The mysterious case of the Somerton Man, whose body was found on Somerton Beach in Adelaide, Australia in December 1948, remains unsolved to this day. The body was discovered dressed in a suit with polished shoes, but no identification was found. Despite an exhaustive search, no one was able to identify the man, and authorities even put a photo of the body in newspapers to no avail.

The cause of death was initially thought to be heart failure or poisoning, but no trace of poison was found during the autopsy. Fingerprints taken by authorities were also unidentifiable. Four months after the body was discovered, detectives found a hidden pocket sewn on the inside of the man's trousers containing a rolled-up piece of paper from a rare book called the Rubáiyát. The piece of paper had the words “Tamám Shud” on it, which means “it has ended.”

Despite months of searching for the exact book, authorities decided to bury the Somerton Man without identification. However, they took a cast of the bust and embalmed him to preserve him.

Eight months later, a man walked into the police station claiming he found a copy of the Rubáiyát in the back of his car parked near Somerton Beach. The book contained a torn part of the final page that matched the piece of paper found in the Somerton Man's trousers. Inside the book were a phone number and a strange code.

The phone number led authorities to a nearby woman named Jessica Thompson, who was evasive during her interview and claimed to faint when she saw the bust of the Somerton Man. She denied knowing the man but said she had sold the book to a man named Alfred Boxall. However, Boxall was still alive and had the copy of the Rubáiyát that Jessica had sold him. The code found in the book remains unsolved to this day.

The identity of the Somerton Man remains a mystery.

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.
