History is a funny thing. There’s so much of it that we just don’t know anything for sure. Sometimes, truly artful frauds and forgeries have emerged to put historians and scholars in their place. These deceptions have been especially costly, both financially and in terms of setbacks to archaeological knowledge. Below we dive into the ten most infamous and expensive archaeological forgeries that left a lasting mark on the field.

1 Brigido Lara’s Pottery

When Brigido Lara was convicted of looting some of Mexico’s most valuable antiquities, he turned the tables with an unexpected defense: he claimed he was not a thief but a forger. While incarcerated, Lara demonstrated that the artifacts in his possession were his own creations by producing additional pieces and presenting them to the same experts who had previously authenticated the originals.

Further investigation revealed that Lara had been crafting replicas for over two decades, producing thousands of items that he considered original artistic interpretations rather than mere copies. His oeuvre spanned styles of the Maya, the Aztec, and most notably the Totonac civilization, which flourished from the 7th to the 12th centuries. Arrested in July 1974 and released by 1975, his talent secured him a museum position, yet it also made many parties uneasy.

Employed by the Xalapa Anthropology Museum, Lara was permitted to continue his work. Although his pieces were signed and clearly marked as reproductions, it gradually emerged that an estimated 40,000 of his creations had already entered the market, with museums and private collectors spending fortunes on them. Lara’s “original interpretations” ended up on display at the Metropolitan Museum in New York, the Saint Louis Art Museum, and in high‑value private collections. When the governor of Veracruz attempted to repatriate native artifacts by purchasing a major collection from Sotheby’s, Lara informed him that the lot consisted entirely of his own forgeries. Ironically, much of what scholars believe they know about the Totonac culture stems from the study of Lara’s fabricated pieces.

2 Drake’s Plate

The legend says Sir Francis Drake stopped in a California bay in June 1579, and while his ship was being refitted, he commissioned a brass plaque to mark the claim of the land for his queen. Supposedly discovered in 1936, metallurgical analysis supported its authenticity, and the plaque was acquired by the Bancroft Library at the University of California, Berkeley.

This turned out to be a classic case of a forgery spiraling out of control. For decades, scholars debated its legitimacy until 2003, when the truth emerged: the plate was fabricated by members of the California Historical Society, an art dealer, and an engraver, specifically to deceive Herbert Bolton, the library’s director and a member of the society. Bolton, obsessed with locating the artifact, had been urged by colleagues to fulfill his dream.

Using text from a 1628 account of Drake’s voyages, the conspirators forged, chiseled, heated, and aged the plaque. They even painted the letters “ECV” in fluorescent paint on the reverse, intending it as a prank. Before they could confess, the forgery passed expert scrutiny, and Bolton, along with historical society president Alan Chickering, paid $3,500 for it. Because the conspirators were part of a tight‑knit professional circle, a confession proved difficult, allowing the fake to sit proudly in the library for decades. It wasn’t until the death of the involved parties that Lorenz Noll, an art dealer, signed an affidavit in 1954 declaring the plate a fake. By then, the hoax had ignited a 50‑year archaeological debate about Drake’s route and even featured in the 1939–40 Golden Gate International Exposition.

3 Charles Dawson’s List Of Fakes

Charles Dawson is most famously linked to the Piltdown Man. In 1912, the amateur archaeologist announced the discovery of a skull he believed to be the elusive “missing link.” It wasn’t until 1949 that further testing revealed the skull was a composite of a modern human cranium and an orangutan’s jaw, dramatically setting back British paleontology.

The true forger behind Piltdown remains debated, but Dawson’s involvement is widely acknowledged. Yet many scholars argue he could not have executed the hoax alone, especially after his post‑mortem papers exposed a wider pattern of deceit. Dawson was later tied to 38 additional “artifacts,” ranging from ancient hammers and statuettes to axes and Roman tiles. Described as a serial forger and serial finder, he conveniently “discovered” many of his own fabrications, planting them for maximum impact.

Dawson’s mischief extended beyond archaeology: he fabricated records of rare bird sightings in Sussex, introduced bogus horse skulls with horn traces, invented a hybrid fish, claimed English Channel sea serpents, and even suggested rocks concealed petrified toads. Theories about the Piltdown hoax’s masterminds include Arthur Conan Doyle, seeking revenge against a secular scientific establishment; Martin Hinton of the Natural History Museum, who possessed materials similar to those used in the forgery; and Jesuit philosopher Teilhard de Chardin, who opposed excavations that contradicted religious narratives. Ultimately, Dawson’s legacy inflicted a heavy cost on British scientific credibility, though the forgery itself was not particularly sophisticated.

4 Archaeoraptor

The so‑called Archaeoraptor was “found” in 1999 and exposed as a hoax by Nature in 2002. The specimen, touted as a missing link between birds and dinosaurs, fetched $80,000 from an eager buyer before its true nature was revealed.

Originating from Liaoning Province, China, the fossil turned out to be a composite: the remains of a small, fish‑eating bird were glued to the bones of a diminutive dromaeosaur. Ironically, the two species used in the forgery were the first known examples of each, suggesting the forgers deliberately selected iconic specimens. The fossil’s provenance from a region renowned for bird‑dinosaur transitional fossils lent it credibility.

Archaeoraptor is one of many fossils illicitly exported from China, where strict laws prohibit such trade. The black market thrives, and some argue that the forgers—often underpaid workers—glued ancient bones together not purely out of deceit but to survive financially. This ethical gray area forces paleontologists to scrutinize all Chinese fossils with heightened skepticism.

5 The Etruscan Warriors

In 1961, the Metropolitan Museum of Art in New York reluctantly admitted that three life‑size Etruscan warrior statues on display were forgeries. While the pictured statue is authentic, the others were fabricated by Italian forgers Riccardo Riccardi and Alfredo Fioravanti, who continued a centuries‑old tradition of terra‑cotta counterfeiters that began with the Pirelli family.

The forgers set up a studio near a plausible excavation site, producing terra‑cotta plaques that were marketed as artifacts from a mysterious Italian temple. Lacking a kiln large enough for full‑size statues, they broke the pieces before firing, later attributing any damage to age. After painting the fragments, they sold the assembled, brightly colored statues to the Met.

Critics had long suspected the statues were fake, noting that the vivid pigments were inconsistent with ancient materials and that a single piece could not have been fired whole. In 1955, a skeptic claimed the statues were made from ground‑up beer bottles—a claim later disproved. Extensive testing finally confirmed that the statues could not have been produced as a single piece and that the paints were modern, confirming the forgers’ deception.

6 Moses Shapira And Deuteronomy

Moses Shapira began his career as a reputable antiquities dealer, trusted by museums in England and Germany for sourcing rare texts. By 1883, the British Museum regularly procured artifacts from him. However, that July, Shapira presented scholars with a manuscript he claimed was a previously unknown version of Deuteronomy, composed of 15 parchment pieces.

Experts quickly denounced the scroll as a fraud, accusing Shapira of merely translating a modern text onto ancient‑looking parchment. Shapira blamed biblical scholar Christian Ginsberg and other experts for ruining his reputation, and six months later he took his own life. The manuscript, initially offered for £1 million, sold at auction after his death for a few shillings.

Shapira asserted that Bedouins had supplied the parchment in 1878. While many believed the climate of the region would have destroyed such a document, the later discovery of the Dead Sea Scrolls proved ancient parchments could survive. German scholars first labeled the manuscript a forgery, a verdict reinforced by French archaeologist Clermont‑Ganneau, who had previously exposed Shapira’s involvement in other counterfeit artifacts. By the time Ginsberg publicly declared the scroll fake, Shapira’s reputation was irrevocably tarnished, and the manuscript vanished from public view. Whether Shapira was the genuine forger or a victim remains unresolved, though records suggest he sold over 1,700 forged items to the Berlin Museum in the 1870s.

7 Lead Books Of Sacromonte

Between March 1588 and April 1595, 22 lead tablets were unearthed in the hills surrounding Granada, Spain. Inscribed in Arabic and translated by church officials, the plates purportedly contained Christian texts, including a letter from San Cecilio, Granada’s patron saint, and prophecies attributed to John the Baptist.

Initially displayed publicly, the tablets soon attracted skepticism. Over the next 150 years, debate persisted until the Vatican, in 1682, officially condemned the plates as containing false doctrine. Forgotten for centuries, the tablets resurfaced in 1999, were returned to Granada in 2000, and reignited scholarly curiosity.

Most scholars now agree the lead books were not contemporary with San Cecilio’s first‑century mission. The prevailing theory holds that Morisco exiles—Muslim Spaniards expelled during the Reconquista—fabricated the tablets to bridge Christian and Muslim narratives. Researchers point to two Morisco scholars, Miguel de Luna and Alonso del Castillo, as likely authors. Their text deliberately blends Christian and Islamic motifs, referring to Jesus as “the spirit” rather than the Son of God, aiming to create a syncretic document that could appease both faiths. The tablets remain housed at the Abbey of Sacromonte in Granada.

8 Eugene Boban And The Crystal Skulls

The myth of crystal skulls has long captivated both believers and skeptics. Central to the controversy is French antiquarian Eugene Boban, who spent two decades in Mexico before returning to France, claiming to have sourced authentic pre‑Columbian artifacts for exhibition.

Boban’s sales catalogues reveal a seasoned dealer familiar with archaeological sites, yet they also list items he openly labeled as fakes, offering them for study to expose fraudsters. Among his most infamous offerings was a large crystal skull, which he attempted to sell to the Smithsonian despite warnings that he could not be trusted.

Boban’s relentless promotion of the skulls eventually led to one entering the British Museum, though the National Museum of Mexico declared it an outright forgery. He was also linked to a series of smaller skulls, about five centimeters tall, further cementing his reputation as a key figure in the heated debate over the authenticity of these enigmatic artifacts.

9 George Hull And Solid Muldoon

George Hull is best remembered for the Cardiff Giant, a fabricated petrified man that captivated 19th‑century America. In 1876, Hull attempted a second hoax in Colorado, creating the “Solid Muldoon,” a clay‑and‑plaster figure unearthed in Beulah, Colorado, in September 1877.

Hull added theatrical touches: the figure’s head snapped off, revealing what appeared to be vertebrae, and a monkey’s tail was attached, prompting claims that the specimen represented both a giant and the missing evolutionary link. Suspicion grew when observers noted the absence of a genuine excavation pit. The famed showman P.T. Barnum soon partnered with Hull, investing $15,000 and taking a 75 percent share of profits. The hoax persisted until a collaborator exposed the fraud, ending the public’s fascination.

10 The Kinderhook Plates

When Joseph Smith announced he had translated the golden plates forming the foundation of Mormonism, skeptics responded by creating their own set of forgeries: the Kinderhook Plates. Discovered in 1843 in Kinderhook, Illinois, the six plates bore mysterious characters and were allegedly found alongside a giant’s skeleton.

Smith reportedly translated part of the plates, claiming they identified the discoverer as a descendant of Ham and contained a family history. For decades, the plates were accepted as genuine until forensic analysis in 1980 proved the surviving plate was a 19th‑century creation.

The deception was traced to William Clayton, Smith’s secretary, whose notes had been taken as proof of translation. Once the plates were exposed as fakes, scholars questioned Clayton’s credibility, suggesting he either misinterpreted Smith’s words, recorded them incorrectly, or fabricated the translation entirely. Today, most scholars agree Smith never truly translated the Kinderhook Plates, recognizing them as a historical hoax.

These ten costly archaeological forgeries not only drained fortunes but also reshaped scholarly discourse, reminding us that the pursuit of ancient truth can sometimes be clouded by human ambition and deception.

When you hear the phrase “10 costly mistakes,” you might picture a simple slip‑up, like spilling coffee on a shirt. In reality, overlooking a tiny detail can trigger a chain reaction that drains fortunes, shatters careers, and even ends lives. Below, we count down the ten most eye‑opening blunders where a missed detail turned into a multimillion‑dollar disaster.

1 Andres Escobar Was Killed For Scoring A Goal On His Own Team

Professional athletes constantly juggle pressure and public scrutiny. In 1994, Colombian midfielder Andrés Escobar unintentionally netted an own‑goal during the World Cup, a blunder that cost his team a crucial match and sparked fury among fans. The mistake ignited a wave of anger that culminated in a brutal attack: a group of men confronted Escobar on a street, initially mocking his error before one of them drew a gun and shot him six times. Though investigators suspected a drug‑linked patron who had lost money on the match, the case never proved a direct financial motive. Still, the tragedy underscores how a single lapse on the field can have fatal consequences off it.

2 William Shanks Wasted Years Incorrectly Calculating Pi By Hand

Before supercomputers could churn out trillions of digits, mathematicians tackled pi the old‑fashioned way: pen, paper, and relentless patience. English mathematician William Shanks, born in 1812, devoted decades to extending pi’s known digits. By 1873 he claimed to have reached a staggering 707‑digit stretch, a monumental achievement at the time. Yet a later review exposed a fatal slip at digit 527, meaning the last 180 digits were wrong. Shanks’ painstaking effort, once celebrated, was rendered essentially useless—a stark reminder that even the most diligent calculations can crumble from a single oversight.

3 Steve Rothstein Cost American Airlines $21 Million In Unlimited Flights

Promotional gimmicks can backfire spectacularly. American Airlines once rolled out an “AAirPass” for a flat $250,000, promising unlimited flights. The company assumed only a handful would abuse the offer, but Steve Rothstein seized the loophole, logging over 10,000 flights—often first‑class, sometimes just for a sandwich. He even booked strangers, fabricating companion names to maximize usage. The airline estimated the extravagance cost roughly $21 million before terminating his pass on fraud grounds. This case illustrates how a seemingly clever marketing move can become a colossal financial drain when the fine print is overlooked.

4 A Boy Tripped And Punched A Hole In A $1.5 Million Painting

Comedy often thrives on pratfalls, but when a 12‑year‑old visitor to Taipei’s Huashan 1914 Creative Arts Center stumbled into a priceless masterpiece, the joke turned costly. The exhibit featured “Flowers” by Paolo Porpora, a 17th‑century painting valued at $1.5 million. As the boy rushed toward the canvas, he tripped and instinctively thrust his hands forward, punching a gaping hole right through the artwork. Though insurance covered restoration, the incident highlighted the importance of protective barriers—whether glass or a simple rope—to safeguard irreplaceable art from accidental damage.

5 NASA Accidentally Sold A Bag That Had Been On The Moon

A quirky auction snafu turned into a multimillion‑dollar saga. In 2015, NASA’s surplus inventory was listed on eBay, where an Illinois collector purchased a white bag for just under $1,000, believing it to be a generic space‑flight souvenir. Unbeknownst to her, the bag had actually flown aboard Apollo 11, used to gather the first lunar dust samples. NASA, after realizing the mix‑up, refused to return the artifact, claiming it belonged to the American people and offered a refund instead. A lawsuit ensued, and a judge ruled in the buyer’s favor, leading her to resell the bag in 2017 for a jaw‑dropping $1.8 million. This episode underscores how a simple cataloging error can generate a fortune.

6 Astronaut Alan Bean Ruined Apollo 12’s Camera

When Apollo 12 set out for the Moon, the mission’s visual record depended on delicate film cameras. Astronaut Alan Bean, perhaps too eager to capture the lunar landscape, pointed his Hasselblad directly at the Sun. Without Earth’s atmospheric filter, the intense solar glare fried the camera’s sensor, rendering it inoperable after only a few shots. The loss forced the crew to rely on audio transmissions alone, dampening public enthusiasm and even causing TV networks to switch to soap operas during the broadcast. Bean’s simple oversight illustrates how a single mis‑aimed shot can jeopardize an entire mission’s documentation.

7 Soccer Fans Keep Mixing Up Bucharest And Budapest

Geographic literacy isn’t everyone’s forte, and a recurring mix‑up between Hungary’s Budapest and Romania’s Bucharest has left soccer fans stranded. In 2012, more than 400 Spanish supporters booked flights to Budapest, only to discover the Europa League match they’d traveled for was staged in Bucharest—about 400 miles away. A similar blunder unfolded in 2021 when French fans arrived in Bucharest expecting a game that was actually being played in Budapest. These embarrassing travel errors showcase how a simple confusion over city names can waste time, money, and patience.

8 Crypto.com Accidentally Refunded Someone Over $10 Million

Imagine requesting a $100 refund and receiving $10.5 million instead. That’s exactly what happened to a woman dealing with Crypto.com. After an audit revealed that an employee mistakenly entered the wrong account number, the platform processed a massive overpayment. The woman promptly purchased a $1.35 million house with the windfall. However, the exchange later sued, and Australia’s Supreme Court froze her assets, ordering her to sell the property and return the cash. This episode highlights how a tiny data entry error can unleash a financial avalanche.

9 US Forces Accidentally Built A Fort In Canada

Construction blunders aren’t limited to houses; they can even involve nations. In 1816, American engineers erected Fort Montgomery—later dubbed Fort Blunder—intended to guard Lake Champlain against British incursions. Due to a misreading of the border maps, the fort sat a mile inside Canadian territory. It wasn’t until the 1840s, after diplomatic negotiations refined the boundary, that the United States reclaimed the structure. The incident serves as a cautionary tale: even seasoned military planners can misplace a fort when they forget to double‑check the map.

10 Lou Reed Got All Royalties From A Tribe Called Quest’s Hit Can I Kick It

The Velvet Underground’s Lou Reed may have been a rock legend, but he also became an unexpected beneficiary of a costly sampling oversight. In 1990, A Tribe Called Quest released the classic “Can I Kick It,” which sampled Reed’s bass line from “Walk on the Wild Side” without securing clearance. The record label failed to clear the rights, and when Reed discovered the unauthorized use, he simply demanded payment. Consequently, the entire royalty stream from the hit flowed to Reed, leaving the hip‑hop group empty‑handed. This episode demonstrates how a missed licensing step can redirect millions of dollars to an unsuspecting artist.

10 Costly Mistakes Overview

From royalty disputes to fatal missteps on the soccer field, each of these ten stories shows that overlooking a single detail can have monumental, sometimes tragic, financial consequences. Keep an eye on the fine print—your next big mistake might just be waiting around the corner.

When you hear the phrase “10 simple costly,” you might picture a list of tiny blunders that somehow managed to cost fortunes, lives, or even entire missions. Believe it or not, the world’s most expensive disasters often trace back to a single misplaced decimal point or a misunderstood unit of measurement. Below we dive into ten jaw‑dropping examples where a math slip‑up turned into a headline‑making catastrophe.

Why 10 Simple Costly Errors Matter

From war‑time missile systems to high‑speed trains, each of these stories shows just how fragile our high‑tech world can be when the simplest arithmetic goes awry. Buckle up as we count down the most eye‑opening mishaps.

10 Gulf War Scud Missile Attack

On 25 February 1991 an Iraqi Scud missile slammed into a U.S. Army base at Dharan, Saudi Arabia, killing 28 soldiers and wounding 100 more. The base was supposedly shielded by a Patriot missile defense system, yet the system never even tried to intercept the incoming rocket.

The root cause was a timing glitch in the Patriot’s software. The clock logged time in deciseconds but stored it as an integer, later converting it to a 24‑bit floating‑point number. Rounding during each conversion introduced a tiny drift that grew larger the longer the system ran, eventually throwing the radar’s “look‑where‑the‑missile‑should‑be” calculation off by enough to miss the target after roughly 20 hours of continuous operation.

When the Scud struck, the battery had been awake for about 100 hours. The accumulated timing error meant the system was searching the wrong patch of sky, so the missile slipped by unnoticed. Although the Army knew of the issue and issued a software patch on 16 February, the update didn’t reach the Dharan unit until 26 February—one day after the tragedy.

9 Spain’s S‑80 Submarine Program

In 2003 Spain embarked on a $2.7 billion venture to build four diesel‑electric S‑80 submarines for its navy. By 2013 the first hull was nearly finished when engineers discovered it was a staggering 70 tons heavier than the design called for, raising fears that the vessel might never surface safely.

The excess weight traced back to a single misplaced decimal point in the weight calculations. The error went unnoticed until the lead submarine was completed, by which time the remaining three were already under construction, compounding the problem across the entire program.

Spain eventually struck a $14 million deal with Electric Boat in Groton, Connecticut, to trim the overweight hulls, but the miscalculation cost the nation time, money, and a serious credibility hit.

8 Air Canada Flight 143

In July 1983 a Boeing 767 operated by Air Canada took off from Ottawa bound for Edmonton with 69 souls aboard. Mid‑flight, the engines sputtered and the aircraft began a graceful glide from 12 500 m (41 000 ft) down to a former runway now serving as a racetrack in Gimli, Manitoba.

The drama unfolded because ground crews had filled the tanks using pounds rather than kilograms. The airplane’s onboard systems expected fuel in kilograms, yet the crew measured it in imperial pounds, effectively loading only about half the fuel needed for the journey.

Compounding the problem, the fuel gauge was out of order, and the crew relied on manual drip‑stick readings. The mistake was made twice—once in Montreal and again in Ottawa—so the plane completed the first leg without incident but ran out of juice on the Ottawa‑to‑Edmonton stretch, leading to the famous “Gimli Glider” emergency landing.

7 Sinking Of The Vasa

On 10 August 1628 Sweden launched the opulently armed warship Vasa, only to watch it capsize a mere 20 minutes after leaving the dock, taking 30 lives in the process. The wreck lay at the bottom of Stockholm’s harbor until salvaged centuries later and now resides in the Vasa Museum.

Modern historians determined that the shipbuilders inadvertently mixed two measurement systems: the Swedish foot (12 inches) and the Amsterdam foot (11 inches). This subtle mismatch made one side of the hull heavier, tilting the vessel and rendering it unstable.

When two sudden gusts of wind struck, the already top‑heavy design tipped the balance, and the Vasa quickly sank, illustrating how a seemingly trivial unit conversion can doom an entire fleet.

6 Mars Climate Orbiter Crash

The $125 million Mars Climate Orbiter, a joint effort between Lockheed Martin and NASA’s JPL, vanished in 1999 after a navigation error sent it careening into the Martian atmosphere. The probe was expected to enter a stable orbit, but instead it burned up on a fatal descent.

The culprit was a classic imperial‑metric mix‑up: Lockheed’s software produced thrust data in pound‑force seconds, while NASA’s ground control interpreted those numbers as newton‑seconds. The resulting trajectory miscalculation was small enough to slip past checks but large enough to cause the spacecraft to dip far below its intended orbit.

Engineers later described the incident as “dumb” and “embarrassing,” noting that a simple unit conversion oversight could have been caught with a bit more diligence, yet it cost a multi‑million‑dollar mission.

5 Ariane 5 Rocket Explosion

On 4 June 1996 the European Space Agency’s Ariane 5 rocket detonated just 37 seconds after lift‑off, taking four costly satellites with it. The total loss topped $370 million. The disaster stemmed from an integer overflow in the flight software.

Unlike today’s 64‑bit processors, Ariane 5’s guidance computer operated on 16‑bit integers, capping values at 32 767. The newer, faster rocket generated navigation data far exceeding that limit, causing the software to overflow and crash the control system.

Because the same software had performed flawlessly on the slower Ariane 4, engineers assumed it would scale, overlooking the fact that the new vehicle’s higher velocity produced larger numbers. The overflow forced a self‑destruct command, ending the mission in a spectacular blaze.

4 Bank Of America’s Dividend Payments And Stock Buybacks

In 2014, Bank of America announced it had passed the Federal Reserve’s stress‑test for the first time since the 2008 crisis, promising shareholders a fresh dividend and a $4 billion stock buyback. The celebration was short‑lived.

It turned out the bank’s analysts had mis‑valued a portfolio of Merrill Lynch‑owned bonds, inflating the institution’s health on paper. The error meant the stress‑test result was bogus, prompting a rapid retraction of the announcement.

The fallout was swift: the bank’s share price plunged by $9 billion—about 5 % of its market cap—on the very day the mistake was disclosed, underscoring how a simple arithmetic slip can shake investor confidence.

3 The Laufenberg Bridge Problem

Germany and Switzerland teamed up to span the Rhine between their twin towns of Laufenburg. The plan called for each nation to start building from its own bank and meet in the middle. By 2003 the bridge was nearly finished when engineers realized one half rose 54 cm (21 inches) higher than the other.

The discrepancy traced back to differing sea‑level references: Germany used the North Sea datum, while Switzerland relied on the Mediterranean datum. Although both nations knew about a 27 cm offset, a calculation error doubled the correction, leading to the noticeable height gap.

The mishap forced costly redesigns and highlighted how even agreed‑upon standards can go awry when the math isn’t double‑checked.

2 France’s Oversized Train Problem

In 2014 France’s state railway operator SNCF discovered that its brand‑new high‑speed trains were too wide for roughly 1 300 stations across the country. The trains, ordered from Alstom and Bombardier, exceeded platform clearances, jeopardizing passenger safety and incurring millions of euros in retro‑fit costs.

Investigations revealed that the railway authority, RFF, had omitted older, narrower stations from its measurements. While the newer stations were built to accommodate the larger train profile, the legacy stations weren’t, resulting in a nationwide compatibility nightmare.

The incident sparked public ridicule, with the transport minister dubbing it “comically tragic” and satirical cartoons urging commuters to “pull in their stomachs” as the oversized trains approached.

1 The Amsterdam City Council’s €188 Million Housing Benefits Error

In December 2013 the finance office of Amsterdam’s city council attempted to distribute €1.8 million in housing benefits to over 10 000 low‑income families. A software glitch, however, caused the system to treat amounts as cents rather than euros.

As a result, families received €15 500 instead of €155, and in one extreme case a household got €34 000 rather than €340. The mistake ballooned the total payout to €188 million, a staggering overshoot.

City officials managed to reclaim most of the funds, but €2.4 million remained unrecovered, with €1.2 million of that especially hard to retrieve. The city also spent €300 000 on legal and administrative efforts to resolve the fiasco.
