The Roswell Incident is one of the most talked-about UFO incidents worldwide. A mysterious object crashed on a ranch close to Roswell, New Mexico, in July 1947. The U.S. military initially described it as a "flying disc," but they subsequently changed their claim and referred to it as a weather balloon. Many people thought that the government was hiding an alien spacecraft because of this abrupt change. People still travel to Roswell in search of answers even after several decades have passed.

2. Washington, D.C. UFO Incident, USA (1952)

In July 1952, several unknown flying objects were spotted over the Capitol Building and the White House in Washington, D.C. Pilots confirmed seeing bright lights in the sky, while air traffic controllers saw odd blips on their radar. Several days passed during the sightings, and major newspapers even carried the stories. When the UFOs were intercepted by fighter jets from the U.S. Air Force, they swiftly disappeared. Even now, this incident cannot be explained.

3. The Rendlesham Forest Incident (1980), UK

Often referred to as "Britain's Roswell," this incident took place in Suffolk, England, in December 1980. Strange lights in the forest were reported by U.S. Air Force personnel stationed at RAF Woodbridge and RAF Bentwaters. Some even reported touching a metallic triangular object bearing odd symbols. According to reports, radiation was discovered at the landing site, and the lights came back on the following night. There has never been a satisfactory explanation.

Between 1982 and 1986, in the Hudson Valley of New York, thousands of people claimed to have seen big, silent, V-shaped lights in the sky. Families, police officers, and pilots frequently witnessed these UFOs hovering slowly over residences and highways. They were perceived as alien ships by some, and as secret military craft by others. One of the biggest mass UFO sightings in American history, the mystery is still unsolved.

5. Belgian UFO Wave (1989–1990), Belgium

Belgium experienced a wave of UFO sightings between 1989 and 1990, primarily of large, triangular craft with lights underneath. Even the Belgian Air Force used F-16 jets to pursue the UFOs after more than 13,000 people reported seeing them. Unknown flying objects were tracked by the radar, but pilots were unable to capture them. This was one of the most credible UFO sightings in Europe because the Belgian government took the sightings seriously.

6. The Shag Harbour Incident (1967), Canada

In October 1967, locals in Shag Harbour, Nova Scotia, saw a glowing object crash into the ocean. Authorities believed it was a plane crash and launched a search operation, but no wreckage was ever found. The Canadian government recorded the event as a “UFO crash in the ocean.” Many still believe that something not from this world sank beneath the waters of Shag Harbour.

7. The Westall UFO Incident (1966), Australia

In April 1966, more than 200 teachers and students at Melbourne's Westall High School claimed to have seen a flying saucer land in a nearby field. After remaining for a few minutes, the craft rose and quickly took off. Authorities allegedly told some students to keep quiet. The mystery surrounding this uncommon daytime sighting was increased by the fact that no formal report was ever made public.

8. The Phoenix Lights (1997), USA

One of the most observed and enigmatic UFO phenomena in history is the Phoenix Lights.

Witnesses insist what they saw was real and unexplained, while the FAA denied it was a UFO, claiming it was weather-related.
