UFO sightings occur frequently around the world, but only a few involve direct military confrontations or police pursuits. Here are some of the most thrilling reported clashes between human forces and extraterrestrial visitors.
10. Tehran UFO Incident

On September 19, 1976, Iranian air force commanders in Tehran began receiving calls from civilians reporting strange lights in the sky over the city. No Iranian aircraft were airborne at that time. Initially, the commanding general assumed it was a star, but after stepping outside to view the lights, he quickly ordered fighter jets to be launched for interception.
Two F-4 Phantom jets were scrambled. The second jet, piloted by Lieutenant Parviz Jafari, got close enough to visually identify the object, which appeared as a ball of flashing light. As Jafari approached, another object detached from the first. Believing he was under attack, Jafari attempted to fire a Sidewinder missile. However, as soon as he activated the missile, the plane's electrical systems failed, causing a complete power loss. He dove away, regaining power only after distancing himself from the object. Jafari continued to monitor the object from a safe distance, noticing a second object detach and dive toward the ground, eventually resting on the desert surface.
The following day, the Iranian air force arrived at the location where the object was reported to have landed, but they found no trace of it. They did, however, detect a beeping transmission, traced it to a nearby home, and discovered a small beeper transponder. Critics of the account suggest that the light could have been the planet Jupiter, which appears incredibly bright in the night sky. Additionally, the F-4 aircraft flown by Jafari was notorious for mechanical and electrical malfunctions, and one investigator speculated that the beeper could have come from a United States C-141 that may have been dislodged by turbulence when flying over the nearby mountains.
9. Fukuoka Incident

1948 was a significant year for military UFO encounters. At that time, aerial radar was just beginning to be installed on combat aircraft, meaning not every U.S. Air Force fighter was equipped with it. This makes the Fukuoka incident particularly intriguing, as it involved an F-61 Black Widow night fighter, which did have radar. The aircraft was on a night patrol over Japan when the radar operator detected an unidentified object nearby. The F-61 pilot decided to pursue the mysterious object.
As the crew closed in on the object, it suddenly accelerated from 320 km/h (200 mph) to 1,900 km/h (1,200 mph). After slowing down, the object allowed the F-61 to catch up once again, only for it to make a sharp turn and dive below the plane. The F-61 pilot attempted to follow, but was swiftly outmaneuvered. The crew came close to intercepting the object four more times, but it managed to evade them each time just before they reached gun range. On the final attempt, the crew managed to clearly observe the target, describing it as a stubby craft, 6 to 9 meters (20-30 ft) in length, with no visible design features other than a bullet-shaped fuselage.
This may have been the first instance where pilots utilized airborne radar to track a UFO. Interestingly, the nearby ground radars failed to detect the object during the 10-minute dogfight. While the unusual characteristics of the object have been cited as evidence by UFO enthusiasts, it's noteworthy that one crew member pointed out that the object resembled the German Me-163 rocket fighter, which the US Air Force had captured at the time.
8. Gorman Dogfight

In 1948, another US Air Force pilot engaged in a battle with a UFO over Fargo, North Dakota. On October 1, experienced pilot George Gorman took off to intercept an unusual radar contact. Flying his P-51, Gorman quickly closed the distance to the target. Once in visual range, he observed that it was a ball of light that flashed intermittently. Gorman prepared his guns and began to chase the object.
The flashing light outpaced Gorman, but since it was also making turns, Gorman realized he could attempt a turning fight, using the maneuverability of his P-51 to try and cut it off. Suddenly, the object executed a sharp turn and headed directly toward Gorman, passing just a few hundred feet above him. Startled by the near miss, Gorman quickly attempted to regain sight of the object, but it had ascended too high for the P-51 to pursue. Men in the Fargo control tower were observing the scene through binoculars, and a nearby Piper Cub pilot also witnessed the aerial confrontation.
At the time, the Gorman Dogfight was regarded as one of the most prominent UFO sightings, and it continues to be a legendary case frequently cited by UFO researchers. However, the Air Force quickly dampened the enthusiasm surrounding the event. They claimed that minutes before Gorman's takeoff, they had launched a weather balloon but failed to inform the Fargo controllers. Even UFO researchers are divided on the issue, with some believing the Air Force's explanation to be plausible. However, the fact that at least three different eyewitnesses supported the account leads others to feel that the dogfight still remains open to further interpretation.
7. Mantell Incident

While George Gorman managed to survive his alleged UFO encounter, P-51 pilot Thomas Mantell was not as fortunate that same year. At Fort Knox, military air controllers received reports of a bright, white- and red-colored object hovering motionless in the sky. Four P-51s were quickly launched to pursue the object, though one turned back before they could locate it. The remaining pilots saw the object but could not identify it clearly. Mantell then climbed steeply, while the other pilots disengaged. The last thing they saw was Mantell's aircraft spiraling to the ground before crashing.
The US Air Force quickly launched an investigation into the incident. While UFO enthusiasts quickly suggested that a UFO was responsible for Mantell's death, the Air Force offered several explanations for the crash. One key factor was that Mantell did not have an oxygen mask, which could have caused him to lose consciousness at an altitude of about 8,000 meters (25,000 feet). The plane spiraled out of control and disintegrated in the sky. Transcripts of the pilots' communications revealed that the other two pilots were unable to see the object Mantell pursued, with one asking, 'What the hell are we looking for?' The object was later identified as Venus. According to the Air Force, the case was closed — Mantell had chased Venus, and due to his inexperience with the P-51, he lost consciousness and crashed.
UFO enthusiasts remained adamant, with witnesses on the ground coming forward to say they saw a UFO, not just the light of Venus. Astronomers investigating the case stated that Venus was only 33 degrees above the horizon at the time, far from the location where Mantell was flying. In response, the Air Force revised its explanation, suggesting the object was a weather balloon. However, no weather balloons were recorded as being launched during that time. As a result, UFO believers continue to argue that an extraterrestrial presence was responsible for the tragic fate of the young pilot.
6. Torres UFO Encounter

Milton Torres's 1957 UFO encounter is remarkable because it involved air controllers directly ordering pilots to shoot down an unidentified flying object. Torres was stationed in England, piloting the F-86D, a radar-equipped variant of the famous F-86 Sabre fighter. This version of the F-86 used a salvo of rockets as its primary weapon and was among the first jet interceptors to incorporate radar technology.
On May 20, 1957, air controllers detected a UFO on radar and immediately scrambled Torres to intercept. They instructed him to engage full afterburner as he pursued the target. After reaching altitude, Torres inquired if he could turn off the afterburner, but controllers insisted he maintain maximum afterburner as he closed in on the object. This request seemed odd, as the F-86D was already operating at its top speed. As Torres approached, he managed to pick up the target on his radar.
Without warning, ground control instructed Torres to launch rockets at the target when it was within sight. This unexpected order left Torres startled, but he knew it was genuine. As he neared the object, it appeared as a vague, indistinct circle. Just 10 seconds from intercept, the UFO suddenly accelerated and vanished from his radar scope. Ground control lost its lock on the object and immediately told Torres to secure his rockets and return to base.
The close encounter and the possibility of launching his rockets left Torres rattled. The following day, after returning from a patrol, a man in a blue trench coat approached him and took him to a nearby office for questioning. After the interrogation, Torres's squadron commander instructed him never to speak of the incident, as it was considered an 'important matter of national security.' In 1988, Torres finally decided to share his story, though he was uncertain why it was now deemed acceptable to discuss the event, given that he had been explicitly told not to.
5. Portage County UFO Chase

In 1966, police officers in Portage County, Ohio, witnessed a UFO descending from the sky and hovering over their area. The disc-shaped object was intensely bright and was first spotted by two officers, Deputy Sheriff Dale Spaur and Mounted Deputy Wilbur 'Barney' Neff, who had just left their patrol car to investigate an abandoned vehicle. As they were examining the vehicle, they saw the object approaching from the treetops, heading directly toward them. Stunned, the two officers watched as the UFO passed overhead and hovered a few hundred meters away.
The officers quickly contacted the dispatcher. By this point, the UFO began moving once again. The dispatcher gave the officers permission to pursue the strange object. As the officers chased the UFO, it stayed just out of their reach. Eventually, the chase crossed into Pennsylvania, where local officers joined in. After 30 minutes of pursuit, the officers looked up to see fighter jets flying toward the object. When the jets closed in, the UFO abruptly stopped and shot upwards at an incredible speed, disappearing from sight.
Air Force officials later dismissed the event as a coincidence of two astronomical occurrences. They claimed that Spaur and Neff had seen an exceptionally bright satellite and then followed Venus all the way to Pennsylvania. Furthermore, they denied scrambling any jets to intercept the UFO. While the case faded into obscurity, one peculiar detail that UFO researchers focus on is that Neff seemed to develop symptoms of PTSD following the incident, which seems unusual for someone who was allegedly just chasing Venus.
4. The Disappearance Of Felix Moncla And Robert Wilson

On November 23, 1953, Lieutenants Felix Moncla and Robert Wilson were dispatched from Kinross Air Force Base to intercept a mysterious radar contact near the Wisconsin-Canada border. The two men were flying an F-89 Scorpion, a jet designed for interception missions and equipped with airborne radar. As they got closer to the target, Wilson, the radar operator, had difficulty tracking the object, so ground control took over the guidance of the interception.
As Moncla neared the target, the radar operators saw the F-89 and the object merge into a single contact on the radar screen. Almost immediately, the object continued moving in the same direction, but Moncla and Wilson were no longer on the radar. Search and rescue teams were sent to locate the missing pilots, but poor weather conditions hampered their efforts. After a few days, Moncla and Wilson were officially declared dead. Air Force investigators quickly issued a report stating that the mysterious object was a Canadian airliner that had gone off course. However, all Canadian airlines denied having any aircraft in the area during the time of the incident.
The official explanation was that Moncla had mistakenly pursued a Canadian airliner, experienced vertigo in the night conditions, and crashed his fighter into a nearby lake. With the case making local headlines, UFO enthusiasts speculated that Moncla had either collided with a UFO or been abducted. The fact that no wreckage of the F-89 was ever found fueled further conspiracy theories.
In 2006, the story took an unusual turn when a diving company, the Great Lakes Diving Company, claimed to have discovered the wreckage of the F-89 in a lake. They not only presented the fighter's wreckage but also released images showing an object on the lake bed, which they alleged to be the object Moncla had collided with. When experts later determined the images were fabricated, the Great Lakes Diving Company mysteriously vanished.
3. Battle Of Los Angeles

In the aftermath of the Pearl Harbor attack, Los Angeles was gripped by intense wartime anxiety. On February 23, 1942, a Japanese submarine surfaced off the California coast and launched a strike on local oil refineries. When the news of the attack reached the city, both the military and citizens feared a more significant assault was imminent. That night, military spotters observed strange blinking lights hovering over a defense plant. The anti-aircraft (AA) teams were put on high alert, but after a few hours, the lights vanished, and the crews were called off.
The next night, spotters once again reported something unusual in the sky above Los Angeles. This time, they described a large, glowing object. Unlike the previous night, where the situation resolved without incident, this time, every AA gun in the city opened fire into the sky. Ground observers continued to report strange lights as the barrage of gunfire continued, but despite the intense action, no conclusive evidence emerged that the AA fire had any impact. Eventually, the crews were told to stand down.
Almost immediately, conspiracy theories began circulating. The following day, Secretary of the Navy Frank Knox called the incident a false alarm, insisting that there were no planes in the sky. However, multiple eyewitnesses from the ground came forward, claiming to have seen something clearly. A photograph surfaced showing a bright disk illuminated by searchlights. Official reports, however, stated there was nothing in the sky and that the gunfire was aimed at the explosions of anti-aircraft shells in the air. After the war, Japan denied any air attacks on Los Angeles, and the incident seemed to be dismissed as a misunderstanding.
Nevertheless, several unusual aspects of the event have kept UFO researchers and conspiracy theorists intrigued. Eyewitnesses reported seeing lozenge-shaped objects in the sky, years before the UFO craze began in the United States. Additional reports released by the War Department after the war further muddied the waters, revealing that between one and five unidentified aircraft had been detected over Los Angeles that night—directly contradicting the Navy's official account. These discrepancies have led some UFO enthusiasts to believe that the Battle of Los Angeles was one of the largest confrontations between humans and extraterrestrials ever witnessed.
2. Dulce Wars

Dulce, New Mexico, is a quiet town that may not seem remarkable at first glance, but for conspiracy theorists, it's a place of intense interest, rivaling the fame of Area 51. To the casual observer, there's nothing particularly extraordinary about Dulce, but according to these theorists, it's home to a secret subterranean facility where humans and extraterrestrials collaborate to create hybrid technology. Yet, the relationship between the two species wasn't always as peaceful as it may sound.
A man named Philip Schneider came forward with claims that he was involved in the construction of this hidden base back in 1979. Schneider worked as an engineer on the project and was uneasy about the presence of special forces soldiers during the construction. The tension escalated when Schneider and his team encountered a group of 7-foot-tall aliens while digging. A firefight broke out between the humans and the aliens. Schneider was struck by an energy beam, which burned some of his fingers, but the battle continued, resulting in 60 human casualties before the aliens withdrew.
Believers in the Dulce Base theory often point out that there are multiple underground facilities throughout the United States involved in operations against hostile extraterrestrial forces. While this might sound highly improbable, political scientist Michael Barkun argues that there may be some elements of truth to these rumors. During the Cold War, the U.S. constructed a vast network of underground ICBM bases, which may have fueled the rumors of secretive underground research centers. Mixing Cold War-era ICBM bases with alien conspiracy theories has led to the creation of stories like the Dulce Wars.
1. Rajasthan UFO Downing

Not every encounter between UFOs and military jets took place in the past. On January 26, 2016, Indian Air Force radar operators detected a balloon-shaped object near the India-Pakistan border. In response, an IAF Su-30 fighter jet was dispatched to intercept the object, which was moving slowly along the border. Upon contact, the Su-30 pilot shot down the object, and its wreckage fell nearby. The Indian Air Force quickly began efforts to recover the debris.
The Indian Air Force has kept details about the incident under wraps, only disclosing that they have recovered five triangular metal fragments that are currently undergoing further analysis. The official stance is that the object in question was merely a weather balloon that originated from Pakistan.
However, local villagers have added more intrigue to the story. They claim that before and during the time the Su-30 fighter jet was intercepting the object, they heard a series of powerful explosions. A total of five explosions were reported, which could be heard from as far as 5 kilometers (3 miles) away. The shockwaves from the blasts were so strong that some buildings in the area sustained minor damage. Interestingly, this wasn't the first time villagers had heard such loud explosions.
The weather balloon explanation seems far-fetched, and alternative theories are emerging. Some speculate that the object was a secret Pakistani reconnaissance plane. Others continue to support the UFO theory, drawing parallels with the infamous 1947 Roswell incident in the United States. Regardless of the true nature of the event, ‘India’s Roswell’ is likely to keep UFO researchers occupied for years to come.
