25 Unanswered Strangest Disappearances in History

Posted by , Updated on March 22, 2024

The mystery and intrigue that shroud a person’s disappearance often leaves us pondering on what really transpired. A certain small fraction that goes missing might have intentionally chosen that route for personal reasons, possibly to begin anew in an unknown place. Another slightly larger group might have been killed or have suffered fatal accidents in extremely bizarre circumstances that didn’t get reported due to the lack of witnesses. There still remains a significant quota that simply disappears with no rational explanation so far discovered for this phenomenon. You can delve into these puzzles for yourself by exploring these 25 most perplexing disappearances throughout history that still remain unsolved.

One of the biggest mysteries in history is the disappearance of the Ninth Legion, lost in the fogs of Britain during a military campaign.

What is known as the “Valentich disappearance” is a strange occurrence in the annals of UFOlogy that took place in 1978. The curious case of Frederick Valentich has been called Australia’s most famous aviation mystery and that’s not because he disappeared up in the skies, but because his final radio transmissions reported a UFO sighting. Ever since, a subculture of Australians, notably including Valentich’s father, believe he was abducted by aliens and may still be alive somewhere.
