Although there is not enough evidence to conclude whether these flying objects are from another planet, some videos and images of UFOs have been confirmed by the US military to be real. This information not only interests the community interested in extraterrestrial life, but also raises questions about the information the Pentagon holds about UFOs. The US has repeatedly recorded reports of mysterious flying objects appearing in military airspace. (Photo: CNN) Next June, the office of the director of the National Intelligence Service and other agencies are expected to submit previously unpublished UFO reports to the US Congress. According to CNN’s source, the US will soon announce how the Pentagon handles information about unidentified flying object encounters. What are UFOs? UFO is a flying object whose shape and movement are completely different from all types of aircraft that man-made. Many theories suggest that they are technological products from extraterrestrials, but so far the true nature of UFOs remains a mystery. Last month, the Pentagon officially confirmed that some images and videos recorded by the US Navy were genuine. In 2017, a former US Navy pilot claimed to have seen an unidentified flying object in 2004. This person said the object believed to be a UFO had a very strange way of moving. “ When I got close, it quickly accelerated south and disappeared in less than 2 seconds “, said retired pilot David Fravor. Video taken by US Navy soldiers in 2019 shows flashing triangular objects moving through clouds. Several other images also provided by the Navy show three spherical metal-like objects flying in the sky. In April 2020, the Pentagon released three videos from infrared cameras showing flying objects moving at very fast speeds in the air. According to Pentagon spokesman Sue Gough, the Navy acknowledged the veracity of the videos released in 2019 months before they were released “to clear up public doubt as to whether the videos were released in 2019. Is it real or not?” UFO is a flying object whose shape and movement are completely different from all types of aircraft that man-made. (Photo: The New Yorker) Are aliens real? The US government’s recognition of UFOs as real leads to the question: Are aliens real? Luis Elizondo, former director of the Department of Defense (DoD) research program, once said: “ There is compelling evidence that we may not be alone (in the universe). “. “ These planes – we call them airplanes for now – have features that cannot be found in American equipment or in any foreign technology that we know of. “, said Mr. Elizondo. But whether UFOs are alien vehicles or a human product, they are still of interest to the US government. Because the problem of handling unidentified flying object information is also related to ensuring that all potential risks to the national security of the United States are taken seriously. Whether that threat comes from space or not. “ Whether it’s weather balloons, green aliens or something else – we can’t ask our pilots to put their lives unnecessarily at risk. “. Rachel Cohen, spokeswoman for Democratic Senator of Virginia Mark Warner, speaking about UFOs in 2019. UFOs have features that cannot be found in American equipment or in any foreign technology. (Photo: CBS News) What’s in the new UFO report? While UFO experts applaud the recent moves by the US government, many remain skeptical of the content of the upcoming unidentified flying object reports. This suspicion stems from the Pentagon’s indifference to previous UFO reports. Many times, the community interested in this issue received only the vague answer that the appearance of flying objects was “unexplainable”. Therefore, they believe that the new report will not provide complete and comprehensive information about UFOs. Last month, Mr. Elizondo said that the “best case scenario” is that the new report only outlines the issue and offers the promise of “another, more detailed report” in the future. “ Unfortunately, what we don’t know outweighs what we do know. But the good news is that we’re finally getting serious about it “, said Mr. Elizondo. The Pentagon has set up a panel to explore the “nature and origin of unidentified flying objects”. (Image: Getty Images) The Pentagon says it has conducted research on audio recordings of unidentified flying object encounters as part of a secret program deployed at the request of a former Democratic senator. owner Harry Reid in Nevada. The program began in 2007 and ended in 2012 as the US Department of Defense assessed that funding for more important projects should be prioritized. Following the program, the Pentagon established a topic to explore “the nature and origin of unidentified flying objects” by 2020, according to the US Department of Defense. Topics include videos of UFOs recognized last month. Up to now, the truth about UFOs, or the question of whether or not aliens exist, remains a secret from the public.

USS San Francisco was one of the first Los Angeles-class nuclear attack submarines of the United States, built in 1972 and commissioned on April 24, 1981. It is also the quietest submarine in the US Navy. The bow part of the ship was crushed after hitting a mountain. Photo: National Interest USS San Francisco has a displacement of 6,900 tons when submerged, 110 meters long and 10 meters wide. The train is equipped with a General Electric PWR S6G nuclear reactor with a capacity of 35,000 horsepower, helping it to move at a maximum speed of 61km / h. According to the National Interest, the accident occurred with the Los Angeles-class submarine USS San Francisco (SSN-711), on January 8, 2005. At the time of the collision, the ship was near Guam conducting training and preparing to sail to Australia. At that time, the ship was diving at a depth of 160m and moving at a great speed, more than 48km / h. The impact was very strong. The sailors present in the dining room were thrown into the air. In a 60-minute interview, Brian Barnes, a submariner, recalled: “I just saw people lying everywhere. Glass was broken, dishes were splattered, sailors groaned from their injuries, screamed.” The bow of the USS San Francisco was severely damaged, 30m of the front hull was flattened and exposed to the sea. Water flooded the submarine. The urgent task at that time was to urgently pump compressed air into the ballast tanks of the submarine to help the ship float to the surface. The USS San Francisco has a total of 127 crew members. The collision left 98 people injured and many of them were unable to continue operating the ship. Sailor Joseph Allen Ashley was wounded in the head and later died. Another sailor broke both arms but still managed to open the submarine’s air valve to fill the ballast tanks. Danny Hager, who monitors the submarine’s depth gauge, had a terrifying experience after the valves were opened. “I told everyone that the ship was at a depth of 160m. And I kept waiting, 5 seconds, 10 seconds passed and so on I don’t know how much longer, the ship was still at a depth of 160m. The atmosphere is very calm because everyone is waiting for me to announce that we are preparing to come up.” The problem was that the ballast tanks at the front were broken in the collision. The air escapes to the outside. 60 seconds passed and the ship remained unchanged in depth. Fortunately, the aft part of the submarine began to point upwards as the ballast tanks at the aft were filled with compressed air. Danny Hager now feels less worried: “It feels really relieved when I announce the ship has risen to a depth of more than 152m”. Finally, the USS San Francisco also surfaced, but the journey home is still quite far. Fortunately, the nuclear reactor was not damaged in the impact. The crew steered the ship back at a speed of 16km/h and so to return to Guam, it took the ship 52 hours. Unexpected causes Despite its immense firepower and nuclear propulsion, the USS San Francisco, like all submarines, relies on charts providing data on the topography of the seabed. After the investigation, the US Navy found that the submarine used old charts that did not mention the submarine mountain range in the area of ​​​​the ship’s operation. Meanwhile, other maps warn about this mountain range. The charts used by the crew of San Francisco were provided by the Defense Mapping Agency in 1989. By 2008, a study by the University of Massachusetts showed that images obtained from the Landsat satellite showed An underground mountain range more than 30m above the seabed in the area. However, the US Navy did not update this information to the chart. During the repair, the bow of the USS San Francisco was removed and replaced with the bow of the submarine USS Honolulu, which was about to be decommissioned. USS San Francisco rejoined the fleet in 2009 and served for another seven years. It was later converted into a training submarine. Ship commander Kevin Mooney was reprimanded for this unfortunate accident. Several sailors received medals for their brave actions when the ship was in distress. Only the sailor who died Ashley is inscribed at the Navy Memorial in Washington DC So how could the ship survive the high-speed crash into the underground mountains? In 1963, after the sinking of the submarine USS Thresher, the US Navy established the SUBSAFE program. The goal of this program is to ensure that the hull will remain pressurized in the event of an accident and that it can float. This program makes keeping nuclear reactors safe and making them recover from accidents a top priority. If the ship can surface and the nuclear reactor continues to operate, the crew will have a good chance of survival. USS San Francisco has ensured those conditions. Thus, the fact that the USS San Francisco can “survive the accident” is the result of the dedication and relentless research efforts of the US submarine force.

Even the first pilot to land on a warship was carrying safety gear: Eugene Ely, attempting to land on the deck of the armored cruiser USS Pennsylvania in 1911, was flying Curtiss Pusher, wearing a leather soccer helmet, eyeglasses, and a makeshift life jacket made of bicycle tubes. The probability of the pilot being forced to end the mission with a parachute launch from the cockpit is very small – it happened exactly 1.33 times per 100,000 flight hours, according to the US Navy. But naval aviation officers still carry equipment for such a scenario. “Most equipment is used only in emergencies,” said Lt. Luke “Oslo” DeLisio, a flight officer from the 106th Strike Squadron. Inside, the pilot wears a cotton bra. In the event of a fire in the cockpit, the cotton will not melt and stick to the skin like nylon or polyester. In terms of underwear, the pilots wore a one-piece CWU 27 / P Nomex suit. Developed by the DuPont company in the 1960s, Nomex is a synthetic flame retardant that can withstand heat and flash (a form of electrical discharge) up to 400 degrees Celsius. When the Nomex suit encounters high temperatures, the fibers Its thickens and carbonizes, absorbing heat. The standard color of the CWU 27 / P is sage green, but the American pilots who served in the Persian Gulf area and nearby wore desert brown. The flight suit is a one-piece, zippered front jumpsuit design to ensure limited exposure to fire. DeLisio says it’s a comfortable fit. “We call it” pocket “. No need, this thing is ready-made, just stick the stickers in and go. It’s almost like wearing your pajamas to work. ” Equipped with a velcro and eight pockets (including a zippered arm pocket with a separate cap for holding the pen), the flight suit is standard work attire both on and off the plane. “I usually keep my wallet and canvas hat in my leg pocket,” says DeLisio that most other bags are difficult to reach while flying. Other pilots use arm pockets to carry their mission cards and a pen or two. American pilots are also equipped with long, fireproof GS / FRP-2 gloves. US Navy Lieutenant Alexander Klapka carries all the equipment an F-18 pilot wears. Why are most pilots not wearing black shoes? The carrier deck is like a construction site – there is always a risk of something falling or rolling over the pilot’s feet while he is on deck. The pilot wears military-issued or separately purchased leather boots (but approved by the US Navy) with steel toes protected. Integrated steel reinforcement protects the pilot’s toes when parachuting from the plane. High ankle support is a must for rough grounding. While a sports parachute slows a person down to about 5m / sec, a person falls in a faster military parachute – around 7.3m / sec. Each pilot has a preference for footwear, but DeLisio wears Bellville flying shoes that are issued by the naval air force. He says he has worn multiple pairs, but adds one difference: “My shoes are always brown.” Navy pilots are in constant debate about the color of the shoe – black or brown. “ A guy in black shoes is usually a guy working on deck, ” says DeLisio. Pilots tend to wear brown shoes, but some people still wear black shoes. Top Gun and Blue Angels show crew pilots still wear black boots, but brown stubbles are more common among fighter pilots. Outside of the flight suit, a pilot wears a CSU-15A / P. G-suit, which, as the name suggests, has airbags that compress the pilot’s legs and abdomen, helping to retain blood in the brain. of the pilot in high-speed maneuvers. Pilots can withstand six times the force of gravity without wearing a G suit, but the CSU-15A / P suit allows a typical F / A-18 fighter pilot to perform maneuvers. with a gravitational acceleration up to 7.6 G before losing consciousness due to this force.

There is a copy of the book “The American Practical Navigator” by Nathaniel Bowditch, first published in 1802 on each of the US Navy ships.

This is considered an encyclopedia about navigation, filled with data on the longitude and latitude of many places, from Bugio lighthouse in Lisbon, Portugal, to Kannonzaki lighthouse in Yokosuka, Japan.

The book provides detailed instructions on how to use a hexagonal glass to measure a ship’s current position by observing the Sun, Moon, stars, and horizon. However, the presence of this book on board is only a ritual, as the US Navy has long been accustomed to using electronic charts based on GPS, Nikkei Asia said.

But the threat of electronic warfare from rivals like China, forcing the US Navy to consider the possibility of reusing the supposedly outdated navigation system, in preparation for the GPS system scenario prepares the enemy. disable.

Combining ancient and modern

In August 2020, the USS Patriot, an Avenger-class minesweeper of the US Navy stationed at the port of Sasebo, Japan, crossed a distance of 1,700 km into the western seas solely by astronomical positioning.

Every afternoon, sailors would take a hexagonal glass, a centuries-old measuring instrument, to measure the angle of the Sun at its highest point in the day. The data will be fed into a computer program called the astronomical estimation system of latitude and longitude, also known as STELIA.

Sailors also observed the angular distances between the horizon and the Moon, the planets and the stars to calculate longitude and latitude. On the command tower, a navigation team consisting of the captain, subordinate officer and the pilot uses manual measurement data to control the ship.

Astronomical navigation has disappeared from the US Naval Academy curriculum since 2006, because it was deemed obsolete. But since 2015, the technique has been reintroduced into the program, to teach students how to measure and apply math to locate.

The re-teaching of astronomical navigation has been prompted by the acknowledgment that the US armed forces are increasingly dependent on digital systems. An attack on the GPS system that the US military is relying on, could limit the capabilities of the world’s most powerful military.

This concern becomes even more urgent as China invests heavily in electronic warfare and cyberspace.

Peter Singer, an expert at the Center for New Security of America, said the battle to kick off the next big war will take place in silence. In other words, it’s the war in cyberspace.

If digital communication was to be attacked, the US Navy would have to rely on the natural world, ears and eyes to survive, which is the reason for the return of the hexagonal glasses.

Learn how to position birds

Mr. Singer said that in addition to the astronomical navigation system dating back to the 18th century, the US should study another smarter navigation system for navigating ships, or guided missiles without relying on GPS. , similar to how birds migrate annually.

“The way they (the birds) move is not memorizing, it’s how they perceive Earth’s magnetic field. Some insects can do this too, so in-depth research is needed to develop a digital version of how birds move, ”says Singer.

The U.S. Defense Advanced Projects Research Agency (DARPA) is pursuing the Adaptive Navigation System project, a navigation technique that can work in buildings, under dense canopy, under water and ground. This system is said to be superior to GPS.

In February, a team of scientists released a report stating that birds may have global GPS systems.

“The precise navigation of these little birds is amazing, as they move alone across the sea, across the vast desert and through extreme weather conditions is one of the long-standing mysteries. behavioral biology “, a British scientist wrote on the World Economic Forum.

This may be the answer the US military is looking for in its defense mission against electronic warfare operations by China and other adversaries.

Billy Fabian, senior analyst at data analytics firm Govini, said preparing for the scenario of digital communication disruption is crucial, given the potential confrontation with China.
