Engineering is usually about safety. We build bridges so they don’t collapse, planes so they don't fall, and roller coasters so they provide the thrill of death without actually, you know, delivering it. But in 2010, Julijonas Urbonas decided to flip that script entirely. He designed the roller coaster that kills you. It isn't a "creepy pasta" or a legend from the dark web; it’s a conceptual project called the Euthanasia Coaster.
It’s a machine designed to take a human life with "elegance and euphoria." That sounds incredibly dark because it is. Urbonas, a PhD candidate at the Royal College of Art in London at the time, wasn’t actually trying to build a theme park attraction for executioners. He was a former employee of a Lithuanian amusement park. He knew exactly how G-forces mess with the human body. He wanted to merge the world of high-tech engineering with the philosophy of death, creating a hypothetical way for a person to go out on a literal high note.
The Brutal Science of G-Force
How does a roller coaster actually kill someone? It’s not through a crash or a mechanical failure. In this design, it’s all about cerebral hypoxia. Basically, your brain runs out of oxygen.
The ride starts with a massive, soul-crushing climb. We’re talking about a 510-meter drop. For context, that’s over 1,600 feet. That is taller than the Willis Tower in Chicago. You sit at the top, looking down, and you have a choice. You can press a button to start the descent, or you can stay there. It’s designed to give the rider a final moment of reflection.
Once you drop, you hit speeds of 100 meters per second. That's fast. 223 miles per hour fast.
Then come the loops. Seven of them.
Why Seven Loops?
The loops are engineered to maintain a constant $10g$ force for 60 seconds. In a normal coaster, you might feel $4g$ or $5g$ for a split second. Fighter pilots deal with $9g$, but they wear specialized G-suits that squeeze their legs to keep blood in their brains. They are also trained to perform the "AGSM" (Anti-G Straining Maneuver). The rider on the roller coaster that kills you has none of that.
As you enter the first loop, the blood in your body rushes to your feet. Your heart isn't strong enough to pump against that kind of force. First, your vision goes. It’s called "greyout," then "blackout." Then comes "GLOC"—G-force induced Loss Of Consciousness.
By the third or fourth loop, it’s over. The remaining loops are just there to ensure the job is done. Biologically, the brain is exceptionally sensitive to oxygen deprivation. Prolonged exposure to $10g$ ensures that even the most resilient person wouldn't survive the minute-long ordeal.
The Ethical Quagmire
Critics haven't been quiet about this. Dr. Desmond O'Neill, an expert from the Irish Society of Medicine, famously spoke out against the concept. He argued that the "death coaster" was a grotesque simplification of end-of-life care. He wasn't wrong. Euthanasia is a deeply personal, medical, and legal minefield. Urbonas, however, argues that his design provides a "ritual."
In a modern medical setting, death is often sterile. It’s hospital beeps and white walls. This coaster proposes a death that is active, visceral, and, in a strange way, celebratory of the human experience of physics. It’s a bit "over the top," sure. But it forces us to ask: If we have the right to die, do we have the right to choose the manner of that death?
Is It Even Possible to Build?
Technically? Yes. We have the materials. We have the math. The structural integrity required for a 1,600-foot lift hill exists—just look at the Burj Khalifa.
But practically? No way. No insurance company would touch it. No government would approve the zoning. And let’s be real, the cost of building a 500-meter steel structure just for a single-use "service" is a financial nightmare. It’s a thought experiment, a piece of "speculative design." It’s meant to provoke, not to be featured on a park map next to the cotton candy stand.
Human Limits and the "Thrill"
People often ask why we are so fascinated by a roller coaster that kills you. It's because we are obsessed with the edge.
Think about the "Smiler" at Alton Towers or the "Kingda Ka" at Six Flags. We pay money to feel like we are dying. We want the adrenaline, the stomach-drop, and the fear. The Euthanasia Coaster just removes the safety net. It’s the logical, albeit horrific, conclusion of the "bigger, faster, scarier" arms race in the amusement park industry.
Interestingly, Urbonas mentioned that the idea was partly inspired by the "death" of the coaster industry itself—how rides have to keep getting more extreme to satisfy a jaded public.
- The ride duration: roughly 2 minutes of ascent, 1 minute of descent/loops.
- The physical toll: complete oxygen starvation to the brain.
- The result: 100% fatality rate by design.
Honestly, it’s a bit of a miracle that our bodies can handle any G-forces at all. Most people don't realize that a simple sneeze can put more momentary G-force on your body than a gentle carousel ride. But the sustained pressure of $10g$ is a whole different beast. It literally flattens your internal organs and prevents your lungs from expanding.
Why It Matters Today
We live in an era where "assisted dying" is becoming legal in more jurisdictions—places like Canada, Belgium, and several US states. As these laws evolve, the conversation about how people leave this world becomes less about science fiction and more about actual policy.
The Euthanasia Coaster serves as a dark mirror. It asks if we want death to be a medical procedure or a final performance. Most people find the idea of a "death ride" repulsive, which actually tells us a lot about our current cultural values regarding dignity and the end of life.

Actionable Insights for the Curious
If you're fascinated by the physics of high-intensity rides but would prefer to stay alive, there are ways to engage with this safely:
- Study High-G Physiology: Look into NASA’s research on human G-tolerance. It’s fascinating to see how the "human centrifuge" is used to train astronauts.
- Visit Real Record-Breakers: If you want the closest safe experience to extreme heights, visit Zumanjaro: Drop of Doom at Six Flags Great Adventure. It’s not 500 meters, but it’s enough to make your heart jump.
- Explore Speculative Design: Check out other works by Julijonas Urbonas. He explores how the body reacts to extreme environments in ways that aren't always about death, but always about the "limits" of being human.
- Understand Euthanasia Laws: If the ethical side interests you, research the "Oregon Death with Dignity Act" to see how real-world assisted dying is actually handled. It is much more mundane—and much more complex—than a roller coaster.
The roller coaster that kills you will likely never be more than a scale model in a museum or a 3D render on a screen. And honestly? That's probably for the best. Some things are better left as ideas, reminding us of the thin line between a thrilling ride and a final one.
