Photographs recently discovered in a family photo album from the 9/11 attacks have shone a whole new light on the devastation caused on that fateful day.

Here's the full story...

Now, September 11th, 2001, was the day that changed the world forever.

Nineteen militants associated with the Islamic extremist group, al Qaeda, hijacked 4 airplanes around the country and carried out suicide attacks against targets in the United States.

And was driven into the north tower of the World Trade Center at approximately 8.45 am.

Residents initially believed it to be an explosion in the tower...

The airplane was driven into the tower at such a staggering speed that many passersby and even people in the building believed it to be an explosion from the inside.

The impact left a gaping, burning hole in the eightieth floor of the skyscraper - instantly killing the hundreds of people on board the aircraft and on several floors of the building.

But the devastation didn't end there.

Eighteen minutes after the first impact, a second Boeing 767 - United Airlines Flight 175 - appeared out of the sky at a worryingly low altitude and was driven straight into the next-door south tower, crashing into the sixtieth floor.

The collision caused another huge explosion, which told the world that this wasn't an accident...

Debris was showered across central New York, causing locals to panic and take shelter in nearby and much lower buildings. But, devastatingly, hundreds of people were still trapped in both towers with no way of getting down past the burning holes in the center of the skyscrapers. This led to many perishing from the fires and people were even seen jumping and falling to their deaths from the towers to escape the unbearable smoke and heat.

American Airlines Flight 77 was also hijacked and began circling over downtown Washington D.C before crashing into the west side of the Pentagon military headquarters at 9.45 am. Collectively, sixty-four people were killed on board the aircraft and a further 125 military personnel and civilians who were in or around the Pentagon.

By 10.30 am, both the north and south tower of the World Trade Center collapsed into a massive cloud of toxic dust and smoke.

The steel structure of the skyscrapers, which had been built to withstand winds in excess of 200 miles per hour, simply could not withstand the tremendous heat of the burning jet fuel any longer than it already had.

Only 6 people in the towers survived at the time of the collapse.

There were many fortunate enough to be on the lower floors of the towers when both crashes occurred meaning they were evacuated safely.

However, many people were still trapped in the buildings or were making their way down the fire escapes when they began to collapse.

This wasn't the end of the tragedies...

As the towers were collapsing and causing complete chaos to New York City, a fourth airplane - United Flight 93 - was hijacked after leaving Newark Liberty International Airport in New York. However, the crew and passengers on board were made aware of the 3 other attacks and fought back against the 4 hijackers.

According to Business Insider, one of the passengers, Thomas Burnett, Jr., told his wife over the phone:

"I know we're all going to die. There are 3 of us who are going to do something about it. I love you, honey."

The passengers and crew of Flight 93 showed unimaginable courage and bravery...

There was an immense struggle in the cockpit, which caused the airplane to flip and plummet to the ground at 500 miles per hour.

The wreckage and debris of the airplane were found in a rural field near Shanksville in western Pennsylvania at 10.10 am. All forty-four people on board were killed instantly.

The then-President, George W. Bush, delivered a televised address from the Oval Office at 9 pm that night, where he stated:

"Terrorist attacks can shake the foundations of our biggest buildings, but they cannot touch the foundation of America. These acts shatter steel, but they cannot dent the steel of American resolve."

President Bush promised justice for the victims of 9/11...

"The search is underway for those who were behind these evil acts. I have directed the full resources of our intelligence and law enforcement communities to find those responsible and to bring them to justice..." he went on to say in his speech that evening.

Well, 2 decades have now passed since the attacks took place, and the country is still grappling with feelings of anger and loss.

As of September 2018, more than 2,000 of the courageous men and women who assisted at the scene have since passed away as a result of 9/11 related illnesses.

It's a date that the country may never fully move on from...

And every year, new reminders of the attacks are discovered.

And the most recent discovery was made in none other than an old family photo album.

A Connecticut teenager stumbled across some remarkable photos from the scene of the attacks while flipping through an old Valentine's Day-themed album that once belonged to his great-aunt, Maryann Puglisi-Muñoz.

Nineteen-year-old Liam Enea told Newsweek that he was even able to locate the building from which his great-aunt snapped the photos.

"Through the photos, I determined that she lived in an apartment at 310 Greenwich Street in New York City, whose terrace faced south toward the World Trade Center," he said.

He also explained that her photos had been snapped on a disposable camera.

"On that day and in the aftermath, she took the photographs on a type of disposable camera. I determined that she lived there by looking at an aerial photograph of the buildings and locating the nearest residential high-rise north of the towers."

Liam decided to share his discovery on TikTok...
