Marco Aurelio Simon: The Vanishing Scout
On June 8, 1985, Marco Aurelio Simon, a 15-year-old scout, embarked on a camping trip to the Pico dos Marins mountains in Brazil. Accompanied by his scout leader and fellow scouts, Marco was excited for the adventure ahead. However, this trip would soon turn into one of Brazil’s most perplexing mysteries.
The group arrived at the mountain range and set up camp on the property of a local guide, Alfonso Xavier. Strange occurrences began almost immediately, with the group’s belongings mysteriously rummaged through and eerie feelings of being watched reported by some members. These unsettling events seemed to foreshadow the tragedy that would unfold the next day.
The Disappearance
During their hike up the mountain, one of the scouts, Osvaldo, injured his knee, forcing the group to turn back. Marco volunteered to return to camp ahead of the group to seek help for Osvaldo. Despite initial objections, the scout leader, Juan, allowed Marco to go alone, instructing him to mark stones along his path with the number “240” to ensure the group could trace his route.
Marco set off, marking three stones before vanishing without a trace. When the group returned to camp hours later, they found Marco’s backpack outside his tent, but Marco himself was nowhere to be found.
The Search Efforts
Over the next 28 days, one of the largest search operations in Brazilian history was conducted. Military personnel, police, rescue specialists, and even helicopters scoured the area, but no evidence of Marco was ever found. The case grew even stranger when the search party reported hearing frantic whistling and seeing flashes of blue light in the forest during the second night of their search.
Theories and Unanswered Questions
Marco’s disappearance remains unsolved, with theories ranging from foul play to supernatural involvement. Why did Marco stop marking stones after the third one? If he returned to camp, why didn’t he seek help as planned? And what were the mysterious blue lights seen during the search? These questions continue to baffle investigators and fuel speculation.

The Kinross Incident: A Jet Vanishes

On November 23, 1953, First Lieutenant Felix Eugene Moncla and Second Lieutenant Robert L. Wilson were dispatched from Kinross Air Force Base in Michigan to intercept an unidentified radar blip over Lake Superior. Flying an F-89C Scorpion fighter jet, the duo pursued the object, which appeared to jam their onboard radar system.
As ground control monitored the radar, they witnessed Moncla’s jet approach the unidentified object until the two blips merged into one. Moments later, both the jet and the object disappeared from radar entirely.
The Bizarre Radio Transmission
Despite losing contact with Moncla and Wilson, a strange radio transmission was received over half an hour later. Moncla’s voice was heard saying, “I think we better…” followed by indistinct words before the transmission went silent. This raised more questions than answers, as it suggested the jet had not crashed immediately after disappearing from radar.
The Search and Contradictions
A massive search operation covering over 10,000 square miles yielded no trace of the jet, its pilots, or any debris. The official U.S. Air Force report claimed the radar blip was a Canadian aircraft that had veered off course, but Canadian officials denied having any planes in the area. This contradiction, along with the lack of physical evidence, led many to speculate that Moncla and Wilson encountered a UFO.

Owen Parfitt: The Man Who Vanished Without Moving
In 1768, Owen Parfitt, a paralyzed man living in Shepton Mallet, England, was placed on his sister’s porch to enjoy the summer sun. Hours later, when his sister returned to bring him inside, Owen was gone. His blanket and coat were left behind, but Owen had vanished without a trace.
The Impossible Disappearance
Owen’s disappearance is particularly baffling because he was paralyzed and unable to move on his own. Farmhands working nearby reported seeing nothing unusual, despite being within earshot and clear view of Owen. The cottage was located near the town center, surrounded by other homes, making it nearly impossible for Owen to vanish unnoticed.

Theories and Speculation
Some theorize that Owen may have staged his own disappearance as a final prank, while others suspect foul play. However, neither theory explains how he could have vanished from such a busy area without anyone noticing. The supernatural explanation remains popular, as the circumstances of Owen’s disappearance defy logic.
