$125 million for a Grade-school math error

Image: Aaron Lefler

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.

The disappearance of Amelia Earhart (1937)

The first entry on our list is dedicated to a world-renowned flight pioneer, Amelia Earhart, who vanished while attempting to become the first woman to fly around the globe , leaving behind only fragments of her plane and endless speculation. Radio failure, poor visibility, and fuel issues are speculated to be contributing factors to her disappearance.

Even with modern technology and repeated searches, no one has ever found definitive proof of what happened to Amelia or her aircraft.

2

The D.B. Cooper hijacking (1971)

In 1971, Dan Cooper, a seemingly quiet man, boarded a plane in Portland, Oregon, which he promptly hijacked when the aircraft was in the air. He demanded $200,000 over the radio.

The plane landed in Seattle, where authorities met his demands. Cooper released all 36 passengers in exchange for the cash and parachutes. He then ordered the remaining crew to fly toward Mexico City at a low altitude and slow speed. Somewhere over southwest Washington, he lowered the aircraft's aft stairs and jumped into the freezing night, never to be seen again.

3

The disappearance of Jimmy Hoffa (1975)

The powerful union leader left a Detroit restaurant in 1975 and simply vanished . Witnesses last saw him standing by his car in the restaurant’s parking lot, and investigators believe he was coaxed into a car by people he recognized, thinking the meeting location had changed. He was never seen again. Searches in fields, lakes, and construction sites turned up nothing. To this day, it remains one of the most famous unsolved mysteries in American history.

Rumors range from mob connections to government cover-ups, but none have been proven. Ever since then, Hoffa’s name has become shorthand for anything that disappears without a trace.

4

The Yuba County Five (1978)

In what came to be known as "America’s Dyatlov Pass", five friends vanished after attending a basketball game in the town of Chico, California. Months later, the bodies of four members of the group were found in the mountains under mysterious conditions .

The remaining member of the original party was never located, and their strange route into deep snow remains unexplained.

5

The Sodder Children (1975)

A fire destroyed the Sodder family home in West Virginia, but five children were never found among the remains of the house. Because of physical inconsistencies at the scene and strange sightings afterward, the family always believed they survived.

Over the years, strange sightings and letters fueled hope and confusion alike, but no real evidence has ever been found. Because of these clues, the Sodders never held a funeral and instead famously erected a billboard on Route 16, offering a reward for information and keeping the case in the public eye for decades.

6

The Springfield Three (1992)

On a warm summer night in 1992, Sherrill Sherrill Levitt, her daughter Suzie, and Suzie's friend Stacy vanished from their home in Springfield, Missouri, leaving behind their cars, purses, and even the family dog .

Friends arriving the next morning found the house empty but unlocked. Despite thousands of leads, no evidence or remains have surfaced. The case remains one of the most talked-about disappearances in small-town America to this day.

7

The Gardner Museum Heist (1990)

Back in 1990, two men dressed as police officers entered Boston’s Isabella Stewart Gardner Museum and stole 13 works of art worth over $500 million .

No piece has ever been recovered. Empty frames still hang on the museum walls, a quiet tribute to one of history’s most expensive thefts.

8

The Max Headroom broadcast hijack (1987)

1980s television viewers might remember Max Headroom as a somewhat clumsy computer AI TV personality and ad spokesperson. In 1987, Chicago viewers were startled when a strange figure wearing a Max Headroom mask interrupted TV broadcasts with odd messages .

The stunt lasted only seconds, but no one was ever caught or identified. It remains one of the strangest unsolved moments in television history.

9

The Great Lakes ghost ships

Over the years, s everal ships have vanished or been found adrift on the Great Lakes , their crews gone without explanation. Cold weather, sudden storms, and superstition all play roles in the stories, but some cases defy logic. The vast inland seas are simply too big to be accessible with the current technology.

Among the most notable unsolved cases, we can mention Le Griffon, a ship that vanished during her maiden voyage in 1679, the SS Banockburn, known as the "Flying Dutchman of Lake Superior," disappeared during a storm in 1902, or the SS Chicora, a luxury steamer lost in a violent winter gale while carrying a cargo of flour, in 1895.

10

The Dulce Base Mystery

Beginning in the 1970s, a constant array of strange lights, unmarked aircraft, and talk of secret tunnels near the town of Dulce has fueled decades of conspiracy theories in this otherwise quiet area to this day.

While skeptics blame radar tests or imagination, locals still report odd sightings in the desert skies.

Big Mac (McDonald's)

Two beef patties, shredded lettuce, dill pickles, onions, cheddar cheese, and a special sauce, all topped with two seeded buns. That's the Big Mac, McDonald's flagship product and one of the world's best-selling fast food dishes.

The idea of the Big Mac as we know it today was originally conceived in the mid-1960s by entrepreneur Jim Delligatti, owner of one of the brand's first franchises. The name of the iconic burger, however, was suggested by a 21-year-old secretary working in McDonald's advertising department.

Classic Pretzel (Auntie Anne’s)

If we talk about the best fast food snacks, pretzels must be included. In the United States, "pretzel" is synonymous with Auntie Anne's. This franchised chain, founded in 1988 , now boasts more than 1,300 stores across the country.

Curly fries (Arby’s)

Fries never disappoint, but if they come in a novel spiral shape, well-seasoned, and perfectly sized to devour in one bite, we're looking at one of the most incredible fries ever created.

While Arby's may not have invented curly fries, it was certainly the company that brought them to fame. Arby's introduced these crispy and delicious Cajun-style seasoned fries in 1988, and they have been a hit ever since.

Chicken tenders (Popeyes)

Many fast food chains offer their version of the chicken nugget, but since Popeyes specializes in fried chicken, it's no surprise that they have one of the best versions of chicken tenders on the market.

Krispy Kreme has been around since 1937, and in those many years of history, it has created hundreds of different doughnut flavors. Yet, the glazed doughnut remains a classic that never fails to impress.

Its light, fluffy, melt-in-your-mouth texture paired with that crackly glaze transports anyone back to their childhood in an instant—especially if you're lucky enough to get them fresh out of the oven!

7

Fried chicken (KFC)

One of Popeyes' biggest competitors is, without a doubt, Kentucky Fried Chicken. While Popeyes is known for its chicken tenders, KFC is famous for its giant buckets of fried chicken.

KFC's signature dish is fried, on-the-bone chicken pieces seasoned with Colonel Harland Sanders' "Original Recipe" of 11 herbs and spices—and we all love it. Whether you have them at a Fourth of July celebration or during a football game, KFC's fried chicken has that nostalgic effect that keeps you going!

Whopper (Burger King)

If there's one thing we've always associated with Burger King, it's that distinctive grilled flavor. And the best representation of that flavor is its signature dish, the Whopper burger.

Although the ingredients of this gigantic sandwich, created in the late 1950s , are quite simple—one beef patty, lettuce, tomato, and pickles—it’s a favorite among fast food lovers around the world.

Italian B.M.T. (Subway)

Subway is one of the largest fast-food chains in the world, specializing in submarine sandwiches. While everyone can create their own custom sandwich with fresh ingredients of their choice, Subway has a best-selling sandwich that has become an all-time classic.

Subway's Italian B.M.T.—short for "Biggest, Meatiest, Tastiest"—is served on freshly baked bread and filled with a combination of three types of deli meats: salami, pepperoni, and ham. According to lore, the name also references the Brooklyn-Manhattan Transit subway line. Did you know that?

10

Blizzard (Dairy Queen)

Image: ROMAN ODINTSOV

A list of the best fast food items wouldn't be complete without including at least one ice cream product. Many chains offer incredible alternatives, but Dairy Queen is, well, the queen of soft serve.

Dairy Queen's staple product, the Blizzard, was introduced in 1985 , and that same year, the company sold more than 100 million desserts. Today, there are almost 20 different Blizzard flavors, each with the best toppings. From cookies to candy, there's a delicious option for everyone!

11

Baconator (Wendy’s)

Wendy's is an American fast-food restaurant, founded in 1969, famous for its square patties. It offers a large number of products, all equally delicious. But even though it was only introduced in 2007, the Baconator has become one of its flagship products, helping the company increase its sales.

A perfect combination of beef, American cheese, and crispy smoked bacon makes this burger a favorite among consumers across the country.

Onion rings (Burger King)

French fries are the ultimate fast food side dish, but every once in a while, it's nice to switch things up and try something new. Burger King's onion rings are definitely a safe bet.

Tender and sweet on the inside, and crunchy on the outside, this classic American treat consists of sliced onions covered in batter and breadcrumbs, then deep-fried. Overall, it's the perfect snack for dipping into your favorite sauce!
