The scariest horror projects of all time

and its surprisingly happy ending

The lost luggage terminal

Heathrow Terminal 5

British Airways’ vision was clear: Heathrow Terminal 5 was to be the most modern terminal in Europe and ensure smooth handling. And indeed, after years of construction, the terminal opened on schedule in 2008. The project even almost landed on budget. But instead of rejoicing, there was still chaos. The baggage systems failed immediately, passengers had to wait for hours and over 30,000 suitcases disappeared into the void. It took months before the terminal was even halfway functional, as the baggage system was highly automated and very complex. The flagship project thus turned into a nightmare scenario, even live on television. However, British Airways quickly learned from the chaotic opening. Today, Terminal 5 is considered one of the most efficient airport terminals in Europe. The automation systems are stable, passenger feedback is positive and the initial glitches have become valuable lessons learned for the entire industry.

The mirror of horror

Hubble Space Telescope

The Hubble Space Telescope was to become the best telescope of all time and provide us with a completely new view of the universe. It was launched into space on April 24, 1990. Just a few weeks later, it delivered the first images from an orbit of around 540 km. But then came the shock, because the images were blurred. Murphy’s It turned out that the lens had been ground incorrectly by 2.2 micrometers. A tiny mistake with fatal consequences. The billion-euro project thus became a cosmic joke. Only a risky shuttle mission in 1993 was able to rectify the error and save Hubble, so that the telescope now transmits razor-sharp, spectacular images. After this repair, Hubble became a scientific sensation. It revolutionized our understanding of the universe, made countless discoveries possible and laid the foundation for the James Webb telescope.

The printer who saw ghosts

Xerox WorkCentre

But even projects that initially seem very safe can have fatal consequences. This is what happened with the Xerox WorkCentre. The innovative multifunctional device was designed to automatically process large volumes of documents and efficiently reduce the size of scanned images before printing by recognizing and replacing recurring patterns. In the early 2010s, Xerox WorkCentre made headlines with this technical miracle. Years later, the product turned out to be a bit of a nightmare, as the device “hallucinated” numbers in documents. Often a 6 or a 0 suddenly became an 8. The cause was the printer’s celebrated compression algorithm. It found visually similar patterns in the numbers, saved one of the symbols and replaced similar characters with this one in order to save memory and speed up processing. The big problem with this was that the faulty copies looked visually perfect and the error could go unnoticed for years. This was particularly dangerous with technical drawings or construction plans that suddenly showed incorrect dimensions, as well as with medical documents, in accounting or with legal contracts – in other words, in areas where an incorrect number could cost millions or even people’s lives. After the problem was discovered, Xerox released software updates that quickly corrected the compression. This allowed the device to remain in use.

The dance of the falling bridges

Hyatt Regency Walkway

There were much more tragic consequences at the Hyatt Regency Hotel in Kansas City. Opened in 1981, it was an elegant hotel with an eye-catching lobby and spectacular floating footbridges – a special design experience for visitors. But just one year after it opened, the unthinkable happened during a packed dance event: two of the floating bridges collapsed. 114 people lost their lives and over 200 were injured. The cause was a seemingly minor matter: a design change to the suspension of the bridges halved the load-bearing capacity without anyone checking it properly. The celebrated architectural achievement thus turned into a live disaster. Following this tragedy, construction and engineering guidelines in the USA were drastically tightened and civil engineers were given new inspection procedures so that project changes must now always be recalculated, documented and approved.

The cursed musical

Spider-Man: Turn Off the Dark

Many of the well-known horror projects have to do with buildings or developments, but this one involved a planned Broadway hit with superheroes, music by U2 and breathtaking stunts. However, it became clear during the realization that unrealistic expectations were being placed on the project and that too many decision-makers had their fingers in the pie. Rehearsals had to be stopped several times, artists were injured in risky flying scenes and the costs exploded to over 75 million dollars – a record for a Broadway show. After endless postponements, the musical finally celebrated its premiere, only to be torn apart by critics. Despite the disastrous reviews, the musical ultimately ran on Broadway for more than three years and grossed over 200 million dollars. A new record for the supposed fiasco. It was later used as a lesson in safety management, risk culture and creative control in the theater business.

The Phantom of the Opera

Sydney Opera House

The Sydney Opera House was to be an architectural masterpiece for eternity. It was to be completed within 7 years at a cost of 7 million dollars. But no sooner had it begun than problems began to pile up: technical challenges, political disputes, constant changes to the plans. The time and budget planning got completely out of hand. After 14 years of construction and over 100 million dollars, the architect resigned in resignation. It is said that he never set foot in Australia again. The opera house quickly became a national laughing stock before becoming a world-famous landmark decades later. The once national embarrassment is now synonymous with Sydney and Australia and has even been designated a UNESCO World Heritage Site. Its spectacular architecture has inspired generations of designers and architects and generates millions in tourism every year.

The mission to nowhere

Mars Climate Orbiter

The Mars Climate Obiter was a 327-million-dollar satellite designed to study the climate and atmosphere of Mars. From launch, everything went according to plan for weeks until the satellite swung into Mars orbit. The excitement was great until suddenly there was only radio silence. It turned out that the probe had burnt up before it could even enter orbit. The subsequent investigation showed that no technical defect was to blame, but a communication error between two teams. The development team responsible for the navigation software was calculating in imperial units, while the Nasa navigation team was calculating in metric units. Instead of flying at an altitude of 150 km, the satellite came within 57 km of the planet and burned up. The real tragedy: the error was measurable for months, but no one had openly questioned it.

The cursed masterpiece

Heaven’s Gate

But Hollywood is not spared from horror projects either. Heaven’s Gate was supposed to be an epic western by Oscar winner Michael Cimino and a triumph for United Artists. Unfortunately, the project fell victim to scope creep. Endless reshoots, excessive attention to detail and a director with no limits caused the budget to explode. Instead of 12 million, the film cost over 40 million, and filming took several months longer than planned. In the end, the film flopped at the box office. Heaven’s Gate ruined the studio United Artists and tore careers and finances into the abyss. However, the film is now considered a cult classic. Restored versions are shown at festivals and celebrated by critics as a misunderstood masterpiece. Its catastrophe led to structural changes in Hollywood: studios began to take budget control and production management seriously.

The giant with too short nerve cords

Airbus A380

The Airbus A380 was to be the largest passenger aircraft in the world. A prestige project that was to be technologically leading, luxurious and efficient at the same time. Airbus developed the A380 simultaneously at several European sites, for example in Toulouse, Hamburg and Broughton. However, this international collaboration brought with it difficulties in terms of digital integration, which initially went unnoticed. The different sites used different versions of the same CATIA CAD software. The result was electrical wiring harnesses that fitted perfectly in the digital models but were too short in the real aircraft because coordinates, bending radii and component positions were incorrectly synchronized. Delays of over two years and cost explosions of several billion euros were the result, as entire fuselage segments had to be rewired. The technical masterpiece initially failed due to organizational errors. The public scoffed, customers canceled orders and the project threatened to collapse. However, after restructuring and introducing standardized systems, Airbus was finally able to deliver the A380. Subsequent projects, such as the development of the successor A350, benefited massively from the now standardized design systems and went much more smoothly.

Conclusion

These horror projects have one thing in common: they started with good intentions and ambitious goals, but ended up in a mess of bad decisions, budget overruns, poor planning or a lack of communication.
