured with more fencing and check-points. Either a guard-station or a surveillance-camera system also monitors all access-entryways. If so an infiltration threat is detected then large concrete barriers designed to block even the largest of vehicles are deployed for second blockade. During these times the parking-baggage-loading zones are kept-clear of traffic. It is also expected that no one is further allowed to park anywhere near the terminal.

Inside, airport security targets all individuals that can go about anywhere within the premises – most especially travelers. The identities of each traveler are confirmed by checking authentic ID or passport or drivers’ license photos. Biometrics is also used to measure personal identifications which include use of sophisticated computer systems to authenticate a person’s profile gathered from finger-prints checking, retinal scan, and facial patterning/recognition. This procedure easily detects if a person matches any government lists of wanted criminals, delinquency suspects, or terrorists. Another airport security measure is the use of PI (pulse-induction)-based (high-tech multi-zone) metal-detectors and dual-energy x-ray systems through which both passengers and all luggage items are scanned for dangerous ammunitions. Many airports also employ larger CT-scanners that calculate the mass/density of each bag item determining if it falls within the range of a potentially dangerous material. CT-scanning though checks only the bags that are flagged ‘suspicious’ showing-up anomalously at reservation or check-ins. Many airports also use (desktop/handheld/walk-through) chemical-sniffers. The attendant swipes a cloth over a suspicious electronic-device and places the cloth on the sniffer which analyzes and warns for traces of chemicals used to make explosives, also detecting narcotics.

Additionally, the operators of all these technology are also trained to visually perceive suspicious items apart from the obvious ones like guns or knives. These personnel are very much familiar with equipments that could be components of an IED (Improvised Explosive Devices). And about K-9 Units? – These trained dogs best odor-detects drugs and bombs incredibly fast and accurate. Flight and airport security attendants also check for potentially hazardous items even those hand-carry common stuffs. Airport security in other countries even involves air-marshals – classified federal-agents disguised as regular passengers with a reserved authority and secret assignment.
With all these airport security measures inside out, there is better assurance that you will have a safe and secure trip.
