You’ve probably seen the Spielberg movie. Or maybe you've heard people joke about being "beamed up." But most folks get the terminology totally mixed up. When we talk about close encounters of the second kind, we aren't talking about seeing lights in the sky or chatting with a grey alien in a cornfield.
It’s about the leftovers.
In the world of ufology—a field that sits somewhere between fringe science and cultural obsession—a "second kind" encounter is all about the physical impact. It's the scorched grass. It's the car engine that mysteriously dies. It's the weird metallic taste in a witness's mouth that won't go away for three days. Basically, it’s when a UFO leaves a receipt. Dr. J. Allen Hynek, the astronomer who worked on Project Blue Book, came up with this classification system because he realized that eyewitness testimony is notoriously flaky. Humans lie. We misinterpret things. We see Venus and swear it’s a mothership. But a hole melted in a cedar tree? That's harder to dismiss.
What Actually Counts as a Second Kind Encounter?
Hynek was a skeptic at first. He really was. The Air Force hired him to debunk this stuff, but the physical evidence eventually made him change his tune. He defined close encounters of the second kind (CE-II) as events where an Unidentified Aerial Phenomenon (UAP) leaves a tangible effect on the environment or on biological organisms.
This isn't just "I saw a disc." It's "I saw a disc and now my radio is fried."
The effects usually fall into a few weird categories. You’ve got interference, which is the classic horror movie trope where the car headlights flicker and die as something passes overhead. Then there’s environmental marking, like the famous "crop circles" (the real ones, not the ones made by guys with planks of wood) or dehydrated soil. Finally, there’s the biological impact. This is the scary part. We’re talking about radiation burns, temporary paralysis, or even nausea.
It’s messy. It’s physical. And honestly, it’s the only reason the scientific community even looks at this topic without immediately laughing.
The Case of the Falcon Lake Burn
If you want to understand the reality of close encounters of the second kind, you have to look at Stephen Michalak. In 1967, Michalak was prospecting for silver near Falcon Lake, Manitoba. He wasn't some conspiracy theorist; he was an industrial mechanic. He saw two glowing objects. One landed.
When he got close, he heard voices. He thought it was a secret US military craft. He called out in several languages, but no one answered. When the craft took off, a blast of hot air or gas hit him through a vent.
It didn't just scare him. It burned him.
He ended up in the hospital with a grid-like pattern of burns on his chest—literally the shape of the vent he described. For weeks, he suffered from diarrhea, headaches, and a massive drop in his lymphocyte count. This is a hallmark of CE-II. The evidence wasn't just a story; it was etched into his skin. The RCMP and the Royal Canadian Air Force investigated. They found a circle of scorched earth where the craft had landed. No one could explain why the soil was radioactive.
Why Does Technology Go Haywire?
One of the most common reports in close encounters of the second kind involves electromagnetic interference (EMI). You're driving down a lonely road in New Mexico or the Scottish Highlands, and suddenly, the music stops. The engine stalls.
Why?
Physicists who dabble in this stuff, like Dr. Harold Puthoff, suggest that whatever propulsion system these objects use might involve massive amounts of microwave energy or intense magnetic fields. If you move a high-energy field past a car's ignition system, you get "Lenz's Law" in action. Current is induced where it shouldn't be. Circuits overload.
Interestingly, these effects are almost always temporary. Once the object leaves, the car usually starts right back up. It’s like the environment is being briefly "hijacked" by a localized physics anomaly.
The Mystery of "Angel Hair" and Physical Residue
Sometimes the evidence isn't a burn or a dead battery. Sometimes it's a substance. Throughout the 1950s and 70s, there were dozens of reports of a fibrous, cobweb-like substance falling from the sky after a UFO sighting. People called it "Angel Hair."
In 1954, in Florence, Italy, thousands of people—including soccer fans at a stadium—saw two cigar-shaped objects. Afterward, this white, snowy fluff fell over the city. A few brave souls actually took samples to the University of Florence. Analysis by Professor Giovanni Canneri showed the material contained boron, silicon, calcium, and magnesium. It was non-radioactive, but it sublimated—meaning it turned from a solid to a gas—almost instantly.

We don't see as much of this today. Maybe the "tech" changed? Or maybe we’re just less observant. But these residues represent the "holy grail" for researchers because they provide a chemical signature that doesn't match standard aeronautical debris.
Misconceptions: It’s Not Always Aliens
Let's be real for a second. Just because a car dies or a circle is burned in the grass doesn't mean "little green men" were there. Part of the complexity of close encounters of the second kind is ruling out the mundane.
Ball lightning can cause electromagnetic interference. It can burn things. Plasma phenomena, which we’re still learning about, can mimic many of the traits of a CE-II. Then you have the military. High-frequency directed energy weapons are a real thing. If a civilian wanders too close to a classified test of a microwave-based crowd control system or a new drone propulsion unit, they might experience "UFO symptoms."
- Geological Stress: Some researchers, like Michael Persinger, argued that tectonic strain in the Earth's crust could create luminous orbs and electromagnetic fields that cause hallucinations or physical sickness.
- Pranks: Let's face it, people love a good hoax. Chemical fertilizers can kill grass in a perfect circle if you're dedicated enough.
- Mass Hysteria: While it doesn't explain physical burns, it can explain why a whole town thinks their radios are acting up.
The Scars on the Land
Physical traces in the soil are perhaps the most analyzed aspect of this whole thing. When a craft—whatever it is—lands, it compresses the earth. But it’s the chemical changes that keep soil scientists up at night.
In many CE-II cases, the soil becomes "hydrophobic." You can pour water on it, and it just beads up and rolls off, like you’re pouring it on a rain jacket. This suggests the soil has been subjected to intense heat or a specific type of radiation that coats the grains in a waxy substance. You’ll also find that plants in the "landing zone" grow weirdly. Sometimes they die instantly. Other times, their cellular structure is altered so that they grow at three times the normal rate.
Jacques Vallée, a computer scientist and perhaps the most respected living UFO researcher, has spent decades collecting these soil samples. He argues that the "evidence" is often a form of "meta-materials"—isotopes that don't occur naturally on Earth in those specific ratios.
What to Do If You Encounter a CE-II
If you ever find yourself in a situation where you think you're witnessing a close encounter of the second kind, your "explorer" brain might kick in. But your "survival" brain needs to be faster.
- Keep Your Distance. If an object is close enough to affect your car or the ground, it's likely emitting some form of energy. Radiation burns aren't a joke. Don't run toward the light.
- Document the Environment. Use your phone, but don't just take a video of the sky. Record the dashboard of your car. Is the clock spinning? Is the GPS lost? Record the sounds. Often, these events are accompanied by a "hum" or a "beeping."
- Don't Touch the "Trace." If you see a scorched patch or weird "angel hair," do not touch it with your bare hands. Use a clean glass jar or a plastic bag if you must collect a sample, but honestly, call a professional.
- Check Your Electronics. After the event, see if your phone's battery drained unusually fast. Check your watch. Time dilation is a reported side effect, though that pushes into more theoretical territory.
- Seek Medical Attention. If you feel nauseous, have a "sunburn" you can't explain, or feel a metallic taste in your mouth, get a blood test. Specifically, ask about your white blood cell count.
The reality of close encounters of the second kind is that they take the phenomenon out of the realm of "stories" and into the realm of "stuff." It’s the difference between hearing a ghost story and finding a footprint in the flour on your kitchen floor. Whether these things are extra-terrestrial, military, or some weird atmospheric fluke, they leave a mark. And as long as they leave a mark, we have something to study.

Investigating these cases requires a mix of skepticism and open-mindedness. You have to look for the prosaic explanation first. Was there a power line leak? A localized lightning strike? But when those options are exhausted and you're left with a radioactive hole in the ground and a witness with radiation sickness, you have to admit that something very strange is happening in our skies.
To stay informed or contribute to the data, you should look into the databases maintained by the Mutual UFO Network (MUFON) or the Scientific Coalition for UAP Studies (SCU). They prioritize these "physical trace" cases because they are the only ones that can be measured with a ruler and a Geiger counter. If you have physical evidence, that is where the real science begins.
