What are your favorite strange mysteries in the world? Could it be the assassination of JFK? Or The Bermuda Triangle? 

Here are my Top 3 greatest mysteries in the world. 

No. 3: Jack the Ripper.

Jack the Ripper, who is also known as “The Whitechapel Murder” or “Leather Apron,” was known as possibly one of the most unidentified serial killers recorded in history. 

He was an English serial killer, who, from August-November 1888, murdered at least five women who were prostitutes. 

He wasn’t caught due to three main reasons — the poor environment and policing at Whitechapel, no technology for police to use to catch Jack, and the police department’s inexperience.

The case remains open. 

No. 2: Kenneth Arnold’s UFO sighting.

On June 24, 1947 aviator Kenneth Arnold, while flying from Chehalis, Washington, to Yakima, Washington, reported that he saw a shiny unidentified flying object flying past Mount Rainier. 

Suddenly, it was a bright light, just like a flash.

At first Arnold thought it was another plane that was flying just 15 miles past him, but what caught his attention was that plane wasn’t flashing at him. 

Arnold also stated that the objects looked to be flying in a single horizontal plane, and it had the tail of a chinese kite.

The unidentified flying object was occasionally flipping around and darting side to side, and at that moment he realized that the objects were not flying objects. Still, he figured military aircraft were being tested.

The case remains a mystery. 

No. 1: Spring-Heeled Jack

Spring-Heeled Jack, who was part of English Folklore in Victorian England, was considered a bogeyman who could breathe fire and jump unnaturally high. Was he a demon or simply an extraordinarily agile human?

Residents of London began to report sightings and bizarre attacks of Spring-Heeled Jack around mid 1837, describing him as a “ghost, imp, or devil” in the shape of a large white bull.

Jack would ring a doorbell and if a woman answered, he ripped her clothes with his claws, according to multiple police reports.

Many other citizens reported seeing Spring-Heeled Jack ambushing other people who were walking late at night.

And throughout the rest of the year more and more similar reports continued to trickle into Victorian England. Some thought it might be a group of men dressing up as the monster to scare people. 

This remains a mystery.
