It's summer in 1996, and a Boeing 747 explodes in view of New York City. What was once a symbol of the aviation world reaching its pinnacle becomes a symbol of the diverging gap between engineering and the general public.

As of 2026, it's become increasingly obvious how science has lost the general population's belief in the United States. It seems harder than ever these days to come up with concrete and clear explanations for things online. Not only does misinformation lurk, but hallucinations and conspiracy theories continue to impede clear consensus.

The paradigm has shifted inwards: science and technology are being shaped more than ever by political culture, and not vice versa. Science does not inform the agenda, the agenda informs the science and what is reported from it.

Often, I wonder about how this happened. Our institutions of academia, pharmaceuticals, and research were supposed to lift the burden of expertise from the general public. We rely on other people for abstractions of everything — abstractions of labor (like going to the grocery store instead of harvesting our own food), knowledge, and safety.

We agreed long ago that as opposed to living independent lives in solitude, it was better to live in clusters and specialize aspects of life to the people who were best at it.

Why in this modern world where we are the most "advanced" we've ever been, do we fail more than ever to trust that specialization and abstraction layer designed to make our lives easier? The answer can be found in so many tendrils of history, but I want to dissect it from an unexpected place: the vividly gruesome, unlikely, and confronting story of TWA Flight 800.


TWA 800 was a flight leaving New York to Paris in the summer of 1996. In a beautiful Boeing 747 nearing the end of its service life, 230 people waited on the ground for a delay of 80-ish minutes with the air conditioner running. Because Paris was relatively close for a 747's capacity, the wings were full of fuel but the center fuel tank wasn't refueled.

Instead, a small amount of unusable fuel sloshed around.

An issue with the fueling system started on the ground, and was a minor part of the delay. The automatic fueling cut-off system triggered too early, and was manually overridden by a worker on the ground. This system is designed to prevent overflow of the fuel tank, but erroneously reported the tank was already full.

The plane took off around 8pm, and the captain remarked that the fuel indicator was "going haywire." They continued to thrust the plane into the sky. TWA Flight 800 exploded as it climbed to 15,000 ft.


There are some aviation accidents where the plane is automatically disintegrated and everyone perishes brutally, yet in swift peace.

Not TWA Flight 800. The 747 broke up into two pieces.

The nose separated completely from the body of the airplane and dropped like a stone into the water below. The rest of the passengers suffered a decidedly worse fate. The body with wings attached, sans nose, continued to climb with its passengers open to the sky, reaching a pitch and then stalling. It tipped back down and met the fate of the cockpit that awaited it in the water. On the arc down, the wings exploded and disintegrated.

The remnants pirouetted into the water, which by proxy became inflamed.

The boats in the surrounding area flocked towards the plane that fell out of the sky above them. When they arrived, they found less than nothing. The water and fuselage was on fire from all of the fuel held in the wings.

Everyone was dead.


Those who witnessed it were aghast. What in the absolute fuck could cause a nose to detach from a plane body in mid-air? Not just any plane, but a 747 flying out of New York to Paris, in view of some of the most populated areas of the East Coast. The accident's visibility gained it an immense amount of conspiracy, public specter, and fear.

It's important to mention at this point that New York was on edge. In 1993, the World Trade Center experienced a bombing that killed 6 and injured a thousand. The American people didn't yet meet the levels of fear created by 9/11, but there was an elevated amount of concern about terrorism. Airplane hijackings were not uncommon. To see a plane break apart does not leave room for rationality in the forefront of the minds of the public. To them, the cause was already clear and the implications already set in motion.

Needless to say, news about the crash was everywhere and intensely scrutinized. The National Transportation Safety Board (NTSB) had their work cut out for them in many ways. During the investigation, they dispatched one of the largest teams and wrote one of the most intensive reports in their history. But, the FBI hit the ground running as well.

The FBI had already interviewed many of the eyewitnesses prior to the NTSB, providing at least a minor amount of credulity to the possibility of terrorism. Meanwhile, the NTSB got to work pulling up debris from the ocean and recreating the plane fuselage as best they could.

While they found over 192 possible holes that could have indicated a penetration of a missile, it was determined with forensic engineering that this was coming from destruction starting from inside the plane. Where it looked like there was missing metal, it was often rolled and folded into the edges of the damaged area.

There were some explosive materials found on some parts of debris, but none of it was concentrated from one area and it didn't look like material that went through an explosion. Most damning, it was determined the ocean water would have washed away the residue, and so the explosive material must have been placed after the fact. The current leading theory on this is that investigators (some who worked with explosives) may have accidentally contaminated it after.

The sound of the explosion from the cockpit tapes was completely different from those of other recorders of planes downed by bombs. None of the bodies inside were damaged by shrapnel like victims of other plane bombings or missile shutdowns, but they died by blunt force trauma. This is particularly significant — the shrapnel of bombs and missiles can be driven deep inside of the body, and used to determine what kind of missile or bomb exploded.

Therefore, TWA Flight 800 had none of the tell-tale signs of a bomb. Just eyewitnesses and the fear that terrorism would strike America again.


In some ways, the cultural climate prior to the accident had already determined in people's minds what the true cause was. Terrorism usually accompanies a "claimant" of terror. On the other side, the United States government was looking for any reason to escalate its wars in the Middle East, and were watching things escalate prior to September 11th for many years. I truly believe that if there was a bombing, there's not the incentive for either party to hide it. In fact, it would probably be more beneficial to the government's and the theoretical terrorists' agenda to claim responsibility.

Terrorism means financing on both sides. Tragedy is a political ploy, and it doesn't make sense to me to cover up something that certainly would have garnered support from the U.S. public, as well as an easier wave of funding. If I speculate, I wonder if the public's reaction and fear to Flight TWA 800 pushed the Taliban to utilize planes in future terrorist attacks. Our fear may have created a self-fulfilling prophecy.

Some people claim that the flight was taken down by an accidental US military exercise (some say from a submarine, some say from the ground, the coconuts say aliens). To which, I bring up the point again of the bodies not having shrapnel embedded within them.

This will never be an argument that science can fight, because it's an argument about trust. Why should we trust the NTSB to tell the truth? Most bluntly, would our government be honest with us if they did make a mistake? From what we know, the U.S. has only shot down a single civilian airliner, Iran Air Flight 655 in 1988. The US denied responsibility for it, yet paid millions in settlements.

An accidental shutdown is a farfetched idea that I wouldn't take seriously in 1996. Perhaps, it's one I would consider in 2026. However, someone being likely to do something does not necessarily mean that thing happened. It wouldn't be out of their element, but something being probable is not the same as it being the truth.

Aviation accident investigations are about many things, but primarily are a form of progress obtained through truth. An aviation accident is a devastating thing to be involved in, or around in any format. The best we can extract from it is applying the principles of engineering and forensic investigation as a means of justice. We need to know where things went wrong to heal them. We need to know, for our engineering safety and for our human anxieties, what the truth is.

The NTSB went to extreme lengths and experiments to find the truth. I don't trust the government, but I trust the individuals running the NTSB, and I trust the methodology they use.

But, if a bomb or missile didn't take down TWA Flight 800, what did?


The most probable answer is more baffling and terrifying.

The NTSB dug more into how the plane disintegrated, and the specific detail that the nose separated from the rest of the plane. The nose section was devoid of evidence of fire, whereas the main body was shown to have significant fire damage.

When the NTSB modeled how the plane broke apart from the structural damage found, and its location along the remnant path, they found the first area to go was a structural span-wise beam that was directly in front of the center-wise fuel tank. The baggage claim, where the bomb theoretically could have been, was untouched.

The first part of the plane to go was the underbelly, then the structural elements holding the nose to the rest of the fuselage. The nose detached, and the rest of the plane continued forth without it. This led to one of the most controversial conclusions in aviation investigation history.

The center fuel tank sparked and exploded, and this led to the plane somewhat cracking in two, as the pressure pushed outwards causing the bottom fuselage to collapse. It was not an explosion as much as it was a cracking of the structure.

The culprit was right under everyone's feet. If you've ever flown, it has been under your feet as well. A fuel tank exploding was quite a fucking far out guess for the time. Jet fuel was supposed to be very hard to ignite, if not impossible. But, planes are supposed to be quite hard to snap in two in the sky.


Conditions for liquid jet fuel to be ignitable are supposed to be hard to create. The idea is that if the flash point (when fuel would become highly flammable) is higher than what the fuel tank would ever experience, the fuel within the tank would remain inert. But, this assumption was based on a limited literature study from the 1970s that hadn't been thoroughly tested or reviewed since.

The circumstances on TWA 800 theoretically lowered the flash point of the fuel, making it more likely to ignite. Flash point is not a set temperature, but a combination of temperature and pressure. The fuel pumped into the plane from the supplier had a flash point of 114 degrees on the ground, but 96 degrees at an altitude of 15,000 ft. Fuel is hard to ignite when it's liquid, but beyond the flash point, it's a vapor and mixes with the air. The fuel fills the entirety of the tank: any spark anywhere in the tank can ignite.

Starting at the beginning of Flight 800, the low amount of fuel meant it was relatively easy to heat up, lowering the flash point. The air conditioning running for 2 hours vented hot air directly at the fuel tank, and the pressure rising from the altitude made it flammable, creating a vapor in the tank waiting for a spark.

How would the spark possibly happen? There are regulations that force manufacturers and anyone working on the plane to assume a fuel tank is ALWAYS flammable. Regardless of the intentions around design constraints, there have been at least 15 incidents in aviation history where the fuel tank exploded. Most of these have been because of a lightning strike, and didn't start from within the fuel tank itself.

The most eerie of all was Philippines Air Flight 143. A brand new 737 exploded on the ground and killed 8 people when the center fuel tank ignited because of an arc from the sensor that measures how much fuel is in the tank.

The noise of the cockpit recordings of TWA Flight 800 and Philippines Air Flight 143 were as similar as they could be. Not the sound of a sharp pinnacle, but of a rumble from below that took both planes into their fate.

Although the fuel depth sensor wiring is not supposed to have enough electricity to start a spark, wires are often bundled into "racetracks." These are locations within the fuselage where wires for numerous electrical systems are bundled together to be routed through a plane. The 747 has over 150 miles of wires within it.

Wiring can corrode over time and cause wires to become more charged with electricity than intended. Even if a sensor is not supposed to have enough energy to spark, it can rub up against other wires that transfer higher amounts of electricity, if the wiring is not in good condition.

TWA got the 747 new in the 1970s, and it was near the end of its service life at the time of the accident in 1996. The general condition of the wires was bad — there was metal shavings, breaks in insulation, evidence of unknown fluids everywhere (fluids on wiring can induce a short circuit), and other repairs to the electrical system were poorly done or not recorded at all.

The sensor wires that they could find had stripped insulation, showing many places where the wires could have crossed.

The fuel sensor was not supposed to have enough energy to ignite the fuel mixture — but ultimately, it seems it did. Many signs point to faulty wiring in retrospect: the problems with the fueling that the ground crew manually overrode, the fuel gauge indicator "going crazy," and electrical interference posthumously captured in the cockpit recorder. Outside of the accident, the plane itself had electrical issues within the cockpit radio, cabin lighting, and in-flight data recorder.

The NTSB never found the exact wires responsible, but they did find evidence of arcing between wires in the raceways in other sections of the fuselage. The fuel tank indicator when recovered also showed twice the amount of fuel that was actually loaded onto the plane, despite the correct amount showing and being reported on takeoff.

Although it will never be confirmed exactly, the circumstances were recreated by experiments the NTSB and other experts ran over 2 years. To their complete shock, they were able to replicate an explosion.


The fuel tank system wiring was intertwined with higher-voltage wiring, which possibly allowed more energy to come into the fuel tank than was designed through the fuel tank depth sensor. There was either a short circuit or an arc, with clear signs pointing to the electrical systems not operating correctly up to and during the accident.

The fuel in the center fuel tank had a lower flash point due to the low quantity, and proximity to the air conditioning packs placed below. Perhaps, it was just a matter of time until the flash point lowered, the electrical error sparked, consuming the plentiful oxygen in the tank. The fuel vapors ignited and disintegrated the structure connecting the nose and the rest of the plane body.

The underbelly of the fuselage was the first to go, peeling the underside away first and likely exposing the fire to the sky. Then, the structural beams broke apart, and cracked the plane like a Pocky stick. If you've ever pushed downwards on a brittle stick or box to watch the ends push up as the bottom fell out, you know the forces exerted on the 747.

The fireball in the sky people saw was not a missile arcing towards the plane that cracked it, but the plane itself. Catching fire, splitting, and then falling from the split.

All from a single, alleged electrical event. One that can never be confirmed, because the wires are lost to the world forever.

But, an unlikely electrical event that took the lives of 230 people. Not through terrorism, but something arguably worse: misfortune.


This is, of course, a very unsettling and terrifying conclusion. Jet fuel is not supposed to be easily flammable. And not to mention, if this plane exploded from the fuel tank, what other plane was imminently about to self-destruct? The sequence of events was not only highly improbable — it could have happened to anyone. Could still happen to anyone back when the investigation concluded, prior to the industry implementing inert fuel systems.

It was not an aviation accident where a direct human factor was at play. No one knew the true danger that lurked, nor could it theoretically have been foreseen prior to. The electrical event of the fuel tank probe met a cultural climate of fear, and didn't provide an easing answer. In fact, it seemed so improbable that to the public, it must have still been a cover-up.

This is not limited to TWA 800 in any scope, and remnants of this conspiracy thinking against expert opinion shows up again and again. Most related to this is the collapse of the Twin Towers during 9/11. That's not to say that there's not terrible accidents that happen and are covered up.

JAL 123 crashed into a mountain, and the botched government rescue left 20–30 survivors to die. Air India Flight 171 is being painted by the Indian government as a niche engineering failure as opposed to a deliberate effort by the Captain to engage in a brutal murder/suicide. There are many such cases of bombings, terrorism, government incompetence, and more involving transportation accidents all over the globe. But, Flight TWA 800 seems like it was not the case.

In many ways, the truth about what is safe and what is not is harder and harder to face, and to explain to the general population. We have some of the safest transportation systems ever known, and yet the failures are rare and vicious — oftentimes more prone to spectacle and conspiracy.

Sometimes, engineering can fail us, and the science behind the failure is not a compelling solution to the fear we experience every day within our world. If one of the most iconic jets in history can explode without warning over a major population center, what could happen to us?

Conspiracies are helpful because they bring the unknown into the realm of control. It is not a mishap of science, it is a direct offense. It is a failing government, it is a terrifying entity that lurks. The thing to fear is not the statistics of who will live and die that trace through all parts of our shared landscape, but something that is easy to get angry at, and that we can solve.

Faulty wires and low fuel. A pilot switching off a fuel valve. An intense fire in a skyscraper.

This is how brittle our world can be. Conspiracy is a salve to the pain of living within that brittle world.


There are often so many layers of abstraction to everything in our lives, from manufacturing, to engineering and more. This abstraction provides a tranquilizer-like effect to the luxuries we experience every day. But, that abstraction comes at a high cost, especially when something incredibly critical seems to fail.

Sometimes, we just don't know. The experts you trust put you on a plane that crumples beneath your feet. They may deliver vaccines that cause a very small percentage of the population to have adverse effects. We at scale are experiencing the pains of human science.

Aviation is a microcosm of these things, because it's where they're most at tension. It's a miracle of science to have aviation even exist, an entire industry based off of the premise of geometry and physics. By designing a simple airfoil, we have created a new form of terror that not even the most experienced of us can know the full extent of.

That level between science, what it can discover in time, and what it looks like for the public will forever be a race against time and tension. I do not blame the general public for not believing in TWA Flight 800, because even as an aviation enthusiast — it is a hard pill to swallow. And it is one we swallow over and over again as we continue to advance technology at scale forward, in the constraints of a world that does not see the investment of safety as paramount.

Although the wire spark to fuel tank explosion theory is a guess, it led directly to lives saved. On planes today, an inerting system pumps nitrogen into fuel tanks to prevent ignition from taking place. By removing oxygen, there cannot be a fire started within the fuel tank. This is a system that has been in function for you if you've been on modern planes, and no doubt a system that has saved lives.

Accepting the limits of science is accepting the limits of our control. Accepting that our culture will always filter through to our conclusions is another. Science is a fight for the truth, against the fight of what feels right to the greater populace in the current cultural moment. Truth is not comfort, and truth often lacks consensus.

Perhaps, this is where science fails and needs another framework. Having knowledge of failure is not the same as having remediation for comfort. We will win the fight for truth, but we will not win the fight for comfort. The all-seeing eyes of science and engineering are still just human, bound to the laws of failure like all of us. There may never be a framework we can employ in our modern world that escapes that.
