I believe that many friends are the same as Xiaobian, every time they take a plane, they can't help but complain about "security check is troublesome"
After all, every time you have to queue up a long line, but also to turn the suitcase over a "bottom to the sky"; the security check is more strict airports, but also to untie the belt, take off the shoes to check, some netizens said that they have also encountered the request to take off the socks...
Although we understand that the strict security check is to ensure the safety of everyone's travel, why are there special inspections such as undoing the belt and taking off the shoes? I believe that after reading the following content, you will have more understanding and patience for the security check.
Why should metal items be inspected separately?
Why didn't the security inspectors let go of even a small coin? Because some people with ulterior motives will use small coins to make a fuss.
Xiaobian once read a report that an airport security inspector once seized a coin lighter. This lighter looks no different from a coin on the surface, and it is easy to get through the customs, and once used on the plane, it may threaten the safety of passengers' lives and property.
Because of this, even if there is only a one in ten thousand chance, the security inspector will ask the passenger to remove all metal objects on the body separately and check them out, and intercept the dangerous goods outside the security gate.
And the X-ray machine used for security inspection is limited, metal things will be obscured inside, if the number of coins is too large, the security inspector can not determine whether there are dangerous items hidden under a pile of coins.
There is another reason for requiring passengers to remove metal objects: if passengers have metal objects on them, they will call the police when passing through the security gate, and the security inspectors will manually review them with metal detectors. This wastes time and affects the overall efficiency of security screening.
Why should the laptop be taken out and checked separately?
This is mainly due to the complex internal structure of the notebook computer, and the color of the image presented when the X-ray machine is examined will be darker. In contrast, the color of the image presented by other items that do not belong to the metal category will be relatively light.
Therefore, when the passenger's luggage bag carries a lot of different types of items, including computers or other items, before the security check, if the computer is not taken out, the image made by the computer will affect the security inspector's judgment of the image.
Therefore, even after the X-ray machine inspection, the security inspector will still let the passenger take out the computer and check it separately. Therefore, in order to improve the pass rate of security checks and save everyone's valuable time, remember to take out laptops, iPads, charging treasures or other electronic devices in advance
Why untie my belt and take off my shoes?
Because the waistband is metal, the location of the belt is where it is easy to hide prohibited items, and it is also a place where more contraband is found.
The metal belt buckle triggers the alarm of the metal detector, so after upgrading the security level, the belt removal rate and the shoe removal rate will be required.
Some airports also require separate inspections of passengers' shoes. Some travelers may wonder why they have to take off their shoes.
You may not know that after 9/11 in the United States, another terrorist intended to detonate shoes containing explosives on a plane. There was no request at the airport to take off the shoes for inspection, so the terrorist boarded the plane.
Fortunately, after he lit his shoelaces, he was subdued by the flight attendant and the passengers. Since then, many airports have begun to require passengers to take off their shoes for inspection.
It should be known that shoes are also a place where more contraband is seized, and the common ones are lighters, knives, drugs, etc., so it is also necessary to carefully check the shoes.
Security screening levels vary from airport to airport, and the airport will also adjust the security screening procedures according to whether there is a major event in the local area. When you go through the security check, if you encounter the security inspector who intercepts you because the volume of the cosmetic container does not meet the regulations, or requires you to take out the metal items for separate inspection, do not arbitrarily think that it is intentional to embarrass you, take the initiative to cooperate with their work, and are also responsible for their own safety!
