World UFO Day 2025: 10 Most Mysterious UFO Sightings That Still Leave Us Wondering
Share this article:
Every year on July 2, enthusiasts across the globe mark World UFO Day, a time to reflect on some of the most mysterious encounters humanity has ever recorded. From glowing discs in the sky to aircraft-defying physics, UFO sightings have puzzled witnesses and investigators alike. While some dismiss them as secret military experiments or weather phenomena, others believe they could be evidence of visitors from beyond Earth. Here’s a look at 10 of the most famous and mind-boggling UFO sightings and landings ever documented.
1. The Roswell Crash – USA, 1947
The legend began in Roswell, New Mexico, when a mysterious object crashed on a ranch. Initially dubbed a “flying disc” by the military, the narrative was swiftly changed to a weather balloon—fueling decades of suspicion that the truth was being hidden. Roswell remains UFO ground zero.
2. Capitol Encounters – Washington D.C., 1952
Bright lights zoomed over the White House and Capitol, detected on radar and confirmed by pilots. Jet fighters scrambled, but the objects vanished at impossible speeds. The U.S. Air Force never gave a satisfying explanation, keeping the mystery alive.
3. Britain’s Roswell – Rendlesham Forest, 1980
In Suffolk, U.K., U.S. Air Force personnel witnessed strange lights and encountered a metallic triangular craft. Odd symbols, elevated radiation levels, and multiple eyewitness accounts turned this into one of the U.K.'s most credible UFO reports.
4. Hudson Valley Sightings – USA, 1980s
From 1982 to 1986, thousands in New York’s Hudson Valley reported giant, silent, V-shaped crafts with bright lights. Seen by families, police, and pilots alike, these slow-hovering objects stirred debate: alien technology or black-budget military aircraft?
5. Belgium's Triangles – 1989–1990
A massive wave of sightings shook Belgium, with over 13,000 reports of low-flying, triangular UFOs. The Belgian Air Force sent fighter jets to investigate. Though radar picked them up, no aircraft could catch them. The government even acknowledged the events.
6. Mystery at Sea – Shag Harbour, Canada, 1967
Witnesses saw a glowing object crash into the sea near Nova Scotia. A full-scale search found no wreckage, but officials logged it as a genuine "UFO crash." Some believe something otherworldly now rests beneath the waves.
7. Classroom Close Encounter – Westall, Australia, 1966
Over 200 students and staff at a Melbourne school spotted a saucer-shaped craft land nearby. It hovered briefly, then vanished. While no official statement was released, reports of government pressure to stay silent only deepened the mystery.
8. Lights Over Phoenix – USA, 1997
A formation of massive, silent lights in a V-shape cruised over Arizona in one of the most widely witnessed UFO events. While the military claimed they were flares, thousands remain unconvinced, citing the sheer scale and silence of the spectacle.
9. Tehran Incident – Iran, 1976
Iranian fighter jets tried to intercept a radiant UFO over Tehran. Their equipment failed mid-flight but recovered when they retreated. The object displayed erratic, impossible movements and was later noted in U.S. intelligence documents.
10. Airport Anomaly – Chicago O’Hare, 2006
Airport staff and pilots saw a metallic saucer hovering over a terminal before it shot vertically through the clouds. Despite credible witnesses, the FAA chalked it up to “weather phenomena.” Many still believe it was something more.
Whether you’re a believer or a sceptic, these incidents continue to fuel our fascination with the unknown. On World UFO Day 2025 , take a moment to look up—you never know what might be watching from above.
