Top 10 Creepiest UFO Mysteries

Melbourne, Australia


In the spring of 1966, around 200 people witnessed what remains Australia’s most notable UFO encounter. Staff and students of Westall High School were on recess when they saw a silverish-grey cigar- or disc-shaped object silently performing strange maneuvers overhead. The craft, followed by about five light aircraft, eventually descended into a nearby field known as “The Grange Reserve.” Some students raced to the site, and according to several witnesses, one got extremely close to the object, fainted, and then the craft suddenly shot off, leaving a circular imprint on the grass.


Within the hour, a military team arrived and cleared the area.


Andrew Greenwood, a science teacher present during the sighting, backed the students’ accounts. Days later, he was visited at home by a man in a Royal Australian Air Force uniform and another in civilian clothes. Greenwood claimed they spoke to him in a threatening manner, warning him not to talk, citing national security and even threatening his career. Afterward, Greenwood became noticeably more reserved about the incident.


To this day, the Australian government has neither confirmed nor denied the event, leaving the Westall UFO case one of the most enduring and mysterious sightings in the nation’s history.

Uinta Basin, Utah, USA


For two years, the Sherman family lived their dream on a beautiful cattle ranch in Utah’s Uinta Basin—until it became a nightmare. At first, everything seemed normal: healthy cattle, a peaceful life. But soon, they were plunged into a series of terrifying, unexplainable events. Cattle began turning up mutilated, organs missing with no blood at the scene, no signs of struggle, and wounds made with laser-like precision—suggesting something far beyond natural predators.


As time passed, the phenomena escalated. Terry Sherman claimed to witness a fiery orange portal open in the sky above the ranch. From it emerged a silent, dark triangular object that hovered, then shot off like a streak of light as the portal vanished. Other sightings included glowing orbs, flying saucers, and even poltergeist-like activity.


Shaken and desperate, the Shermans eventually sold the ranch to Robert Bigelow, who commissioned investigations through his organization, NIDS (National Institute for Discovery Science). Later, the Pentagon’s AAWSAP (Advanced Aerospace Weapon Systems Applications Program) also investigated. While no definitive evidence of non-human intelligence was found, multiple credible witnesses—including scientists and government officials—reported unexplained phenomena. The mystery of what happened at the ranch remains unsolved to this day.

Undisclosed Location off The Southern Coast of California, USA


While conducting a training exercise off the coast of Southern California, the USS Nimitz and the USS Princeton encountered one of the most credible UAP incidents in U.S. military history. The Princeton was testing its then-new SPY-1 radar system when it began picking up strange anomalies—objects descending from 80,000 feet to 20,000 feet, hovering for hours, then shooting back up at impossible speeds. After troubleshooting the system, the radar returns became even clearer.


About a week later, Top Gun graduate Commander David Fravor and wingman Alex Dietrich were redirected mid-exercise to investigate one of the signatures. Flying F/A-18s, they reached the coordinates but initially saw nothing—until they spotted a disturbance on the ocean’s surface, a patch of white water about the size of a Boeing 737. Above it hovered a smooth, white, tic-tac-shaped object, moving erratically “like a ping pong ball in a cup,” according to Fravor.


As Fravor descended to 3,000 feet, the object suddenly mirrored his movements, then shot off at an extraordinary speed, vanishing from sight. All four aviators saw it. In 2023, Fravor testified under oath before Congress, stating the technology displayed was far beyond anything known to humanity—and that the military has no way to defend against it.

Above Lake Superior, USA/Canada Border


Most people exploring the UFO phenomenon have heard of alien abductions—but entire planes vanishing? That’s rarer. In November 1953, radar operators at the Ground Control Intercept Station in Sault Ste. Marie detected an unidentified craft flying at 500 mph through restricted U.S. airspace over Lake Superior. 1st Lt. Felix Moncla Jr. and 2nd Lt. Robert L. Wilson, stationed at Kinross AFB, were scrambled in an F-89C Scorpion to investigate.


Due to stormy weather, Wilson struggled to lock radar onto the erratic object. Guided by Calumet Air Force Station, Moncla descended to 7,000 feet. Soon, radar showed the two blips—Moncla’s jet and the UFO—merging. Seconds later, both vanished.


Despite an extensive, 29,000-square-mile search by U.S. and Canadian forces, no trace of the aircraft or object was ever found. Initially, the Air Force suggested a crash or mid-air explosion, later claiming the UFO was a Canadian C-47. The Royal Canadian Air Force denied having any aircraft in the area.


In his book The Flying Saucer Conspiracy, Major Donald Keyhoe proposed the object either collided with or "absorbed" the jet. Moncla’s gravestone reads: “Disappeared Nov. 23, 1953 intercepting a UFO over Canadian Border.” The mystery remains unsolved.

Pascagoula River, Mississippi, USA


On a crisp October night in 1973, Charles Hickson and Calvin Parker were preparing to leave their fishing spot on the Pascagoula River when they heard a sudden humming noise behind them. Turning around, they saw a blue light growing larger in the sky. Paralyzed and unable to move, they watched as an oval-shaped flying disc approached and hovered in front of them. Three 5-foot-tall beings with neckless, wrinkled skin, slit-like eyes, clawed hands, and strange protrusions for ears and noses floated out of the craft. The creatures levitated the men and guided them aboard.


Inside, Charles was held in place by two beings while a “Mechanical Eye” emerged from the wall and scanned his body. The creatures seemed robotic, going about their task with no interest in the men. Calvin remembered little about the event except for being punctured in the arm, which left a wound, but Charles experienced the entire examination they underwent.


The creatures returned the men to the riverbank, where they regained control of their bodies. Afterward, the men reported the encounter to the sheriff’s office. Sheriff Fred Diamond and Captain Glenn Ryder interviewed them separately to detect any inconsistencies in their stories. Despite their initial skepticism, the men’s accounts matched perfectly. However, to further test their credibility, the sheriff secretly left a recorder in the room where the two men were alone. When the tape was played back, it revealed the men’s raw fear and continued discussion of the traumatic event, showing that they truly believed what had happened. The mystery remains unsolved.

Huffman, Texas, USA


In December 1980, Betty Cash, Vickie Landrum, and her grandson, Colby, were driving on a Texas road when they noticed a bright light above the treetops. As the light approached, they saw a diamond-shaped craft, about the size of a water tower, hovering just above the treeline. Flames intermittently erupted from the base, radiating intense heat. Betty, driven by curiosity, stepped outside to observe, but the heat became unbearable, forcing her back to the car, which had become so hot she needed to use the sleeve of her leather jacket to open the door.


The craft rose slowly into the sky, and a rhythmic thumping noise grew louder, like an approaching tornado. The witnesses then saw 23 twin-rotor Chinook helicopters closing in on the craft. As the helicopters surrounded it, the heat dissipated, and Betty was finally able to start the car. The witnesses watched the craft disappear toward the moon, followed by the helicopters.


Later, all three began to feel ill, with flu-like symptoms and severe skin redness. Betty’s condition worsened, including swollen eyes and hair loss, resembling radiation exposure. Doctors confirmed this diagnosis. The witnesses linked their injuries to the military, having seen U.S. Air Force markings on the helicopters pursuing the strange craft. They sought accountability, but the military denied involvement, and the case was left unresolved. This encounter stands out as a potential government operation, with no mention of aliens.

New Hampshire, USA

On the night of September 19, 1961, Betty and Barney Hill were driving home to Portsmouth, New Hampshire, after a vacation in Canada when they noticed a bright light moving erratically across the night sky. Curious, they kept watching as it grew closer. Through binoculars, Betty saw a cigar-shaped craft with glowing lights. When the UFO descended rapidly, Barney pulled over to get a better look.


He claimed to see a disc-shaped object hovering in the air, with windows—and movement inside. Figures appeared to be watching him. Overcome with fear, Barney ran back to the car, shouting that “they’re going to capture us!” As they drove off, the couple reported hearing beeping and buzzing sounds that vibrated the entire car. Then, everything went blank.


When they regained awareness, they were 35 miles farther south, with no memory of the last two hours. Betty reported the encounter to a nearby Air Force base. Soon after, she began having vivid dreams of being taken aboard a craft by small, grey beings with large, wraparound eyes. Barney eventually began having nightmares too.


Distressed, they sought help from psychiatrist Dr. Benjamin Simon, who used hypnosis to recover their repressed memories. Separately, they described similar events: their car stalling, being paralyzed, and approached by 4-foot-tall beings. Barney said their eyes “spoke” to him telepathically, calming his fear. Betty recalled the beings telling her they meant no harm.


Both described being taken aboard the craft and subjected to invasive physical and reproductive exams. Afterward, they were returned to their car, waking up with the ship gone.


The Hills' story became the first widely publicized alien abduction case—and remains one of the most influential in UFO lore to this day.

Apache-Sitgreaves National Forest, Arizona, USA

On a clear November evening in Arizona’s Apache-Sitgreaves National Forest, Mike Rogers and his logging crew were finishing up for the day. Around 6 p.m., while driving home along Turkey Springs Road, Travis Walton, sitting shotgun, noticed a hazy golden light through the trees. Assuming it was campers or hunters, the crew continued until reaching a clearing—where the true source was revealed: a glowing, metallic disc-shaped craft hovering above the treetops, pulsing with golden light.


Travis jumped out of the truck and ran toward it, expecting it to flee. Instead, it emitted a deep hum that intensified, vibrating through the air and his body. As the others shouted for him to return, the disc suddenly discharged a bluish-green beam, striking Travis and flinging him violently to the ground. Believing he was dead, the crew panicked and fled, only to return minutes later—Travis and the craft were gone.


Walton awoke aboard the ship in pain and surrounded by short, pale beings with large, almond-shaped eyes. Panicked, he knocked one over and escaped the exam table, stumbling into a control room. There he encountered a taller, human-like figure in a clear helmet, who silently guided him to another room where similar beings sedated him with a gas mask.


Five days later, Walton reappeared at a gas station 30 miles from the abduction site—disoriented, dehydrated, and 10 pounds lighter, with a needle mark on his body. During his disappearance, locals suspected his co-workers of foul play, believing the alien story was a cover for murder. Each crewmember was questioned and given a polygraph—five passed, and one test was inconclusive, not failed.


Travis’s sudden return cleared their names. His case became one of the most famous abduction stories ever, inspiring the film Fire in the Sky. Alien abduction is terrifying—but so is being wrongly accused of murder with no proof to clear your name.

Varginha, Brazil

Anyone familiar with UFO lore has likely heard of the “Roswell Crash”—but Brazil has its own version: the Varginha Incident. A swirl of unconfirmed but widely shared claims paints a picture of a crashed UFO, an alien on the loose, and military involvement in a small Brazilian city.


On a January morning in 1996, Eurico Rodrigues de Freitas and his wife Oralina Augusta were outside doing farm work when they saw a strange, submarine-shaped craft silently floating over a cow pasture just outside Varginha. The object appeared damaged and losing altitude as it drifted toward the city, disappearing over the horizon. They kept quiet about it—until a much more dramatic encounter occurred hours later.


Around 3 p.m., three young women—Liliane and Valquiria Silva, and their friend Katia Andrade Xavier—were walking home when they spotted a crouching creature. It stood 4 to 5 feet tall, with oily brown skin, a large head bearing three horn-like protrusions, and glowing red eyes. The stench of sulfur filled the air. One of the girls screamed, startling the creature, which turned and locked eyes with them.


According to filmmaker James Fox’s documentary Moment of Contact, Liliane and Valquiria fled, but Katia froze, claiming to feel the creature’s fear as it seemingly begged her for help—telepathically. This emotional exchange became the film’s titular “moment of contact.”


When the sisters returned with their mother, the being was gone—but a footprint and the lingering sulfuric odor remained. Word of the encounter quickly spread. That evening, locals reported seeing military and police vehicles, along with fire trucks, surrounding a vacant lot—rumored to be where the alien had been captured. Some claimed it was taken to a local hospital under military guard, though no official records support this.


Rumors grew: that the creature was transferred to a military base, and that a man who allegedly transported it died from a bacterial infection contracted during contact. The Brazilian military later dismissed the entire event, stating the creature was a confused man with a mental disability, and the military activity was part of a scheduled drill.


A misidentification? A coincidence? Or did something truly unearthly happen in Varginha that day? The mystery remains one of the most intriguing in UFO history.

Malmstrom AFB, Montana, USA

Since the end of World War II, fears of nuclear war have loomed large—especially during the Cold War, when thousands of warheads stood ready for launch. While many of those weapons have since been dismantled, over 12,000 still exist today. The terrifying reality? It often takes just a few individuals to authorize a launch that could end life as we know it.


But what if that control wasn't entirely in human hands?


On March 16th, 1967, at Montana’s Malmstrom Air Force Base, former U.S. Air Force missile launch officer Robert Salas experienced something that still haunts him. Stationed 20 meters underground at the Oscar Flight Missile Silos, Salas received a routine call from a guard topside reporting strange lights in the sky. Thinking it was a prank or local aircraft, Salas brushed it off—until ten minutes later, when the guard called again, this time terrified and shouting.


According to Salas, the guard described a glowing, reddish-orange disc hovering silently just outside the front gate, pulsating eerily. Moments later, alarms blared inside the launch facility. Salas and his partner raced to the missile control board, only to watch in shock as one by one, all ten of their Minuteman nuclear missiles went offline—completely disabled, with no clear cause.


They were unable to launch or defend, even if ordered to. The Air Force later blamed the shutdowns on technical glitches and officially denied any connection to unidentified flying objects. But Salas and others involved have maintained their story ever since.


Whether it was extraterrestrial or not, the thought that an unknown force—intentional or accidental—can interfere with a nation’s nuclear arsenal is chilling. If something can shut them off… what’s stopping it from turning them on?
