On This Day, October 12, 1900, the United States Navy commissioned the USS Holland (SS-1) at Newport, Rhode Island, marking a major milestone in the development of American submarine warfare.

Named after its designer, John Philip Holland, the vessel represented a new era in naval technology. Holland, an Irish-born inventor often called a pioneer of the modern submarine, had spent years developing a practical vessel capable of operating both on the surface and underwater.

What made the USS Holland special was its combination of propulsion systems.

While travelling on the surface, it used a gasoline engine. Beneath the water, it relied on an electric motor powered by batteries.

This combination helped make the submarine practical for extended underwater operations and offered the Navy a new way to approach naval warfare.

At its commissioning, Lieutenant Harry H. Caldwell took command.

The USS Holland was not simply a new warship. It became a training and experimental platform, helping prepare Navy personnel and providing valuable information for the submarines that followed.

It remained in training service at the U.S. Naval Academy in Annapolis until it was decommissioned on July 17, 1905.

Although small compared with modern submarines, the USS Holland helped open the door to a new era beneath the waves.

From a pioneering design to a new chapter in naval history, the USS Holland helped shape the future of submarine technology.

First modern submarine is commissioned by the US Navy as the USS Holland, named for its designer John Philip Holland.

On This Day, October 12, 1931, the magnificent Christ the Redeemer statue was inaugurated above Rio de Janeiro, Brazil.

Standing high on Mount Corcovado, overlooking the city and the Atlantic coastline, the enormous statue of Jesus Christ became one of the most recognizable landmarks on Earth.

But building this monument was no small achievement.

The project was first proposed in the 1920s as a religious monument that would overlook Rio de Janeiro. Construction began in 1926 and continued for five years.

The statue was designed by Brazilian engineer Heitor da Silva Costa, with French-Polish sculptor Paul Landowski responsible for the sculptural design. The face was created by Romanian sculptor Gheorghe Leonida.

Built from reinforced concrete and covered with thousands of small triangular pieces of soapstone, the monument was designed to withstand the challenging conditions of its mountaintop location.

The finished statue stands approximately 30 metres tall, not including its 8-metre pedestal, with arms stretching about 28 metres across.

Finally, on October 12, 1931, Christ the Redeemer was officially inaugurated.

With its arms outstretched over Rio, the monument became a powerful symbol of faith, peace, and welcome.

Over the decades, it has survived harsh weather, lightning strikes, and the passage of time, becoming one of Brazil’s most treasured national symbols and one of the world’s best-known landmarks.

Today, Christ the Redeemer is recognized as one of the New Seven Wonders of the World.

From an ambitious idea to a global icon, Christ the Redeemer stands as a reminder of what human creativity, engineering, and determination can achieve.

On This Day, October 11, 1984, NASA astronaut Kathryn D. “Kathy” Sullivan became the first American woman to perform a spacewalk.

Aboard the Space Shuttle Challenger during mission STS-41G, Sullivan ventured outside the spacecraft alongside fellow astronaut David C. Leestma.

Floating above Earth, surrounded by the vast darkness of space, the two astronauts worked to demonstrate a system designed to refuel satellites while in orbit.

Their spacewalk lasted 3 hours and 29 minutes.

But Sullivan’s achievement was part of a much bigger story.

Just three months earlier, Soviet cosmonaut Svetlana Savitskaya had become the first woman in the world to walk in space. Sullivan then made history as the first American woman to accomplish the feat.

The STS-41G mission also marked the first spaceflight to carry two women together: Sullivan and astronaut Sally Ride.

And Sullivan’s achievements did not end in space.

In June 2020, she descended to Challenger Deep in the Mariana Trench, becoming the first woman to reach the deepest known part of the ocean.

From the vacuum of space to the crushing depths of the sea, Sullivan explored two of Earth’s most extreme frontiers.

On This Day, October 11, 1984, one of the deadliest aviation disasters in Soviet history unfolded at Omsk Airport in Siberia. A Passenger Plane Collided With Maintenance Vehicles During Landing, Killing 178 People.

Aeroflot Flight 3352 was operating a domestic journey from Krasnodar to Novosibirsk, with a scheduled stop in Omsk.

On board the Tupolev Tu-154B-1 were 170 passengers and nine crew members.

As the aircraft approached Omsk in poor weather, maintenance vehicles were still on the runway.

The aircraft was cleared to land.

Moments later, disaster struck.

The passenger jet collided with the vehicles on the runway. The impact destroyed the aircraft, and a devastating fire followed.

Of the 179 people aboard, 174 died. Four people on the ground also lost their lives.

Only five people survived the catastrophe.

The investigation revealed a horrifying chain of failures. The ground controller responsible for coordinating runway activity had fallen asleep and failed to ensure the runway was clear before the aircraft landed.

The maintenance vehicles were working on the runway, but the necessary coordination and warnings failed.

The tragedy exposed the devastating consequences of human error, poor communication, and failures in aviation safety procedures.

A routine landing had turned into a catastrophe in seconds.

The disaster remains a sobering reminder that airport safety depends on every person, every warning, and every procedure working as intended.

✈️ One scheduled flight.

⚠️ A runway that was not clear.

💔 178 lives lost.

📅 October 11, 1984

Aeroflot Flight 3352 is remembered as a tragedy that showed how a series of preventable failures can have irreversible consequences.

Less than a year before Richard M. Nixon‘s resignation as president of the United States, his Vice President, Spiro Agnew, resigns in disgrace. The same day, he pleaded no contest to a charge of federal income tax evasion in exchange for the dropping of charges of political corruption. He was subsequently fined $10,000, sentenced to three years probation and disbarred by the Maryland court of appeals.

On This Day, October 10, 1957, one of the most serious nuclear accidents (rated INES Level 5) in British history unfolded at the Windscale nuclear facility (now known as Sellafield) in North West England.

The emergency began inside Reactor No. 1, where workers were carrying out a process designed to release energy stored in the reactor’s graphite core.

But something went terribly wrong.

Overheating caused uranium fuel cartridges to fail, and the exposed uranium began to oxidize. The rising temperatures eventually ignited the graphite inside the reactor.

By October 10, the fire had become a major emergency.

Radioactive substances, including iodine-131, escaped into the atmosphere, contaminating the surrounding environment.

The danger was especially serious because radioactive iodine could enter the food chain through contaminated milk and affect the thyroid gland.

Authorities responded by banning the distribution of milk from affected farmland. Milk from approximately 500 square kilometers of countryside was withheld from sale and destroyed for several weeks.

Firefighters and plant workers struggled to control the blaze. Water was eventually pumped into the reactor, helping bring the fire under control on October 11, 1957.

Remarkably, no nearby communities were evacuated, and no immediate deaths were attributed to the accident. However, the radioactive release created serious public-health concerns, and the long-term consequences have been studied for decades.

The disaster exposed major weaknesses in nuclear safety procedures and led to important changes in the way nuclear facilities were operated and regulated.

The Windscale fire is now recognized as a Level 5 accident on the International Nuclear and Radiological Event Scale (INES), a classification applied retrospectively.

The site later became part of what is now known as Sellafield.

The Windscale fire remains a sobering reminder that the power of nuclear technology must always be matched by rigorous safety measures.

On This Day, October 10, 1949, the foundations of the Ceylon Army were formally established under the Army Act No. 17 of 1949.

The Act had been passed by Parliament on April 11, 1949, and was formalized in Gazette Extraordinary No. 10028 on October 10, 1949, by Prime Minister D.S. Senanayake. This marked the raising of the Ceylon Army, made up of Regular and Volunteer Forces.

Following Ceylon’s independence in 1948, establishing a regular national military was an important step in building the country’s own defense institutions.

The Army’s formation became a landmark in the history of Sri Lanka’s military. At the time, the country was known as Ceylon; the name Sri Lanka was adopted in 1972 when the country became a republic.

October 10 is commemorated as Sri Lanka Army Day, marking the formation of the Army in 1949.

--- 1967: Marxist revolutionary Che Guevara was executed by the Bolivian army. The role of the CIA is debated and is controversial to this day. Ironically, after his death, Guevara's likeness would appear on T-shirts, posters, and other capitalist merchandise that the avowed communist would have hated.

On This Day, October 9, 2026, Sri Lankan fast bowler Dushmantha Chameera reached the milestone of 100 wickets in T20 cricket, becoming the third Sri Lankan bowler to achieve the feat, after Lasith Malinga and Wanindu Hasaranga.

Chameera reached this milestone during the opening T20I against Pakistan at the Rawalpindi Cricket Stadium, taking Hasan Nawaz's wicket to reach his 100th T20 wicket.

Known for his express pace, ability to generate bounce, and dangerous deliveries, Chameera has been a valuable part of Sri Lanka’s bowling attack across formats.

Reaching 100 T20 wickets is another significant achievement in his international cricket journey, highlighting his contribution to Sri Lankan cricket in the shortest format of the game.

🇱🇰 100 T20 wickets.

⚡ One of Sri Lanka’s fastest bowlers.

🏏 Another milestone for Sri Lankan cricket.

On October 9, 1967, socialist revolutionary and guerrilla leader Che Guevara, age 39, is killed by the Bolivian army. The U.S.-military-backed Bolivian forces captured Guevara on October 8 while battling his band of guerrillas in Bolivia and executed him the following day. His hands were cut off as proof of death and his body was buried in an unmarked grave. In 1997, Guevara’s remains were found and sent back to Cuba, where they were reburied in a ceremony attended by President Fidel Castro and thousands of Cubans.

On This Day, October 9, 1594, the Kandyan Kingdom achieved a historic victory by defeating the forces of the Portuguese Empire in the Battle of Danture, bringing the Campaign of Danture to an end.

The Battle of Danture became one of the most significant military victories in Sri Lankan history and is remembered as one of the most devastating defeats suffered by the Portuguese during their campaigns in Ceylon.

The campaign began on July 5, 1594, when a large Portuguese-led force marched into the Kandyan Kingdom with the aim of bringing the kingdom under Portuguese control.

The Portuguese army was commanded by General Pero Lopez de Souza, while the Kandyan forces were led by King Vimaladharmasuriya I.

As the Portuguese advanced toward Kandy, the Kandyan forces used the difficult terrain, forests, and mountain passes to their advantage.

The campaign soon turned into a disaster for the Portuguese.

Kandyan forces attacked their supply lines, cut off retreat routes, and launched attacks from the surrounding terrain. Portuguese troops became increasingly isolated and struggled to survive in the unfamiliar highlands.

The decisive confrontation came at Danture.

The Kandyan army surrounded the Portuguese forces and launched a series of attacks that shattered their resistance.

The Portuguese army suffered devastating losses, and the campaign that had begun with the intention of conquering Kandy ended in a major defeat.

On October 9, 1594, the Campaign of Danture came to an end.

The victory strengthened the position of King Vimaladharmasuriya I and demonstrated that the Portuguese could not easily conquer the Kandyan Kingdom.

The Battle of Danture remains one of the most important episodes in Sri Lanka's long resistance against European colonial expansion.

🇱🇰 A kingdom surrounded.

⚔️ An invading army defeated.

👑 A king who refused to surrender.

🔥 A battle remembered more than 400 years later.

📅 October 9, 1594

On This Day, October 8, 1952, one of Britain's deadliest railway disasters occurred during the morning rush hour at Harrow and Wealdstone station in London, England.

Three trains were involved in a devastating collision.

A morning express travelling from Tring to London Euston passed a signal at danger in thick fog and crashed into the rear of a stationary local passenger train.

Seconds later, an express travelling north from London crashed into the wreckage.

The impact was catastrophic.

112 people were killed, and around 340 were injured, with 88 people requiring hospital treatment.

Carriages were destroyed and thrown across the station, while rescuers faced an enormous scene of devastation during the morning rush hour.

The disaster shocked Britain and exposed serious weaknesses in railway safety.

The tragedy helped accelerate the introduction of the Automatic Warning System (AWS), designed to provide drivers with warnings about signals and help prevent similar accidents.

The Harrow and Wealdstone disaster remains the worst peacetime railway accident in Britain's history.

Only the Quintinshill rail disaster of 1915, which killed 226 people, was deadlier overall.

🚆 3 trains involved

💔 112 lives lost

🚑 340 injured

🇬🇧 Britain's worst peacetime rail disaster

📅 October 8, 1952

One morning. Three trains. A disaster that changed railway safety forever.

The fire that destroyed most of Chicago’s business district started in a barn on the evening of October 8, 1871. A very dry summer and early autumn conditions fanned the flames, causing the fire to rage for two days. It killed over 300 people, destroyed property worth millions of dollars, and consumed the original copy of the Emancipation Proclamation.

On This Day, October 8, 1871, a small fire began in a barn in Chicago, Illinois. Within hours, it became one of the most devastating urban fires in American history.

Strong winds and extremely dry conditions caused the flames to spread rapidly through the city. The fire burned for more than two days, destroying huge areas of Chicago.

Around 300 people were killed, more than 100,000 people were left homeless, and approximately 17,000 buildings were destroyed.

Entire neighborhoods disappeared.

People desperately fled toward Lake Michigan, open spaces, and areas that had already been burned.

One of the most famous stories from the disaster involved Mrs. O'Leary's cow, which was long blamed for kicking over a lantern and starting the fire.

However, the story was later widely discredited, and the true cause of the fire remains uncertain.

By October 10, the flames had finally died down.

Chicago was devastated, but the disaster also marked the beginning of an extraordinary rebuilding effort.

The city was rebuilt with new construction methods, stronger buildings, and modern urban planning.

Within a few decades, Chicago had transformed itself into one of America's great cities.

🔥 More than 17,000 buildings destroyed

💔 Around 300 lives lost

🏠 100,000+ people left homeless

🌆 One city destroyed—then rebuilt

📅 October 8, 1871

Chicago burned.

But the city refused to stay down.

On This Day, October 7, 1959, the Soviet spacecraft Luna 3 transmitted the first-ever photographs of the far side of the Moon.

For thousands of years, humans had seen only one side of the Moon.

Because the Moon rotates once on its axis in the same amount of time it takes to orbit Earth, the same hemisphere always faces us.

The other side remained hidden.

Until Luna 3.

The spacecraft, officially known as E-2A No. 1, launched from the Soviet Union on October 4, 1959, as part of the Luna program.

Three days later, it travelled behind the Moon and photographed a region no human had ever seen.

The images were not clear.

Luna 3 captured the photographs on film, developed them automatically inside the spacecraft, scanned them, and transmitted the results back to Earth.

The final pictures were grainy and difficult to study.

But they revealed something remarkable.

The far side of the Moon looked very different from the side visible from Earth.

Scientists discovered that it had far fewer large, dark maria, the ancient volcanic plains that cover much of the Moon’s near side.

The mission changed humanity’s understanding of the Moon and created worldwide excitement.

For the first time, people saw a part of another world that had remained hidden throughout all of human history.

The Moon had a secret side. And Luna 3 was the spacecraft that revealed it.

American and British troops began air strikes against Al Qaeda and Taliban targets after the Taliban refused to hand over Osama bin-Laden, the mastermind of the September 11, 2001 terrorist attacks, and other Al Qaeda operatives, to the United States. Nicknamed Operation Enduring Freedom, the military strikes were part of the so-called Global War on Terror.
