Alcatraz was the most secure prison in the world.

Sharks. Freezing waters. Guards who swore no one could ever break out.

But on the night of June 11, 1962, three prisoners did the impossible.

Here’s the real story behind one of history’s greatest prison escapes: Image
Alcatraz Federal Penitentiary sat on a lonely island in San Francisco Bay.

It housed America’s most dangerous criminals—Al Capone, Machine Gun Kelly, and Robert Stroud.

With strong ocean currents, freezing waters, and no land in sight, Alcatraz was considered inescapable.
But they underestimated three men:

Frank Morris – A genius with an IQ of 133, known for escaping prisons.

John Anglin – A skilled swimmer.

Clarence Anglin – John's younger brother, equally good in the water.

They weren’t just prisoners. They were escape artists. Image
The plan wasn’t just a spur-of-the-moment idea.

Morris, the mastermind, spent over a year designing the escape.

With the help of Allen West (who ultimately got left behind), they devised a plan: Image
1. Dig their way out – Using stolen spoons, they chipped away at the vents in their cells for months.

2. Create decoys – They built fake heads from soap, cement dust, and real human hair (stolen from the barbershop). Image
3. Make a raft – They stitched together 50+ raincoats and sealed them with steam pipes to make a waterproof raft.

4. Find the perfect exit – They discovered a ventilation shaft that led to the roof. Image
At 9:30 PM every night, the men used “Happy Hour” (music hour) to hide the noise of their digging.

Over time, they cleared a hole big enough to crawl through, leading to an unguarded utility corridor.
June 11, 1962—9:30 PM:

Morris and the Anglin brothers crawled through their cell vents and climbed up pipes to the roof.

They used a wrench made from a bed frame clasp to unscrew the vent cover.
Then, they scaled down a 45-foot pipe, ran across the prison yard, climbed a 15-foot fence, and reached the shoreline.

By 11:00 PM, they inflated their raft and disappeared.

But Allen West's hole was too small. By the time he got out, the others were gone. Image
At 7:15 AM, the guards discovered the dummy heads in their beds.

Alcatraz was in chaos.

But the escapees were already gone.

Or were they?

The FBI, U.S. Marshals, and Coast Guard launched an all-out search. Image
What they found was chilling:

June 12 – A homemade paddle was found floating near Angel Island (the escapees’ likely destination).

June 14 – A waterproof bag containing family photos, phone numbers, and a letter to Clarence Anglin washed ashore. Image
June 22 – A life vest with bite marks on the inflation tube was found 100 yards off Alcatraz.

July 1962 – A Norwegian ship spotted a body in a prison uniform 20 miles off the Golden Gate Bridge. But it was never recovered.
The FBI officially closed the case in 1979, declaring the men “presumed drowned.”

For decades, rumors, clues, and theories suggested they survived.
Theory 1: They Died in the Water

The current was strong, and without proper navigation, they could have been swept out to sea.

But this theory has one major flaw:

Bodies that drown in San Francisco Bay usually surface within days.

No bodies were ever found.
Theory 2: They Survived & Escaped to South America

The Anglins were expert swimmers, used to icy waters.

Their mother received roses for years—sent with no name.

1973 – The Anglin brothers allegedly attended their mother’s funeral in disguise.
2015 – A photo surfaced showing two men in Brazil who strongly resembled the Anglin brothers.

2018 – The FBI received a letter allegedly written by John Anglin, claiming they survived but that Frank Morris had died in 2005.

The letter was tested for fingerprints—but the results were inconclusive.
In 2003, the TV show MythBusters attempted the escape:

- They built a raft using the same raincoat method.
- They paddled across the bay successfully.
- They made it to shore.

Their conclusion?

The escape was 100% possible. Image
The U.S. Marshals still list the escapees as wanted men.

If alive today, they’d be in their 90s.

The case remains open until they are proven dead or turn 99 years old.

Alcatraz closed in 1963, just a year after the escape.

To this day, no one knows for sure if they survived. Image
What do you think?

Did they make it? Or did they drown in the cold waters of the bay? Image

In 1910, America’s banking system was collapsing.

Six men with 1/4 of the world’s wealth boarded a train in secret to a private island.

There, they created the blueprint for the Federal Reserve.

Here's the untold story of the most powerful institution in U.S. history 🧵 Image
Image
In the early 1900s, U.S. banking was chaotic.

Banks were small, unregulated, and prone to collapse.

The Panic of 1907 triggered mass bank runs.

The U.S. economy nearly imploded, and Congress was desperate for a fix.
Senator Nelson Aldrich, head of the National Monetary Commission, quietly invited 5 of the nation’s top financiers:

1. Paul Warburg – Kuhn, Loeb & Co.

2. Frank Vanderlip – National City Bank of New York (Citibank)

3. Henry P. Davison – J.P. Morgan & Co. Image

In 1347, the Black Death killed 50 million people (50% of Europe) in just 5 years.

It wasn’t just a plague but a nightmare that rewrote history.

Here’s how the deadliest pandemic in history changed the world forever: Image
Image
The plague began far from Europe.

Historians believe it originated somewhere near the Gobi Desert or the Mongolian steppes.

Some pointed to Lake Issyk-Kul, where strange deaths had been reported as early as the 1330s.
In 1343, the Mongol leader Janibeg laid siege to the Genoese trading city of Caffa (Feodosia).

As his army camped outside the town, something strange happened: his soldiers began dying.

They developed swollen buboes, high fevers, and vomited blood before succumbing within days.

In 1944, a German U-boat vanished with 50 men on board.

For decades, no one knew what happened.

66 years later, a diver found it 400 feet below the Bay of Genoa.

The crew was still sealed inside.

This is the haunting story of U-455: a WWII mystery buried beneath the sea. Image
Image
During WWII, German U-boats were known as the "Grey Wolves."

They prowled the oceans, targeting Allied supply ships with ruthless precision.

These submarines were celebrated in Nazi propaganda as symbols of invincibility, and their crews were considered elite soldiers.
But the discovery of U-455 challenged the notion of U-boat dominance and raised questions about its tragic end.

The discovery of U-455 sparked an investigation led by divers, historians, and military experts.

Among them was Roberto Rinaldi, a former Cousteau crew diver.

In 1945, Hitler had a plan to bomb New York from space.

A spaceplane faster than the speed of sound, nuclear warheads, and flying saucers.

This wasn’t science fiction.

It was the Nazi's real plan for world domination.

Here’s the story of how it started and why it failed: Image
Image
By 1944, Nazi Germany was losing the war.

Allied forces were closing in on all fronts, and the once-feared German war machine was crumbling.

But Hitler and his top generals were obsessed with a final, decisive weapon:

A “Wunderwaffe” (Wonder Weapon) that could turn the tide.
Key scientists:

Wernher von Braun – The father of modern rocketry.

Eugen Sänger – Visionary behind a supersonic spaceplane.

Werner Heisenberg – Nobel Prize-winning physicist at the forefront of nuclear fission research. Image

In 331 BC, Alexander the Great founded a city for gods and geniuses.

At its heart stood a library with every book ever written.

Then, in a tragedy, it was reduced to ash.

This is the story of Alexandria: civilization’s greatest loss of knowledge 🧵 Image
Image
When Alexander the Great invaded Egypt in 332 BC, he saw an opportunity to create a city that would link his empire to the Mediterranean.

He sought a location that was both a military stronghold and a cultural hub. Image
A legend says that in a dream, Homer appeared to Alexander, reciting verses about an island off Egypt’s coast, Pharos.

Alexander chose this site to build Alexandria, naming it after himself.

To ensure the city’s grandeur, he enlisted the greatest minds of his time to design it.

In 1972, a French scientist locked himself 440 feet underground alone, in total darkness.

No clocks. No sunlight. No contact. For 180 days.

When he emerged, he believed it was day 151.

This is what happens when your brain loses all sense of time: Image

Michael Siffre wasn’t new to isolation experiments.

In 1962, he spent two months in a glacier cave to study how the human body perceives time in the absence of external cues.

But a decade later, he decided to push the boundaries even further.
The cave was located in Texas, deep underground.

It was completely sealed off from the outside world.

Siffre had: A sleeping bag.

A small supply of food and water. Image
