Roswell Incident

In June 1947, a rancher in Roswell, New Mexico, found strange metallic debris in a field. Soon after, military personnel from a neighboring air base gathered all the evidence and announced they had recovered a flying disc . The following day, however, they retracted their statement, claiming instead that the debris was part of a weather balloon — and suspicions of a conspiracy were born

Years later, government officials stated that the balloon story had been a cover, but there are still disputes about what actually happened. Military sources have since said the balloon was part of a program to detect Soviet nuclear weapons , but the contradicting stories have led many to believe that we don’t know the whole truth about the incident.

Washington, D.C. UFO Incident

In July 1952, a series of UFO sightings in Washington, D.C., was reported over two consecutive weekends near the White House and the Capitol. These objects were seen visually by pilots and air traffic controllers, and they were also tracked by radar.

Though the air force deployed jets to intercept the UFOs, the pilots reported that these objects had incredible speed and that they were easily outmaneuvered. The incident sparked attention from the media, which led President Truman to create the Robertson Panel, a scientific committee dedicated to investigating UFO sighting reports.

Cash–Landrum incident

In December 1980, Betty Cash and Vickie Landrum, alongside Landrum’s grandson, spotted what they initially thought was an airplane near Dayton, Texas, but was actually a diamond-shaped object, emitting a bright light and hovering near the ground . After getting out of their vehicle to inspect the object, they returned to the car to find it was extremely hot to the touch.

After the alleged UFO left, Cash and Landrum claimed to have seen a military aircraft following it. The three of them experienced burns, nausea, and other symptoms similar to those of radiation sickness , and Cash spent a month hospitalized. The government denied any involvement in the situation, but many investigators and researchers believe this could have been a secret military experiment.

The Westchester Boomerang

From 1983 to 1984, residents of Hudson Valley in New York and Fairfield County in Connecticut reported the appearance of large objects that emitted bright lights , flying in a circle or V-shaped formation.

The police later claimed that these were actually a group of Cessna 152s from a neighboring town , and the alleged pilots expressed their amusement at the confusion. However, witnesses claimed that the flying objects could not have been small aircraft, as they made no sound and were able to hover in one spot for extended periods of time.

5

Travis Walton incident

On November 5, 1975, Travis Walton, a logger working in Heber, Arizona, was reported missing by his crew. They claimed that, returning from work, they had stopped because they saw an unusual light. Walton had walked into the forest following it and had been struck by a beam . Afraid that he had died, his companions fled and alerted the police, but Walton was not found despite intense searches.

Five days later, Walton appeared in Heber, confused and disoriented. He claimed to have been abducted by humanoid aliens, who kept them in their aircraft . He and other witnesses passed the lie detector test, but many people believed the incident was an elaborate hoax.

Kenneth Arnold UFO sighting

In June 1947, Kenneth Arnold, a pilot flying near Mount Rainier in Washington State, reported sighting of several flying objects, which he believed were experimental military aircraft. After an investigation by military officials, they found several witnesses who reported sightings at a similar time and location to Arnold.

Arnold described these aircraft as round objects that moved as a "saucer would if you skipped it across the water". The popularity of the story, the first UFO sighting after World War II, first popularized the term "flying saucer."

7

Stephenville, Texas sighting

Residents of Stephenville, Texas, reported in January 2008 that they had seen a massive flying object, moving at high speed and emitting lights. The witnesses, including a pilot and a police officer, claimed the object was up to a mile long and made no sound.

Though the U.S. Air Force initially denied having planes in the area , they later explained that training maneuvers for 10 F-16 jets had been conducted; this contradiction sparked rumors of a classified military aircraft.

8

Marfa Lights, Texas

One of the oldest alleged sightings in America, the first record of the Marfa lights dates back to 1883. These light orbs appear sporadically on the horizon, and their color varies between blue, red, and white. Appearing around 30 times a year, the Marfa lights can still be seen to this day.

Scientists have tried to explain these appearances as an atmospheric phenomenon similar to a mirage, or the reflection of car lights from a highway, but they have failed to reach a definite conclusion. Marfa has become a popular destination for UFO aficionados , which has led the Texas Department of Transportation to build a dedicated viewing area.

Japan Airlines Cargo Flight 1628

On November 17, 1986, the crew of a Japanese cargo plane claimed to have been followed by three flying objects —one massive and two smaller ones— as they flew over Anchorage, Alaska. Media outlets reported that these objects had been captured on a military radar, but government officials later discredited the claims.

After landing in Anchorage, the crew was interviewed by the FBI and the CIA, who allegedly confirmed a radar sighting. However, the agencies have since denied that the meeting ever took place.

10

USS Nimitz "Tic Tac" incident

In November 2004, jet pilots from the USS Nimitz aircraft carrier reported encountering a ‘tic tac-shaped’ object with remarkable flying capabilities. Besides the eyewitnesses, the object was captured by the jets’ cameras and tracked by the radar of another aircraft carrier for two weeks.

The videos were classified until 2020, when they were released by the Pentagon after a series of reports by the New York Times . Though several theories have been postulated, there is no official explanation for this incident.

The Moon landing (July 20, 1969)

The moment Neil Armstrong set foot on the lunar surface, he had millions of eyes upon him across millions of TV screens. Considered the television event of the decade, t he July 20, 1969 Moon landing broke records at a national and international level. Gathering an estimated 600 to 650 million viewers worldwide, "the small step for man, giant leap for mankind" was watched by around 125 to 150 million American viewers, representing around 93% of households with a TV. This record was not surpassed until the 1981 wedding of Lady Diana and Prince Charles.

"Day of Infamy" speech (December 8, 1941)

A day after the December 7, 1941 attack on Pearl Harbor by the Japanese Imperial Navy, President Franklin D. Roosevelt addressed the U.S. Congress during a joint session. His speech, which started by describing the day before as "a date which will live in infamy", was not meant to convince Congress about declaring war —which it did shortly after—but to rally a distressed and shocked nation. One of the most famous political speeches of all time, this address attracted the biggest radio audience in American history, with more than 100 million people (an estimated 81% of the adult population) tuning in.

The first Kennedy-Nixon debate (September 26, 1960)

The first of the 1960 presidential debates between Senator John F. Kennedy and Vice President Richard Nixon does not hold the record for the most viewed debate of the century (held by the 1980 Carter-Reagan debate), but it’s nonetheless a landmark event in American television. The first televised presidential debate ever, it attracted between 66 and 77 million viewers , and it is considered one of the main reasons for the shift in public opinion in favor of Kennedy. Nixon, aged 47, the leading candidate before the broadcast, appeared exhausted and pale compared to the much younger-looking and more telegenic Kennedy, aged 43.

"I have a dream" speech (August 28, 1963)

The date and location of Martin Luther King Jr.’s most famous speech were not accidental. As part of the marches in support of President Kennedy’s proposed civil rights legislation, it coincided with the centennial of the 1863 Emancipation Proclamation made by Abraham Lincoln, at whose memorial King gave his speech. Besides the massive live audience (around 250,000 people), the speech was broadcast by the three major television networks and by major radio stations in the country . Although there are no official numbers recorded, it is estimated that there were millions of viewers and listeners, including the First Family at the White House.

The War of the Worlds broadcast (October 30, 1938)

On October 30, 1938, CBS Radio Network broadcast a radio adaptation of H. G. Wells' The War of the Worlds , directed and narrated by Orson Welles. The first part of the broadcast was delivered as a realistic news broadcast, with reporters breaking the news about an alien invasion, which led part of the audience to panic and believe that an actual invasion was taking place. The episode had an estimated audience of 6 million, and it is thought that more than a million listeners believed it was a real broadcast.

6

The Beatles’ first U.S. television performance (February 9, 1964)

The most famous British band of all time made their American TV debut on February 9, 1964, on The Ed Sullivan Show , with an audience of 73 million viewers. The performance was highly anticipated —the broadcast network received 50,000 applications for the 728 seats available in the studio— and it is considered the starting point of American Beatlemania and the so-called "British invasion" of American music.

FDR's first Fireside Chat (March 12, 1933)

In the 1930s, during the Great Depression, the radio became one of the main sources of entertainment and news. President Roosevelt’s Fireside Chats used the radio format as a way to connect directly with millions of weary Americans , explaining the policies that were being implemented to combat the crisis, dispelling rumors, and encouraging them to trust in the government. The friendly, informal tone of these broadcasts was highly effective in raising the nation’s morale and reducing general anxiety. With the first broadcast reaching an audience of 60 million, the Fireside Chats attracted more listeners than most of the popular radio shows, with numbers rising as America entered World War II.

Nixon’s resignation speech (August 8, 1974)

On August 8, 1974, President Nixon addressed the American public from the Oval Office to announce his decision to resign the following day as a result of the Watergate scandal and under the threat of an impending impeachment. Besides an ample radio audience, the televised speech was watched by 90 to 110 million television viewers. While the reactions of the public were mixed, the speech had an unprecedented impact and is considered one of the most important political speeches of that era.

_Roots_’ final episode (January 30, 1977)

The production and broadcast of the 1977 Roots miniseries was a milestone in itself. Only a few years before, tensions around the Civil Rights movement had shaken America, and some thought that airing a story that put the enslavement of Black people in the spotlight was a huge risk. But audience numbers proved them wrong: with around 29 million households tuning in for the first episode, the series became a cultural phenomenon that sparked conversations about race, ancestry, and American history. The final episode, with more than 100 million viewers —more than half of the U.S. population— was the most-watched TV episode of the time, and the second-most-watched overall series finale in U.S. history.

Super Bowl XVI (January 24, 1982)

Nowadays, it’s not surprising that sports events like the Super Bowl have a huge television audience, but things were different in the 1980s. Super Bowl XVI, played on January 24, 1982, in Michigan, with the San Francisco 49ers facing the Cincinnati Bengals, was watched by more than 85 million people, breaking all broadcasting records of the time .

11

Louis-Schmeling rematch (June 22, 1938)

When Joe Louis faced the German boxer Max Schmeling for the first time in 1936, everyone predicted that Schmeling would lose against the undefeated and rising Louis. To the world’s surprise, Schmeling won by knockout. Their rematch two years later was not only Louis’ opportunity to change the result and defeat Schmeling , but it was also charged by the increasing political tensions between Hitler’s Germany and the U.S. Besides its huge live audience at Yankee Stadium, the fight had a record audience of 70 million people in America, with an additional 30 million estimated listeners from other countries.

"One small step" vs. "Man, that may have been a small one…"

Neil Armstrong stepped onto the lunar surface with his carefully planned line: "That is one small step for a man , one giant leap for mankind." Pete Conrad from Apollo 12 decided to have some fun with that.

Conrad was short, and he had bet a reporter five hundred dollars that he could say whatever he wanted when he stepped down. This is the line he went for, as documented in NASA transcripts: "Whoopie! Man, that may have been a small one for Neil, but that is a long one for me ."

Apollo 12 and the lightning strike that tried to end everything

Apollo 12 was struck by lightning not once but twice, only 36 seconds after launch. The electrical surge wiped out telemetry in Mission Control.

The flight looked doomed until flight controller John Aaron said the now legendary instruction: "Try SCE to Aux." Conrad responded with, "What the hell is that?" because almost no one remembered what SCE meant.

Luckily, Alan Bean understood what to do. He flipped the switch, the instruments rebooted, and Apollo 12 kept flying.

3

Apollo 13 was just as dramatic as the movie showed

The explosion of an oxygen tank in Apollo 13’s service module really did turn the mission into a race against time. The line "Houston, we have a problem" is Hollywood’s adaptation, however. The real line, spoken by Jack Swigert and repeated by Jim Lovell, was "Houston, we have had a problem."

Other real drama: the crew used the Lunar Module as a lifeboat, battled rising CO₂ levels, manually aligned the spacecraft using Earth’s horizon, and returned home with only a sliver of battery life left.

Apollo 16 astronauts drove a moon rover like teenagers with a new car

The lunar rover was a marvel: lightweight, foldable, and capable of reaching 13 to 18 km/h depending on conditions.

John Young and Charlie Duke from Apollo 16 were so thrilled with it that Mission Control had to repeatedly remind them not to drive too fast on uneven terrain.

Duke even recorded one of the wildest moments of the program when Young yelled, "Look at that… look at that!" as dust flew up behind them.

5

The dust that drove astronauts nuts

Moon dust is sharp, sticky, and electrostatically clingy. Astronauts from Apollo 11 onward complained that it smelled like burnt gunpowder and got everywhere. Harrison Schmitt from Apollo 17 suffered "lunar hay fever" after breathing dust tracked into the cabin.

NASA later became mildly obsessed with studying how dangerous that dust might be… and it turns out it is genuinely abrasive to suits and could be risky to lungs.

6

Apollo 11 and the computer that said "nope"

Just minutes before landing on July 20, 1969, the Apollo Guidance Computer flashed a "1202" program alarm. In non-NASA terms, the computer was overloaded and essentially panicking .

But guidance officer Steve Bales had trained for this exact situation and cleared the crew to proceed. Armstrong later said this call was one of the mission’s most decisive moments. So yes, the first Moon landing almost got canceled by a stressed-out computer.

7

The golf shot that echoed through history

On Apollo 14, Alan Shepard smuggled a makeshift golf club head along with two golf balls.

On the moon, he attached it to a sample collection tool and made the most famous swing in the Solar System. The ball truly did travel far, although probably not the "miles and miles" Shepard joked about. Still, it remains the only round of lunar golf ever played.

8

Apollo 15’s postal controversy

The Apollo 15 astronauts carried unauthorized stamped envelopes to sell to collectors later.

This became a scandal when the deal came to light. NASA was furious, the crew was reprimanded, and the agency tightened rules on what astronauts could take to space.

The event is fully documented and remains one of the strangest side stories of the program.

Twelve people walked on the moon

Between 1969 and 1972, exactly twelve astronauts walked on the lunar surface.

The list, in chronological order, is: Armstrong, Aldrin (Apollo 11), Conrad, Bean (Apollo 12), Shepard, Mitchell (Apollo 14), Scott, Irwin (Apollo 15), Young, Duke (Apollo 16), and Cernan and Schmitt (Apollo 17). Cernan remains the last human to have walked on the Moon.

10

The last moonwalk included a love letter

During Apollo 17, Gene Cernan traced his daughter’s initials TDC on the lunar dust.

As he said his farewell words on the Moon, he hoped the world would continue exploring. His last line: "We leave as we came and, God willing, as we shall return, with peace and hope for all mankind."
