For decades, the Loch Ness Monster, or “Nessie,” has been a subject of fascination and speculation for people all over the world. The creature is said to inhabit the depths of Loch Ness, a large freshwater lake in Scotland. Sightings of Nessie date back to the sixth century, but it wasn't until 1933 that the first modern sighting made headlines, when a local couple claimed to have seen a “strange creature” in the lake.

Since then, there have been countless other reports of sightings, photographs, and even videos purporting to show Nessie. Some claim the creature is a plesiosaur, an extinct marine reptile, while others believe it could be a large eel or a type of unknown aquatic creature. Despite numerous expeditions and investigations, however, no conclusive evidence of Nessie’s existence has ever been found, leaving the mystery of the Loch Ness Monster unsolved.

The Strange Disappearance of D.B. Cooper

On Wednesday, Nov. 24, 1971, a mysteriously normal man named Daniel Cooper bought a one-way ticket on Northwest Airlines from Portland, Oregon to Seattle, Washington. He was in his mid-40s, wore a suit, an overcoat, brown shoes, a white shirt, and a black tie. He carried a briefcase and a brown paper bag. Before takeoff, he ordered a drink and gave a note to a flight attendant saying he had a bomb.

The note demanded $200,000 in cash, four parachutes, and a fuel truck to refuel the plane. After the demands were met, Cooper let some passengers and crew off the plane but kept some on board. During the flight, he put on sunglasses and then jumped out of the plane with two parachutes and the money. He was never found.

Despite years of searching, authorities have not been able to identify Cooper or find out what happened to him. The case is still considered one of the greatest mysteries in the history of the FBI and the United States.
