HEAVILY GUARDED PLACES ON EARTH

However, some places are so restricted and guarded that getting in or out is impossible. So, keep your head high as we look at Earth's most heavily guarded places. Some of these places are:

Information Station.

In Butler County, Pennsylvania, an unassuming road is one of America's most secure storage facilities. Until now, very few people outside of Pennsylvania even knew this place existed. It's enigmatically called The Underground. It is run by the data management company Iron Mountain.

There are no signs on the road to show you where it is, and from the front door alone, You will forgive yourself for assuming there's nothing interesting here. However, 220 feet below the ground in a massive 1,200-acre former limestone mine is a small underground city with its own fire brigade, security, speed limits, traffic lights, street names, and sidewalks. This isn't just any old storage facility. It houses everything from government and corporate documents to famous musicians' master recordings.

Charles Darwin's will is even kept in there. As such, the millions of priceless items require the utmost care and security to ensure everything runs smoothly, and that means some 2,000 people are working there every day.

As well as physical things, though, Iron Mountain also safeguards important digital data; multiple copies of the same data are stored in separate places.

So, if part of the center goes down, customer information is still accessible

because it's stored elsewhere. But this requires a butt-ton of power. The Underground has a cooling system, drawing water from a 35-acre flooded mine.

The facility also has a waterproof roof to prevent leaks, and it's in a low-risk earthquake zone. A three-ton steel gate and 24/7 armed guards ensured no unwanted visitors could enter. This place sounds incredible.

Protected Plane

Air Force 1 is the code name given to any aircraft carrying the President of the United States of America. you might have flown business class, some of you might have even flown first class, but you've never flown President Class. This plane is decked out with a private residence, meeting rooms, medical facilities, and all the Secret Service agents you can imagine, but absolutely no weapons. Air Force 1 has so many built-in defense systems

it doesn't really need them. For a start, it has multiple infrared countermeasures capable of redirecting missile threats away from it. Many missiles are designed to follow heat, but Air Force 1 has special jammers that radiate an altered infrared light.

This interferes with the missile sensors, causing them to lose sight of the heat produced by the aircraft engines. it also has deployable flares that burn super hot and can misguide any threat. The internal communication systems are encrypted, meaning any calls, radio communications, or computer connections can safely reach whoever they need without fear of interception. And if the superplane has to fly over a dangerous area, scramblers jam nearby aircraft radars, keeping the President's location totally anonymous. It has enough supplies to stay aerial for two to three days.

Theoretically, because of an in-air refueling connection, it doesn't ever actually have to land. It can just keep flying and get a top-up from a specially designed-refueling aircraft when necessary.

Diligent Defense.

The thing I love most about America is that they're innovators. The US Department of Defense headquarters in Arlington County, Virginia, with a steadfast commitment to protecting the nation and its interests, implemented diligent defense measures at this facility, which are unparalleled. Everyone entering the building must undergo a thorough screening process to ensure safety and security within its walls. This rigorous procedure leaves no stone unturned in identifying potential threats and ensuring that only authorized personnel gain access to sensitive areas.

Anyone entering the building undergoes a thorough screening, and inside photography is banned to protect confidentiality.

Any deliveries to the site must first go through a nearby 250,000-square-foot remote facility, which processes 250 trucks daily. Once a vehicle is cleared to enter the facility, it undergoes a thorough inspection, including checking the undercarriage with mirrors and having a canine squad search for explosives. Drivers must also pass through a metal detector before opening any cargo doors. All materials are x-rayed and subjected to product-specific inspections. Then, and only then, can they be transported into the Pentagon.

Perhaps the most impressive feature of the Pentagon itself is the blast-resistant windows along the E and A Rings of Wedge 1. Each window is one and a half inches thick and weighs a ton. During 9/11, a hijacked plane was flown directly into the Pentagon

and these windows saved the lives of thousands of people. It just goes to show how important these defensive measures are.
