$125 million for a Grade-school math error

Imagine losing a hugely expensive spacecraft due to a simple mix-up between English and metric measurements . That is exactly what happened to NASA in 1999 when a Mars orbiter designed by Lockheed Martin was lost in space.

The confusion caused a malfunction on the $125 million craft, resulting in the probe’s loss. Although it was unusual for Lockheed to use English measurements for a NASA design (since NASA had stipulated using metric measurements for many years), there were still several instances where the error should have been caught but wasn’t.

Toys ‘R’ Us blunder

If you think an action figure of a drug dealer isn’t the best idea for a toy store , you’re not alone. Yet, for some reason, Toys "R" Us decided otherwise in October 2014, possibly hoping to cash in on the massive success of the Breaking Bad TV series.

Unsurprisingly, the giant toy retailer was forced to pull from its shelves four collectible dolls based on characters from the AMC hit show, each doll featuring a detachable sack of cash and a bag of meth.

Apple Maps' rocky beginnings

When Apple decided to launch its own map application on iOS devices after a conflict with Google in 2012, users quickly realized that the Apple app was not nearly as launch-ready as it should have been .

Locations were mislabeled, roads were missing, and it occasionally steered people in entirely the wrong direction. The problem was eventually, though largely, resolved, but it was an embarrassing misstep for a company known for never launching a product before it was as near-perfect as possible.

Bank of America debit card fee

Image: Ali Mkumbwa

Back in 2011, when the backlash against the banking industry had not yet reached its boiling point, Bank of America announced it would charge customers $5 per month to use their debit cards .

It was a bad business decision. More than 300,000 people signed an online petition, and Fox Business Network’s Gerri Willis cut up her debit card on air. The bank pointed to federal regulations as the reason for the charge but ultimately capitulated to consumer demand after a month before the fees went into effect.

$33 airline tickets from Toronto to Cyprus

If buying a business class ticket regularly priced at $2,558 for just $33 sounds too good to be true, it probably is. Except in 2006, when an Alitalia employee accidentally forgot to input two extra zeros when pricing business-class tickets from Toronto to Cyprus.

Due to the exchange rate on that day and the blunder, hundreds of buyers managed to snag fares for just $33. The airline honored those deals, accepting the heavily discounted price for the 509 people who purchased tickets before the error was detected.

A $70 million comma

As the folks at NASA and Alitalia have shown us, small errors can lead to costly mistakes. The following blunder comes courtesy of Lockheed Martin , which issued a contract to a customer with a missing comma in the sale price .

The astute customer held the aerospace company to the contract, costing Lockheed Martin $70 million for a C-130J Hercules aircraft in June 1999.

Sears misses the ship

A retail giant that faced a situation similar to the one Kodak faced—embrace the new and unknown or cling to the old, successful recipe—Sears sold everything from socks to tires via mail order, shipping across the U.S.

Choosing to stick with the old method, the company ended its catalog and delivery business in 1993 . In 1994, Amazon was founded , filling the business void that Sears had just created. The rest is history.

Passing on Microsoft

Image: Jaime Marrero

$60 million might seem like a lot of money to us regular folks, but for someone with very deep pockets like Texas businessman and two-time U.S. presidential candidate Ross Perot, it wasn’t all that much.

In 1979, he was offered the chance to buy Microsoft for that sum. However, his final offer to the tech company was just $15 million, and as a result, the Texan missed out on the opportunity to own what would become one of the biggest companies in the world .

Blackberry sticks with the old

Another case of a brand sticking with the old instead of embracing the new, BlackBerry was all the rage at the start of the 21st century— until Steve Jobs came along with the Apple iPhone .

While BlackBerry Messenger was extremely popular, with over 80 million users worldwide, the device lacked the new touchscreen functionality and sleek design of the Apple product. From being a market leader, BlackBerry’s market share plummeted to 0.2% by 2016.

RadioShack’s downfall

Image: Jelleke Vanooteghem

Not so long ago, RadioShack was a familiar presence on the streets and the go-to place for buying batteries and electronics. But it was that same brick-and-mortar presence, coupled with a reluctance to embrace e-commerce , that ultimately led to its demise .

Eventually, poor profit margins on what they could sell, combined with a loan they couldn’t repay, brought down what was once the go-to place for electronics.

Harriet Tubman secretly worked as a Union spy

Most Americans know Harriet Tubman for her leadership of the Underground Railroad, but during the Civil War, she also became a Union scout and spy in South Carolina. Working with Colonel James Montgomery, Tubman gathered intelligence from enslaved people living behind Confederate lines near the Combahee River .

In June 1863, Tubman helped lead the Combahee River Raid, guiding Union gunboats through Confederate waters filled with hidden mines. The operation freed more than 700 enslaved people and made Tubman the first woman known to lead a major U.S. military mission.

2

Julia Child worked for the U.S. intelligence agency

Before becoming television’s most famous chef, Julia Child joined the Office of Strategic Services, or OSS, in 1942 during World War II. The OSS later evolved into the CIA. Too tall to enlist in the Women’s Army Corps, Child instead classified files and overseas communications in Asia.

One of her strangest assignments involved helping researchers develop shark repellent for Navy explosives and emergency rescue kits . The repellent used copper acetate and black dye to create an odor similar to a dead shark.

Benjamin Franklin conducted unofficial spy work in Europe

Benjamin Franklin was more than a scientist and Founding Father. During the American Revolution, he quietly acted as an intelligence organizer while serving as ambassador to France beginning in 1776 . Franklin cultivated secret alliances, intercepted information, and used coded correspondence to support the colonies’ fight against Britain.

Operating from Paris, Franklin built relationships with French officials and helped persuade France to support the American cause with money, troops, and naval power. Historians consider his diplomatic intelligence efforts essential to the American victory at Yorktown in 1781 and eventual independence.

Louisa May Alcott published thrillers under another name

Louisa May Alcott became a literary icon after publishing Little Women in 1868, but few readers knew that she had already written sensational thrillers under the pen name "A.M. Barnard." These stories featured revenge, hidden identities, forbidden romance, and dramatic crime plots that shocked Victorian audiences.

Alcott used a pseudonym because publishers often expected women writers to produce respectable domestic fiction. Many of her darker stories remained forgotten until scholars rediscovered them in the 1940s. Today, titles like Behind a Mask reveal a far more rebellious side of the beloved author.

Maya Angelou worked as San Francisco’s first black female cable car conductor

Long before becoming a celebrated poet and author, Maya Angelou made history in San Francisco during the 1940s. At only 16 years old, she applied repeatedly for a conductor job on the city’s cable cars after seeing an advertisement that excluded Black applicants .

Angelou refused to give up despite repeated rejection. She eventually became San Francisco’s first Black female cable car conductor in 1944. Years later, she described proudly wearing the blue uniform while working long shifts across the city before launching her writing and civil rights careers.

Dr. Seuss created classified wartime propaganda films

Before writing Green Eggs and Ham and The Cat in the Hat , Theodor Geisel, better known as Dr. Seuss, worked on wartime propaganda during World War II. Between 1943 and 1945, he joined director Frank Capra’s Signal Corps unit to produce military training films for American soldiers .

Geisel also drew political cartoons supporting the Allied war effort and criticizing fascism. Some of his films were classified during the war because they contained military training material. His animated work helped explain battlefield strategy and morale issues to thousands of U.S. troops overseas.

Babe Ruth once played an entire game with a fever over 102 degrees

In 1925, Babe Ruth became seriously ill during spring training and collapsed while traveling by train . Newspapers nicknamed the incident "the bellyache heard around the world." Reports from the time described Ruth suffering from a fever above 102 degrees while still insisting on returning to baseball activities.

Despite his condition, Ruth’s determination became part of baseball legend. The illness hurt his performance during the 1925 season, when the New York Yankees finished seventh in the American League. Even so, Ruth rebounded quickly and helped lead the Yankees to championships in later years.

Harry Houdini worked with police departments

Harry Houdini’s famous escape acts fascinated police departments across America and Europe in the early 1900s. Officers regularly challenged him to escape from handcuffs, prison wagons, and locked jail cells. Houdini often invited local police to inspect restraints before his performances began.

Beyond entertainment, Houdini also worked closely with law enforcement to expose fraudulent mediums and fake spiritualists during the 1920s . Using his knowledge of locks, hidden compartments, and deception, he publicly demonstrated how many supposed supernatural tricks were actually carefully staged illusions.

Frank Lloyd Wright hid a private apartment inside one of his buildings

Architect Frank Lloyd Wright secretly maintained a private apartment inside his famous Oak Park Studio near Chicago, Illinois. Built in the 1890s, the studio served as both his workplace and personal retreat while he designed many of his early Prairie-style homes across the Midwest.

The hidden living quarters allowed Wright to work late into the night and host select guests away from public attention. The building itself became one of the most important centers of American architecture, producing groundbreaking residential designs that influenced modern architecture around the world.

Muhammad Ali quietly funded humanitarian causes for years

Muhammad Ali’s boxing fame often overshadowed his enormous charitable work. For decades, Ali quietly donated money to hospitals, food programs, children’s charities, and international humanitarian efforts . Friends and family later revealed that many of his contributions were intentionally kept private.

In 1990, Ali traveled to Iraq during tensions leading up to the Gulf War and helped secure the release of 15 American hostages. He also supported global relief organizations and Parkinson’s disease research after his own diagnosis. In 2005, President George W. Bush awarded Ali the Presidential Medal of Freedom.

Apple pie

We’ll start with an undisputed American icon: After all, doesn’t the saying go, "as American as apple pie" ? This iconic treat has been at the heart of countless American traditions, perhaps most notably during Independence Day celebrations. Fireworks and a slice of apple pie are all we need for a 4th of July to remember.

While apple pies originated in 14th-century England, it wasn’t until they arrived in America that they became a global icon. Over the centuries, several recipes and toppings have emerged, such as whipped cream, ice cream, custard, or even cheddar cheese.

Key lime pie

Who says pies can’t be sour? The Key Lime Pie is the perfect example of a " When life gives you lemons " mentality: it takes the lime, a fruit that no one would want to eat raw, and transforms it into a luscious and delicious treat.

The Key Lime Pie is Florida’s official state pie, as it was invented in the "Sunshine State" during the 1940s. Not only that, but the traditional way to make this pie uses Key limes, which get their name from the Florida Keys where they are grown.

Blueberry pie

Just like pumpkin pies, blueberry pies were first created by American settlers , who used the abundant varieties of blueberries found in the country to make these delicious treats. Over time, their popularity spread to Europe, where people used their own types of blueberries to try to replicate the American versions.

This sweet treat has become synonymous with the state of Maine, where blueberry pie made with wild Maine blueberries was designated as the official state dessert. However, blueberry pie is still happily enjoyed across the entire nation.

Pumpkin pie

Just like apple pie is the go-to dessert for the 4th of July, pumpkin pie is instantly associated with Thanksgiving . After all, the origins of this delicious treat can be traced back to the very first American colonists, though it was served in a very different manner. Historians believe that these early versions of pumpkin pie were more akin to a type of pumpkin soup, served inside a hollowed-out pumpkin.

Nowadays, the pumpkin pie we know and love is made with eggs, milk, evaporated sugar, and several spices like nutmeg, ginger, and cinnamon, often topped with a generous dollop of whipped cream.

Boston Cream pie

Image: Marko Klaric

According to some historians, Armenian-French chef Mossburg Sanzian created a particularly delicious cream-filled cake one afternoon in 1856 at the Parker House Hotel in Boston. Unbeknownst to Sanzian, his creation would eventually become the iconic Boston cream pie , declared Massachusetts’ official state dessert in 1996.

Since that day in 1856, this iconic dessert has gone by many names, such as "chocolate cream pie" and "Parker House chocolate cream pie." You might be confused by our use of the word "cake," but that was no mistake: The Boston cream pie is technically a cake. Its confusing name comes from the fact that, in the 19th century, both cakes and pies were baked in the same pan, which led these two words to become synonyms.

6

Peanut Pie

American President James "Jimmy" Carter is still well-known for his love of peanuts, so it stands to reason that his beloved wife, Rosalynn, was known for her delicious peanut pie . After all, this pie is a staple of Southern cuisine and is especially beloved in Carter’s home state of Georgia.

Peanut pie is similar to pecan pie in that they are prepared with similar ingredients, such as corn syrup, eggs, and sugar. However, peanut pie is highly versatile and may include other ingredients, such as molasses, cayenne pepper, bourbon, or cream cheese.

Marionberry Pie

The marionberry pie is a delicious treat, particularly popular in the Pacific Northwest. After all, this type of blackberry is named after Marion County in Oregon , where it was bred and tested during the 20th century.

As you would expect, the marionberry pie is Oregon’s official state pie, and it truly shows. If you ever happen to visit "The Beaver State" during berry season, you’ll probably be welcomed with a warm smile and a slice of delicious marionberry pie.

Peach cobbler

Image: khezez | خزاز

Cobbler is definitely the entry with the most baffling name on this list. After all, what does a shoemaker have to do with this delicious dessert? In any case, don’t let this unusual name discourage you; cobblers are a simple yet amazing sweet treat.

While we would love to include as many types of cobblers as we could find, for brevity's sake, we’ll instead focus on one of the most popular cobblers in America: Peach cobbler combines the sweetness and texture of peaches with a crumbly, sweet topping. In 2013, Texas declared the peach cobbler its official state cobbler.

Pecan pie

Standing on the other side of peanut pie, we have pecan pie, another Southern delicacy . Just like peanut pie, pecan pie might seem simple at first glance, but there are several variants and styles associated with this sweet treat. Different recipes include molasses, honey, or cane syrup.

In the American South, pecan pie is closely associated with the holidays, especially Thanksgiving and Christmas. Due to its status as a cultural icon, Texas declared pecan pie its official state pie.

10

Cherry pie

Image: Nik

While most of us associate the 4th of July with apple pie, it should also be noted that many Americans picture a delicious slice of cherry pie when reminiscing about our Independence Day. Like many other pies on this list, cherry pie can be enjoyed with whipped cream or ice cream.

Cherry pie is also deeply ingrained in American folk songs , such as "Billy Boy," where the titular character is asked whether his bride-to-be can cook a cherry pie. Additionally, cherry pie is linked to George Washington’s birthday, thanks to the popular legend of a young Washington chopping down his father’s cherry tree.
