It was a bright June day in 1947. Pilot Kenneth Arnold was flying toward Mount Rainier in Washington State. He was looking for a plane that might have crashed there. 

Arnold never found the plane. But he did find something else. 

What he saw was unbelievable. It would change his life—and American history—forever.

It was something that he later believed was not from Earth.

That’s right. We’re talking about aliens.

It was a bright June day in 1947, and pilot Kenneth Arnold was flying over beautiful snow-capped mountains. He was on his way to Oregon, but he had decided to head off course to Mount Rainier in Washington State. A military plane was thought to have crashed there. A reward was being offered to the first person who found it.

Arnold never did find the downed plane. But he did find something else.

Something so extraordinary that it would forever change the course of his life—and American history.

Something he would come to believe was not of this Earth. That’s right. We’re talking about aliens.

Alien Fun

After Arnold spotted flying objects in 1947, there was a burst of similar reports. Many were in the Southwest. Today, people visit that part of the U.S. to enjoy restaurants, museums, and gift shops based on UFOs and aliens. There’s even an alien festival!

The Mystery Begins

The Mystery Begins

The Mystery Begins


Arnold saw nine strange objects in the sky. At first he thought they were birds. But that couldn’t be. The objects were shiny. Sunlight flashed off them. Sometimes they darted and flipped. Were they planes? Unlikely. The objects didn’t seem to have pilots. 

Even crazier, they were traveling at least 1,200 miles per hour. At that speed, you could cross five football fields in about one second! Arnold didn’t know anything that flew that fast. 

He was puzzled—what were they? If only he had a camera with him.

After he landed, Arnold told his story to other pilots and a reporter. A newspaper ran an article about what he’d seen. According to the article, the flying objects were “saucer-like.” (A saucer is a small, round plate.)

The story was quickly shared by other newspapers. It started a frenzy. What had Arnold seen? Had he seen spaceships flown by aliens?

Americans became obsessed with the story. Within a month, people across the country reported seeing more than 850 unidentified flying objects (also known as UFOs).

Americans became obsessed with the story. Within a month, people across the country reported seeing more than 850 unidentified flying objects (also known as UFOs).

Arnold saw nine strange objects in the sky. They were shiny. Sometimes, they flipped around while moving. And they moved faster than anything he had ever seen. But Arnold didn’t see any pilots flying the objects. 

Arnold told people about the strange objects. Newspapers wrote articles about them. The objects were described as “saucer-like.” A saucer is a small, round plate.

Arnold’s story started a frenzy. People wondered if Arnold had seen alien spaceships. People across the country started seeing UFOs. (UFO stands for unidentified flying object.) Farmers saw strange lights. Kids saw flying saucers in the sky.

People formed clubs to discuss UFO reports. Some of the most popular movies and TV shows had aliens in them. The mystery remained: Were people really seeing alien spaceships?

The Mystery

As he got close to Mount Rainier, Arnold saw nine strange objects in the sky. At first, he thought they might be a flock of birds. But thatcouldn’t be. The objects had shiny surfaces, and sunlight sparkled off them. Were they planes? Unlikely. The objects didn’t seem to have pilots, though they sometimes darted and flipped.

Even crazier, the objects were traveling at 1,200 miles per hour or more, according to Arnold. At that speed, you could cross fivefootball fields in about one second! Nothing flew that fast, Arnold knew—and certainly not birds. He was puzzled. If only he had a camera with him, he thought.

After he landed, Arnold told his story to other pilots and a reporter. On June 25, the East Oregonian newspaper ran a front-page article about Arnold’s story. According to the article, the flying objects Arnold saw were “saucer-like.” (Saucers are small, round plates.)

“It seemed impossible,” Arnold said in the article. “But there it is—I must believe my eyes.”

The story was quickly picked up by other newspapers. And it sparked a frenzy. What had Arnold seen? Could it have been some kind of military test? A weapon? Or was it something stranger? Was it aliens?

Whatever it was, the public became obsessed. Within a month, people reported seeing more than 850 unidentified flying objects—or UFOs.

UFO Hunting

UFO Hunting



Over the next few months, people continued seeing UFOs. Farmers saw strange lights over their fields. Kids spotted flying saucers high in the sky.

In July 1947, a mysterious object was found in the desert near Roswell, New Mexico. Rumors spread that aliens had crash-landed there. (An official report said that a weather balloon—not a spaceship—had crashed near Roswell.)

UFO hunting became a hobby. People formed clubs to discuss UFO reports. Some of the most popular movies and TV shows featured aliens. Sometimes these aliens were friendly. Sometimes they were terrifying.

Meanwhile, the mystery remained: What were people seeing? Could these UFOs really be alien spaceships?

What’s Out There?

For as long as humans have walked on Earth, we have gazed up at the sky and wondered what might be out there. And we’ve told stories to try to explain what we don’t yet understand.

Early humans saw the shapes of great and powerful beings in the night sky. Now we know those shapes are stars and planets.

In the 1400s, hundreds of people in Nuremberg, Germany, panicked one day when they saw flying globes battle in the sky and then disappear in a puff of smoke. Historians now believe this was most likely a natural event called a in 1947, there was real fear that aliens could invade Earth. In fact, just nine years earlier, some people believed that martians were attacking New Jersey. They had been listening to a radio play based on the novel The War of the Worlds by H.G. Wells. But some listeners mistakenly believed an alien invasion was actually happening.


UFO Mania

In the years after Arnold’s story made headlines, the number of UFO reports exploded. Farmers saw strange lights over their fields. Kids stargazing in their backyards spotted flying saucers high in the air.

And after a mysterious object was found in the desert near Roswell, New Mexico, rumors spread that aliens had crash-landed there. (An official report stated that a weather balloon—not a spaceship—had crashed near Roswell.)

UFO hunting became a national hobby. People formed clubs to discuss UFO reports. Some of the most popular sci-fi movies and TV shows featured aliens in flying saucers. Sometimes these aliens were sweet. Sometimes they were terrifying.

Meanwhile, the mystery remained: What were people seeing? As with the lines on Mars, was there a simple explanation? Or could it really be aliens?

Secret Planes

Secret Planes



As exciting as that would be, the answer is probably not. After 1945, the U.S. began secretly testing new types of planes. Some were spy planes that could fly in ways no one had seen before. Some could fly without pilots. Some even had a saucer-like shape. 

Many of these tests took place near a secret military base called Area 51. It was in a faraway part of Nevada. That likely explains why many UFOs were seen in the Southwest, not far from Area 51.

Today, experts believe that people who spotted the UFOs were probably just seeing these secret planes. Yet UFO reports have continued to this day. 

Recently, a group of government officials looked into UFO reports from 2004 to 2021. Many of the reports are puzzling. Some are strangely similar to what Arnold had seen in 1947. 

For example, Navy pilots saw spinning objects flying thousands of feet in the air along the East Coast. These objects were seen almost every day from the summer of 2014 to March 2015. They didn’t seem to have engines. How were they flying?

In the end, the officials concluded that we don’t have enough information to know what every UFO might be. Maybe some UFOs are simply birds or balloons. Maybe they are just tricks our eyes are playing on us. Maybe they are a new technology no one knows about yet. Or maybe they really are from another planet. No one knows for sure.

Spy Planes

As thrilling as that would be, the answer is: probably not.

After 1945, the U.S. military was secretly testing many new types of planes. Some could fly without pilots or fly in ways no one had seen before. The A-12 spy plane, for example, could fly faster and higher than anything before it.

Many of these tests took place near a secret military base called Area 51, in a remote part of Nevada. That likely explains why many UFO reports came from the Southwest, not far from Area 51.

In fact, if you lived in the Southwest back then, you might have spotted a UFO too!

UFOs Today

Over the years, details about the secret planes have been made public. Today, experts believe that many UFOs were probably test flights for those planes. Yet UFO reports have continued to this day.

Recently, a group of government officials came together to look into UFO reports from 2004 to 2021. And last summer, this group released its findings. Overall, 144 UFO incidents were analyzed. Many are deeply puzzling. Some are eerily similar to what Arnold saw back in 1947.

In one incident, for example, Navy pilots said that spinning objects appeared at about 30,000 feet over the East Coast. The objects didn’t seem to have engines. How were they flying? Where was their fuel? They were seen almost every day from the summer of 2014 to March 2015.

In the end, the government group concluded that we don’t have enough information to fully understand what every UFO might be. The report did not mention anything about aliens. But it didn’t rule them out either.

Maybe some UFOs are no more than birds or balloons or a drone from someone’s backyard. Maybe they are just light filtering through the clouds—a trick our eyes are playing on us. Maybe, like spy planes from years ago, they are a new technology that most people don’t know about yet.

One thing remains clear: Many of us want to believe in aliens. In fact, 4 in 10 Americans believe UFOs are extraterrestrial, or from outside our planet.

Yet believing something to be true and it being true aren’t always the same thing.

Plane or Flying Saucer?

Spy planes like this one were once top secret. You can see from the plane’s shape that when it was up in the air, it could have been mistaken for a flying saucer.

The Mystery Continues

We may never solve the mystery of what Arnold saw that day in 1947. There is no official explanation. One thing is clear, though: Many of us want to believe in aliens. In fact, 4 in 10 Americans believe UFOs are extraterrestrial, or from outside our planet. 

Every day, astronomers are learning more about outer space and what’s beyond our planet. These scientists use powerful telescopes that can see far into space. They’ve sent special robots to explore Mars.

And each year, astronomers discover new planets. Some of them are billions of miles away. No one knows what—or who—we might find on them. So far, no one has spotted life on another planet. 

But scientists believe that life is out there. It could be discovered in your lifetime. Maybe you’ll be the one to find it!

The Search

Whatever UFOs may be, many scientists do believe that there is some kind of life on other planets. We could even find it in your lifetime.

“One of the most fundamental questions that we ask ourselves is, are we alone?” says astronomer Michelle Kunimoto.

Right now, scientists like Kunimoto are searching the stars for clues. Today, telescopes can see deeper into space than ever before. We’ve sent rovers to explore the surface of Mars. (Alas, no martians were waiting to greet them.)

And it seems like a new planet is discovered almost every day. Scientists believe there could be as many as 300 million planets in our galaxy—the Milky Way—that might support life.

That life probably won’t be what we expect though.

“When people think of life, they think intelligent life like humans and animals and everything that lives on Earth,” says Kunimoto. “But it’s more likely that the first type of life we’ll find will be microorganisms like bacteria.”


The Mystery Continues

So what about Arnold and the strange objects he saw way back in 1947?

No official explanation exists. In an interview in 1950, Arnold gave his own view. He said he believed the objects were “of an extraterrestrial origin.”

We may never solve the mystery of what he saw that day in the bright, sunny skies over Mount Rainier. But Arnold’s story reveals a deeper truth: Human curiosity is powerful. So too is our imagination. 

And whatever is waiting out there in space, it will take both to find it.

Imagining Aliens

Aliens are often shown as green, bug-eyed creatures. But we don’t know what living things on other planets could look like. They could be cat-sized creatures, human-sized blobs, or giant beings. However, most scientists think living things on other planets will be too tiny to see without a microscope!

  • Call on volunteers to read aloud the Think and Read box on page 4 and the Think and Write box on page 9. These support the story’s featured skill, text evidence. Remind students to keep in mind the Think and Read prompt as they read the article.

2. Close Reading

Reading and Unpacking the Text

  • First read: Read the story as a class. Use the Pause and Think questions at the end of each section to check comprehension. 

  • Second read: Project, distribute, or assign the Close-Reading and Critical-Thinking Questions to the class. Preview them together. Ask students to read the article again and answer the questions as a class or in small groups. (Alternatively, assign all or part of the Learning Journey Slide Deck, which contains the questions from this lesson plan and links to the story and Video Read-Aloud.) 

Close-Reading Questions (30 minutes)

  • Read the first section. Why does the author say that Kenneth Arnold saw something that “would change his life—and American history—forever”? (interpreting text) The author says this because Arnold saw flying objects that he believed were alien spaceships. He had never seen anything like them before. Arnold’s story of what he had seen caused Americans to be fascinated by the possibility of aliens on Earth.
  • Read “The Mystery Begins.” What did Arnold see in the sky near Mount Rainier that caused him to believe he had spotted alien spaceships? (text evidence) He saw nine shiny objects that were flying without pilots. The objects darted and flipped in the sky. They were traveling at least 1,200 miles per hour.
  • What happened after a newspaper published an article about what Arnold saw? (cause and effect) After a newspaper published an article about what Arnold saw, other newspapers shared the story. Americans became obsessed with what Arnold had seen. Within a month, people reported seeing more than 850 unidentified flying objects, or UFOs.
  • In “UFO Hunting,” the author writes that “some of the most popular movies and TV shows featured aliens.” What are three examples from the article that support this statement? Where can you find these examples? (text evidence, text features) Answers for the first question should include three of the following: the cartoon character Marvin the Martian, movies like Earth vs. the Flying Saucers, the TV show Star Trek, and the movie E.T. the Extra-Terrestrial. The answer to the second question should be: You can find these examples in “Aliens Through Time.”
  • Read “Secret Planes.” What are some possible explanations for the UFOs people reported seeing? (key idea) The UFOs that people saw could have been new types of planes the U.S. began testing after 1945. They could also be birds, balloons, new technology, or tricks our eyes play on us.
  • Why do you think “The Mystery Continues” is the title of the next section? What would be another good title for it? (main idea, expressing an opinion) The section has this title because it is mainly about how humans are still looking for answers about living things from other worlds. There is still no official explanation for what Arnold saw in 1947. Scientists believe there is life on other worlds, but no one has spotted life on another planet yet. Answers to the second question will vary.
  • Look at the pictures on page 9 and read the caption. What do you learn about what living things on other planets might look like? (key details, text features) The caption explains that living things on other planets could be small creatures, human-sized blobs, or larger beings. But most scientists think living things on other planets will be too small to see without a microscope.

Critical-Thinking Questions

  • At the end of the article, the author says, “But scientists believe that life is out there.” What do you believe? Do you think there is life on other planets? Use details from the article to support your answer. (text evidence, expressing an opinion) Answers will vary.

List words and phrases from the article (e.g., plane, aliens, strange, objects, shiny, saucer-like, mysterious, spaceships, Martian, bug-eyed, astronomers) for students to refer to and ask them to describe what they see. How are the images similar or different? What do students usually picture when they think of aliens?

For Advanced Readers

Have students work in groups or pairs to write a one-paragraph newspaper article about any of the UFO incidents or sightings mentioned in the story. Students should include a headline, subhead, and an illustration of the UFO.

For STEAM Learning

Many different UFOs and possible alien forms are described in the article. Ask students to choose one and create an illustration that captures the details in the article. Students can draw their illustrations, make them with collage materials, or even create a diorama. Invite students to share their artwork in a classroom gallery.
