A renovation project saved thousands of lives on 9/11

On September 11, 2001, American Airlines Flight 77 struck the Pentagon at 9:37 a.m., killing 189 people. Few people know this part: the death toll could have been much higher. But there was a renovation project underway at the time of the attacks.

The Pentagon’s five-sided structure is divided into five "wedges," and workers had been renovating them one at a time. Flight 77 struck the wedge that had just been completed. Of the 4,500 people who normally worked in that section, only about 800 had moved back in. Without the reinforced construction and the incomplete occupancy, experts believe the casualties would have been catastrophically higher.

The Cold War and the hot dog stand

In the middle of the Pentagon’s five-acre center courtyard once stood a modest hot dog stand. According to a Cold War legend (one still retold by official Pentagon tour guides on every public tour), between the 60s and the 80s, Soviet satellite images tracked large groups of high-ranking military officials converging on that small building at the same time every day.

Soviet intelligence reportedly concluded the structure must be the entrance to some underground bunker in America. In reality, all it did was sell lunch. In 2006, the original stand was torn down, and a sandwich shop was built in its place.

Its construction began on September 11th, exactly 60 years before the attack

Builders broke ground on the Pentagon on September 11, 1941. That was exactly 60 years to the day before the September 11, 2001, terrorist attacks that would strike the same building.

Construction had been ordered by Army Brigadier General Brehon Somervell, who wanted a permanent headquarters for the Defense Department to replace its then-17 scattered offices across Washington, D.C.

The project was extraordinarily ambitious: plans called for the world’s largest office building to be completed in just 16 months. In the end, the conception, design, and construction of the entire Pentagon building took a total of 15 months.

The same person oversaw its construction and the Manhattan Project

Colonel Leslie Groves of the Army Corps of Engineers took charge of Pentagon construction in August 1941. He worked six days a week and drove his team relentlessly, at one point employing more than 15,000 workers around the clock.

When the Pentagon was finished in January 1943, Groves was assigned to lead the Manhattan Project, America’s secret program to build the atomic bomb . His deputy, Captain Robert Furman, followed him into the Manhattan Project as chief of foreign intelligence. Together, the men who built the world’s largest office building went on to produce the weapon that ended World War II.

Why is it shaped like that?

The Pentagon’s iconic five-sided shape was the consequence of a geographic accident. The original site selected for the building, near Arlington Cemetery, **happened to be bordered on five sides by roads. **Architects designed the structure to fit those boundaries, producing a pentagonal floor plan. Then President Franklin D. Roosevelt intervened: worried the massive building would obstruct the view of Washington, D.C. from Arlington, he ordered the site moved to its current location along the Potomac River. But the five-sided design had already been drawn up, and nobody changed it.

It was the first desegregated building in Virginia

When the Pentagon was designed in 1941, segregation was the law in Virginia. Original plans called for doubled bathroom facilities: separate ones for Black and white employees, as required by Virginia statute. But President Roosevelt had signed Executive Order 8802 in June 1941, prohibiting racial discrimination in federal employment and government contracting.

As a federal building, the Pentagon was exempt from Virginia law. It became the only building in the state where segregation was not enforced. A fully desegregated federal workplace that opened in 1943. The doubled bathrooms were built anyway, as the plans were too far along to revise, but were never used as separately designated spaces.

7

Its construction was surprisingly frugal and incredibly fast

Ground broke on September 11, 1941, and construction finished on January 15, 1943, just 16 months later. More than 15,000 workers were on site around the clock. Wartime office shortages were so severe that employees moved into completed wings before the rest of the building was finished. Steel was too scarce to use extensively, so builders relied almost entirely on reinforced concrete. The 689,000 tons of sand and gravel required came directly from the nearby Potomac River, cutting transportation costs. The project was budgeted at $35 million, but the final bill was $63 million, which would translate to over $900 million in today’s dollars.

You can walk between its farthest points in only 7 minutes

The Pentagon is the world’s largest low-rise office building: 6.5 million square feet of space, which is three times the total floor area of the Empire State Building. Each of its five outer walls is 921 feet long. It has 7,754 windows and 17.5 miles of corridors. Approximately 26,000 military and civilian employees report for work there every day.

Despite that scale, the building’s concentric ring design is so efficient that it takes only about seven minutes to walk between its two farthest points.

9

The man who secretly lived inside its walls

During construction, Colonel Groves drove his deputy, Captain Robert Furman, so relentlessly that Furman rarely left the building. To cope, Furman had contractors build him a small, windowless apartment hidden inside the walls of the Army’s Ordnance Division. In this private room, he could sleep and shower without leaving the premises.

When construction ended and personnel dispersed, knowledge of the hidden room was never passed on to building management. Months later, when Furman returned to Washington on Manhattan Project intelligence business, he found the apartment undiscovered and exactly as he’d left it.

For over a year, he would slip back to the Pentagon, pop open a wall panel, spend the night, and emerge in the morning with his suitcase. He was finally caught in 1943 and forced to surrender the keys. It was never disclosed whether the secret apartment was maintained or eventually absorbed back into the official floor plans.

It houses over 30 restaurants, including everyone's favorite chains

The Pentagon feeds roughly 26,000 people a day, and its dining options read less like a military headquarters and more like a mall food court. The main Concourse Food Court, which opened in September 2009 and seats 875 people, is the largest of several dining areas.

Confirmed chains currently inside the building include McDonald’s, Five Guys, Subway, Popeyes, Starbucks (multiple locations), Dunkin’ (two locations), Panera Bread, Taco Bell, Panda Express, Baskin-Robbins, Potbelly, Jamba Juice, and Moe’s Southwest Grill, among others. The building also houses a CVS pharmacy, a florist, a jeweler, and a dry cleaner. In the summer of 2024, Potbelly became the first restaurant to open in the center courtyard. Yes, the very spot where the legendary Cold War hot dog stand once stood.

"Hound Dog" , Elvis Presley

Elvis made this song his signature, and it's hard to imagine it belonging to anyone else. But "Hound Dog" was written in 1952 by Jerry Leiber and Mike Stoller, and was first recorded by Big Mama Thornton, a blues singer from Alabama. Her version was a raw, powerful blues track, and it was a genuine hit.

Elvis recorded his version in 1956 and turned it into something faster, rockabilly, electrifying . For anyone who grew up in the '50s or '60s, it probably takes you right back to a specific moment: a sock hop, a drive-in, a transistor radio on a summer night. It carries a kind of pure rock-and-roll energy: rebellious, playful, unstoppable.

2

"Livin' on a Prayer" , Bon Jovi

Pumping fists, packed arenas, everyone screaming "Whooooa, we're halfway there!", it's the kind of energy that doesn't age. Jon Bon Jovi and Richie Sambora wrote it together in 1986, along with songwriter Desmond Child , pulling inspiration from the working-class New Jersey world around them.

The song hit number one in the U.S. and became an anthem for anyone who's ever had to scrape by and stay hopeful. It brings out something almost joyful in people: this defiant, communal "we're going to make it" spirit.

3

"I Will Always Love You" , Whitney Houston

Most people under 50 think this is a Whitney Houston song, but Dolly Parton wrote it back in 1973, sitting in Nashville. She was leaving her mentor and business partner, Porter Wagoner, to go solo, and the song was her way of saying goodbye: with love, but firmly.

Then Whitney came along in 1992 for The Bodyguard soundtrack and turned it into a stadium-sized emotional explosion. Where Dolly's version was warm and heartfelt, Whitney's was pure power. It connects to just about everyone, but especially to people who've ever had to let someone go. Which version do you like best?

4

"Respect" , Aretha Franklin

This is one of those cases where the cover so thoroughly eclipses the original that most people don't even know an original exists. Otis Redding wrote and recorded "Respect" in 1965, and it was a decent soul hit for him; a man asking his woman for a little respect when he comes home.

Then Aretha Franklin got hold of it in 1967, rewrote parts of it, added that now-iconic spelling-out of the word, and completely flipped the meaning . Suddenly, it was a woman demanding respect from men, from society, from everyone. It became an anthem of the civil rights movement, the women's movement, and basically every movement that involved people standing up and saying enough.

5

"Girls Just Want to Have Fun" , Cyndi Lauper

Cyndi Lauper made this song her own so completely that it's almost shocking to learn she didn't write it. Robert Hazard, a Philadelphia-based musician, wrote it around 1979 as a kind of tongue-in-cheek song from a man's point of view, about his own desire to just have fun without commitment.

When Cyndi recorded it in 1983, she completely reframed it: it became a declaration of independence for young women who just wanted to live their lives on their own terms . If you had a daughter, a niece, or any teenage girl in your life in the '80s, you heard this song approximately ten thousand times.

6

"Nothing Compares 2 U" , Sinead O'Connor

Few music videos have hit people as hard as Sinead O'Connor, alone on screen, tears streaming down her face, singing this song in 1990. It felt impossibly raw and personal. But the song was written by Prince back in 1984, and was first recorded by a side project of his called The Family.

Sinead stripped it down and made it devastating. It became one of the most emotionally powerful recordings of the decade . You probably heard it on adult contemporary radio, or remember exactly where you were the first time you really listened to it. It's a song about grief and absence and not being able to fill a void someone left behind.

7

"I Love Rock 'n' Roll", Joan Jett & the Blackhearts

Few songs scream pure, unapologetic rock and roll like this one. But Joan Jett didn't write it: a British glam rock band called The Arrows did, back in 1975, in London. Lead singer Alan Merrill said he wrote it as a direct response to the Rolling Stones' "It's Only Rock 'n Roll," which he felt was a little too apologetic about loving the music.

Joan Jett saw The Arrows perform it on British TV in 1976 while touring the UK with The Runaways, and the song stuck with her . She recorded it in 1981, and it rocketed to number one, sitting there for seven weeks. You've heard it blasting from jukeboxes, at sports events, in movie montages, at pretty much every party where someone wanted to get the energy up fast.

8

"I Don't Want to Miss a Thing" , Aerosmith

Tyler belting it out, that unmistakable raspy voice: it feels so Aerosmith. But the song was actually written by Diane Warren, one of the most prolific and successful songwriters in pop history , who penned it in 1998 specifically for the movie Armageddon. Warren has said she wrote it while watching her boyfriend sleep, thinking about not wanting to miss a single moment with someone you love.

Aerosmith recorded it, and it became their first number-one pop hit. It hits hard for anyone who's ever been deeply in love, or who's lost someone and wishes they'd paid more attention while they had the chance.

9

"Bette Davis Eyes", Kim Carnes

This was the biggest song in America in 1981, and it spent nine weeks straight at number one on the Billboard Hot 100 . Kim Carnes' raspy, smoky delivery made it feel completely hers. But the song was written in 1974 by Jackie DeShannon and Donna Weiss, both inspired by a classic old Hollywood film . DeShannon recorded her own version, but it barely registered.

Seven years later, Carnes took it into a Los Angeles studio, added a driving synth arrangement that was pure early MTV, and transformed it into the sound of an era. The real-life Bette Davis, then 73 years old, wrote personal letters to the songwriters and to Carnes to thank them for making her "a part of modern times." The song connected with anyone who'd ever been dazzled by someone they couldn't quite figure out, which is pretty much everyone.

10

"Blame It on the Rain" , Milli Vanilli

You probably remember the Milli Vanilli scandal: in 1990, it came out that Fab Morvan and Rob Pilatus, the two beautiful, dreadlocked faces of the duo, hadn't actually sung a single note on their records . The real vocals were by studio singers. Their Grammy was revoked. It was a whole thing.

But before all that exploded, "Blame It on the Rain" was a legit #1 pop hit in 1989. It was written by Diane Warren (yes, the same woman who wrote "I Don't Want to Miss a Thing"), and it's a smooth, sweet ballad about blaming the weather for a relationship going wrong. You probably heard it on pop radio, maybe slow-danced to it without knowing what you were slow-dancing to.

Skip Air Force One

Beyond the wishes of any president, flying on a commercial airline is completely forbidden under any circumstances. Due to security concerns, Air Force One is meant to be the only way a president can travel by air. But there is actually a historic exception in this matter. In 1973, during the oil crisis, Richard Nixon flew on a regular United Airlines flight to California . The trip was meant to show support for energy-saving efforts nationwide.

2

Break the two-term rule

Did you know that before Franklin D. Roosevelt, presidents were not limited to two terms? They mostly followed a tradition started by George Washington, the first US president in 1789, who decided to step down after his second term. It wasn’t until the 22nd Amendment in 1951 that two terms became the official legal limit to moderate the accumulation of power in one person.

Roosevelt, who was president from 1933 to 1945 , was the only president to break that tradition because of the country's exceptional situation: During the Great Depression and World War II, many Americans wanted solid leadership. He ended up winning four elections, but died of a stroke in 1945 during his fourth term.

3

Take diplomatic gifts home

Presidents have to buy their own gifts? Truth is, they can receive gifts from foreign leaders, but they cannot always keep them as personal presents. If a gift is expensive enough to go over the government’s "minimal value" limit, it is treated as a gift to the American people. From there, the White House Gift Unit helps decide what happens to it. In fact, the president or First Lady can still keep the gift, but only if they buy it at fair market value. This rule exists so that a diplomatic gift does not appear to be a personal favor.

4

Own their official speeches

A president can stand at a podium and deliver a speech heard around the world, but that does not mean he is the private author of those words. Under U.S. copyright law, official presidential speeches are usually considered part of the public record because they are part of the job. That means people can quote them, share them, and reuse them more freely than a normal copyrighted text. You could say that the speech belongs less to the president and more to the country.

5

Enjoy a simple breeze

Picture the president’s reaction on his first day of office when he is advised that he is prohibited from opening windows. The White House and presidential vehicles keep their windows sealed to prevent the president from being attacked.

Michelle Obama once shared that there was one small break from those strict rules . During a short drive to Camp David, her Secret Service agent allowed her to open the car windows for a few minutes. She later described it as a feeling of normal people's luxury.

6

Block followers from official pages

What about the president’s digital life? Technology advances quickly, and presidential security must keep up; presidents cannot simply use personal social media without being monitored. In 2018, a federal judge ruled that a president cannot block people from official social media spaces, because those accounts can be treated as public forums. So even online, presidents have some restrictions to follow.

7

Hit the road by themselves

While in office, presidents and vice presidents are not allowed to drive on open roads. What’s more, the Secret Service must control their transportation in real time . There are some exceptions, though: inside personal properties, and in places like Camp David, they can drive, walk, and even ride a bike.

8

Throw away their own papers

Presidents also cannot treat their office like a normal workspace. Under the Presidential Records Act, letters, notes, and emails may count as official records. That means presidents are discouraged from simply cleaning up or throwing mail away on their own. Instead, White House staff must sort everything carefully first, so no important piece of history ends up in the trash by accident.

9

Join normal family outings

Imagine the scene of the president casually arriving at his child’s school one morning. As we would assume, there are security restrictions that prevent presidents from attending a child or grandchild's concert or sporting event. These restrictions affect the entire First Family, but they also keep everyday situations from turning chaotic.

10

Scroll through a normal inbox

Even the president’s inbox has personal security. People can send a message to the president online, but it does not go straight to a personal email account; it actually goes through the official White House contact form first. Then staff members read it, sort it, and decide where it should go. Since presidential emails can become part of the public record, they must be saved and handled carefully.
