UFO sightings in Portugal have fascinated both the public and investigators for decades, frequently appearing in UFO/UAP news. From high-altitude military encounters to bizarre biological anomalies, Portugal’s skies have hosted a series of mysterious events. In 1957, the Ota Air Base Encounter involved four Portuguese Air Force pilots witnessing an unidentified craft in controlled airspace. Just two years later, the Évora UFO Incident introduced a strange biological twist—an unknown organism linked to an aerial anomaly.
Beyond isolated sightings, Portugal has also recorded dramatic mid-flight interactions. The 1982 Military Pursuit saw a UFO maneuvering aggressively around a fighter jet, triggering an official investigation. Years later, in 1997, a glowing red object over Madeira left multiple witnesses baffled as it pulsed and vanished at high speed. Some of Portugal’s most alarming cases even involved military alerts—such as the 2004 Lisbon Radar Anomaly, where F-16s were placed on standby after an unidentified object was tracked on defense systems.
Not all sightings have involved military intervention, yet some still defy conventional explanations. The 2017 Algarve UFO Formation remains one of Portugal’s most visually striking cases, with 200 pulsating lights moving in perfect synchronization. These encounters, spanning decades, reinforce Portugal’s reputation as a country rich in unexplained aerial phenomena. Whether atmospheric, experimental, or extraterrestrial, UFO sightings in Portugal continue to fuel speculation, investigations, and the ever-growing search for answers in the skies.
Mysterious 1957 Military Encounter: UFO Sightings in Portugal’s Ota Air Base
On September 4, 1957, a significant event in UFO sightings in Portugal occurred involving four Portuguese Air Force pilots. Led by Captain José Lemos Ferreira, the squadron embarked on a routine nocturnal training mission from Ota Air Base. The other pilots were Sergeants Alberto Gomes Covas, Salvador Alberto Oliveira, and Manuel Neves Marcelino. Their flight path included the Spanish city of Granada, followed by the Portuguese cities of Portalegre and Coruche.
At approximately 22:30, near Portalegre, Captain Ferreira observed a luminous object above the horizon. Initially resembling a bright star, it exhibited dynamic color changes—transitioning from green to blue, with hints of yellow and red. The object expanded to five or six times its original size before contracting to an almost invisible point. This pulsating behavior persisted for several minutes, capturing the attention of all four pilots.
As the pilots continued their mission, the object descended toward the horizon on their left. Shortly thereafter, they observed a small yellow circle emerging from the main craft, followed by three additional circles. The primary object appeared approximately 15 times larger than these smaller ones, suggesting a mothership accompanied by subordinate crafts. Near Coruche, the main object executed a sudden descent, then ascended rapidly, seemingly attempting to intersect the pilots’ flight path. The smaller objects vanished during this maneuver.
Upon returning to Ota Air Base after a forty-minute flight, the pilots reported their encounter. Captain Ferreira dismissed conventional explanations such as Venus, weather balloons, or aircraft, emphasizing the extraordinary nature of the sighting. This incident remains one of Portugal’s most compelling UFO encounters, notable for its detailed witness accounts and the credibility of the military personnel involved.
The 1959 Évora UFO and the Unidentified Organism: A Unique Case in UFO Sightings in Portugal
​On November 2, 1959, a unique event occurred in Évora, Portugal. Multiple witnesses, including Joaquim Guedes do Amaral, saw an unusual aerial object. Around midday, a round, light-blue object appeared, fluctuating in size and moving erratically. A second, larger object followed, undulating like a jellyfish. Both ascended and vanished.
Shortly after, strange white filaments fell across the city. This substance, often called “angel hair,” covered trees, streets, and buildings. The phenomenon lasted for hours. Similar filaments were seen at Sintra air base earlier that day. A respected pilot, Conceição e Silva, reported the event.
Professor Amaral collected samples for analysis. Under a microscope, he found a small, tentacled organism. It measured about four millimeters and had a central body with ten appendages. A gelatinous, slightly yellowish layer surrounded it. The tentacles resisted pressure up to 350 grams. Over time, the organism changed color from yellow to brown.
Despite thorough research, scientists could not classify it. Some compared it to marine life, but no exact match was found. The samples were sent to the University of Lisbon. However, in 1978, a fire destroyed them along with related research.
This incident remains a mystery in UFO sightings in Portugal. The presence of a possible unknown organism sets it apart. It challenges conventional UFO reports, adding an unusual biological dimension.
1982 Military Pursuit: UFO Sightings in Portugal’s Airspace Shock Air Force Pilots
​On November 2, 1982, Portuguese Air Force pilot Lieutenant Júlio Miguel Guerra experienced a notable UFO encounter in Portuguese airspace. While piloting a DHC-1 Chipmunk trainer aircraft near Torres Vedras, Guerra observed a metallic-looking object maneuvering around his plane for approximately 15 minutes.
Guerra described the object as round, composed of two hemispheres resembling tight-fitting skullcaps. The lower section appeared reddish-brown with a central dark spot, while the central band featured a grid-like pattern, possibly illuminated. The object’s movements were unconventional, performing rapid vertical ascents and elliptical orbits around Guerra’s aircraft.
During the encounter, Guerra contacted air traffic control, prompting fellow Air Force officers, Carlos GarcĂŞs and AntĂłnio Gomes, to approach the location. Both pilots corroborated Guerra’s observations, witnessing the object’s maneuvers between their aircraft. They estimated the object’s size to be between 2.5 and 3 meters.
Following the incident, all three pilots submitted detailed reports to the Air Force. The Portuguese Air Force Chief of Staff at the time, General JosĂ© Lemos Ferreira, authorized a comprehensive investigation. The analysis concluded that the object exhibited speeds exceeding 300 mph during vertical maneuvers and approximately 1,550 mph while circling Guerra’s aircraft. ​
This encounter stands as a significant event in UFO sightings in Portugal, particularly due to the credibility of the witnesses and the thorough military investigation it prompted. The detailed descriptions and corroborative testimonies from multiple pilots underscore the incident’s importance in the study of unexplained aerial phenomena.
1997 Madeira UFO Encounter: A New Year’s Eve Mystery
​On December 31, 1997, in Funchal, Madeira, a series of UFO sightings captivated both locals and visitors. As New Year’s Eve celebrations unfolded, a reporter and her husband observed a stationary red light in the sky above Funchal. The light suddenly executed a tight circular maneuver, returned to its original position, and then accelerated vertically at high speed. This unexpected movement left the witnesses in awe. ​
Among the observers was a British couple who managed to videotape the hovering UFO, providing visual evidence of the event. Their footage added credibility to the numerous accounts from that evening. The incident drew attention from various media outlets and was later documented in compilations of global UFO sightings.
This sighting stands out in the history of UFO sightings in Portugal due to the convergence of multiple credible witnesses and the existence of video evidence. The detailed descriptions of the object’s behavior—a stationary light performing rapid maneuvers—challenge conventional explanations such as aircraft or atmospheric phenomena. Additionally, the presence of journalists among the witnesses ensured that the event received prompt and accurate media coverage, further solidifying its place in UFO lore.​
While no official explanation was provided, the Funchal sighting remains a topic of interest among UFO researchers and enthusiasts. The combination of eyewitness testimony and visual documentation contributes to its enduring intrigue. This incident exemplifies the broader phenomenon of unexplained aerial sightings that continue to puzzle observers worldwide.
2004 Air Force Radar Anomaly: High Alert Over UFO in Portugal’s Skies
​In June 2004, an unusual aerial phenomenon occurred over Portugal, prompting a significant response from both civilian and military authorities. Witnesses described observing an intense white light accompanied by a trail of smoke traversing the night sky. This phenomenon was detected by Portuguese Air Force defense radar, leading to a heightened state of alert with F-16 fighter jets placed on standby.
Air traffic controllers from Beja and Montijo, as well as firefighters at Lisbon Airport, confirmed that the object was not an aircraft. Paulo Lagarto of the Management Company of Portuguese Air Space reported that at 11:44 PM, the control tower in Porto detected an ascending object. This sighting had been reported 25 minutes earlier in Montijo and Beja as an unidentified object.
Fernando Monteiro, a leading investigator from the Department of Geology at Lisbon’s University of Sciences, dismissed the possibility of a meteor, stating that such an event would have been faster and noisier. Similarly, astronomer José Matos suggested that the intense light could have been the reflection of the Iridium satellite, known for its reflective antennas that catch sunlight.
This incident stands out in the history of UFO sightings in Portugal due to the coordinated response it elicited from various authorities and the subsequent media coverage. The event remains a topic of interest among UFO researchers and enthusiasts, reflecting the enduring intrigue surrounding unexplained aerial phenomena.
2017 Algarve UFO Formation: A Stunning Display in UFO Sightings in Portugal
On June 17, 2017, in Loulé, Algarve, Gary Purdon and his family witnessed an extraordinary aerial phenomenon. Around midnight, they observed a formation of approximately 50 pulsing lights at the front, followed by about 150 more, all moving in perfect formation. These lights pulsed rhythmically, akin to a dimmer switch being gently turned on and off. Despite their efforts, the family was unable to capture the spectacle using a £200 camera and a Samsung S7 Edge smartphone, highlighting the visual intensity and elusiveness of the event.
The lights traversed the sky from one horizon to the other, maintaining their formation without deviation. Witnesses described the pulsing as a slow, breathing-like effect, distinct from typical flashing or twinkling. The inability to photograph the phenomenon added to its mystique.
This sighting is part of a series of similar reports in Portugal during that period. Other witnesses from Lisbon to the Algarve recounted observing clusters of twinkling lights moving cohesively across the night sky. Explanations such as fireflies, seagulls, aircraft, or LED lanterns were proposed but failed to convince those who experienced the events.
The Loulé incident stands out in the history of UFO sightings in Portugal due to the number of lights observed and their precise formation. The consistent descriptions from multiple witnesses across different locations lend credibility to the accounts. Despite the lack of photographic evidence, the detailed testimonies contribute significantly to the ongoing discourse on unexplained aerial phenomena in the region.
In summary, the June 17, 2017, sighting in LoulĂ© remains a compelling case within Portugal’s UFO history. The combination of the number of lights, their synchronized movement, and the inability to capture them on camera continues to intrigue both witnesses and researchers alike.
