$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

Image: Estefania Cortes

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

Image: Thai Nguyen

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.

Legal drinking age

Image: Elevate

When was the first time you tried a beer? Probably at 21 or later. While that's completely normal here in the US, it can seem a bit strange to people in other parts of the world. Why? In America, you can vote, serve on a jury, and even get married in some states at 18, but you still can't legally buy alcohol until you're 21. In many other countries, the legal drinking age is 18—or even younger—and that's why they find our law unusual.

2

The faces of real estate agents

Image: Tierra Mallorca

We're used to walking through a neighborhood and seeing signs with real estate agents' faces in front of homes for sale. But in other countries, that's pretty unusual! In many places, real estate transactions are more impersonal; you deal with an agency, not a specific person. Here in the US, we like to put a face to the name. Getting to know the person helping you buy or sell a home feels more personal and trustworthy. It makes sense, right?

3

Our coins

Image: Shot by Cerqueira

Many of us don't even notice this until we travel abroad, but some of our coins don't actually show their value! Sure, you'll see words like "Five Cents," "One Cent," or even "One Dime," but there's no actual number printed on them. When you think about it, that's kind of strange, right? Especially when most countries display the value on their coins using numbers.

4

American flag everywhere

Image: camera obscura

In many countries, their national flag is used only for formal or official purposes, but that's not the case in the US. We tend to see the American flag literally everywhere, not just at official functions or holiday celebrations, but also on all kinds of products and imagery. From T-shirts and caps to food packaging and even swimsuits, our flag is a constant presence in everyday life.

5

No bad words on TV

Image: Kevin Woblick

If you're in America and turn on your TV right now, you'll find everything from romantic scenes to shows about zombies or violent crimes, but you'll rarely hear any bad language. Our television generally doesn't include insults or swear words, while in other countries they often do, even in shows that air during times when children might be watching.

6

Dinner before 8 PM

Image: Or Hakim

Depending on the region, dinner in the United States is often served before 8 p.m., and sometimes even before 7 p.m. But in many other countries, that's considered too early. In Latin America, for example, most people eat dinner between 8 and 11 p.m.!

7

The Imperial System

Image: Jarosław Kwoczała

We Americans use miles, feet, pounds, and degrees Fahrenheit, but this is often very confusing for visitors from other parts of the world. We are totally used to the Imperial System, but in most countries, the Metric System reigns supreme, with everything measured in meters, kilometers, kilograms, and degrees Celsius.

8

Big portions

Image: mafe estudio

Large portions are deeply ingrained in our daily lives. Whether it's restaurant meals, snack packs, or soft drinks, everything tends to be bigger in America. This can be surprising for foreigners who come here and order food, since in many other countries, dishes are smaller, and the custom of taking leftovers home after eating at a restaurant isn't as common as it is in the US.

9

Turkey pardon

Image: Tyler Donaghy

The pardoning of the turkey by the US president is a big event for many Americans. But in other parts of the world, where Thanksgiving isn't celebrated, it can come as a surprise. To foreigners, this formal ceremony involving a turkey might seem quite strange. Since Thanksgiving traditions aren't part of their history, this custom is uniquely American.

10

Alumni homecoming

Image: Carol Highsmith's America

Perhaps you've had the chance to participate in Homecoming, the annual event that celebrates university spirit with parties, sports games, and other activities for students returning to campus. While it's a big part of our college tradition and communities are deeply involved, it's quite different in other parts of the world, where the return to school usually happens with little fanfare.
