UFO sightings taken seriously by the US government

The Pentagon made a splash in recent years with revelations of videos showing fighter pilots observing unknown aerial objects. Lindsey uncovers stories of still-unverified UFO sightings and addresses the likely possibility of life beyond Earth.

From the most shocking accounts of abductions and UFO sightings to an interview with a Harvard professor about these claims, dive into fascinating stories about run-ins with ETs that have continued to be told for decades.

Area 51 is a highly classified US military facility located in Nevada. Because of its remote location and secrecy, many Americans have speculated that the location hosts aliens. However, critics of this theory believe the UFO sightings are actually just military aircraft.

On Feb. 24-25, 1942, weeks after the Pearl Harbor attack, a US military radar warned of enemy aircraft. A citywide blackout went into effect, powerful searchlights were lit up, and US forces fired artillery at what they believed to be the enemy. However, no confirmed enemy planes were ever identified. Eyewitnesses reported seeing large objects flying overhead, and much of the public speculated about UFOs and extraterrestrial attacks.

The appearance and downing of a Chinese surveillance balloon brought the concept of high-altitude floating aircraft into the public consciousness. While sparking a diplomatic row, it also revealed how many objects—nefarious or benign—are...

Established in 1958—a year after the Soviet Union launched Sputnik 1—the National Aeronautics and Space Administration has taken humanity into outer space and helped reveal the nature of the universe. Historic moments include the Apollo 11 mission putting humanity on the Moon and construction of the International Space Station.

In late January 2023, a Chinese high-altitude balloon, believed to be for surveillance purposes, traversed the US and caused a diplomatic stir. The technology itself is established—though typically used for atmospheric measurements. This visual...

From the D.B. Cooper plane hijacking to the kidnapping of Frank Sinatra Jr. to the details about the first FBI agent killed in the line of duty, this FBI archive overviews the agency's most famous cases. Cases are organized by investigative priorities, according to the agency. Clicking any of the linked investigations takes readers to detailed articles about the cases, some of which remain unsolved.

The launch of Sputnik 1 in 1957 jolted US political leaders, who urgently consulted scientists and defense experts on how to respond. Concerns about Soviet technological dominance—and the promise of civilian space applications—led directly to NASA’s creation in 1958.

Let us to take you back through the timeline of space exploration and its rich, fascinating history, starting in 1946, with a rudimentary German military rocket.

From the Wright brothers' flight of the first powered plane in 1903 near Kitty Hawk, North Carolina, to SpaceX's debut of the Falcon 9 rocket in 2010 with reusable boosters, this interactive shows off the technological evolution of flight, from mechanical propulsion to ballistic spaceflight.

The US launched Project Paperclip in 1946, covertly recruiting over 1,500 German scientists to advance American military and space programs. Among them was Wernher von Braun, a key architect of the V-2 rocket who later became instrumental in NASA’s Apollo missions. While these scientists accelerated technological breakthroughs, their recruitment raised moral debates about overlooking wartime affiliations in the name of progress—questions that remain unresolved today.

Within a decade of LSD's discovery, the US government had launched a secret initiative involving hypnosis and hallucinogens. LSD researcher Louis Jolyon West conducted experiments for the CIA's MKUltra project, which focused on the potential of mind control. He later took part in a criminal trial that hinged on testimony whose sourcing was seemingly inspired by MKUltra experiments. This article explores light shed by West's personal archive.

This 1957 news report captures the shock and uncertainty that followed the launch of Sputnik, showing how the first artificial satellite immediately altered global politics, military planning, and public perceptions of technological power.

This interactive timeline chronicles the space race from its Cold War origins to the moon landing, highlighting key figures, pivotal moments, and rapid technological advancements. It combines archival photos, video, and links to related material.

The series illustrates the population of objects orbiting Earth as of February 2024, using data from US Space Command. These include active satellites, defunct spacecraft, rocket bodies and debris fragments larger than roughly 10 centimeters in low Earth orbit.

Psychedelics' modern era began when LSD was discovered in the 1930s. By the 1950s, clinical trials were underway. US user experimentation outside of medical settings (and high-profile violence, like the Manson murders) inspired negative attitudes toward psychedelics, leading to use restrictions that prohibited companies from patenting psychedelic compounds. This strangled psychedelics' profitability until the 1990s when the government loosened its grip and psychedelics research began seeing a resurgence.

While accounts of military strategists using uncrewed hot air balloons for attacks and surveillance exist from the 19th century, the first use of drones as a modern concept began in World War I with a radio-controlled propeller craft. This online...

Some rumors about the event became perceived as more reliable than the Soviet mass media, which had omitted key information during the early days of uncertainty. The resulting theories included CIA involvement in the disaster, three-headed birds, aliens, and a weaponized earthquake.

In addition to being a massive asset to journalists and eager members of the public, FOIA has also shed light on some of the weirder corners of America’s functioning democracy. Here are 10 choice documents.

Created by Congress under the National Aeronautics and Space Act, NASA officially began in 1958, building on earlier aviation research and positioning the US to compete in the Space Race and lead global space exploration.

The US government adopted the new technology to support the development of the Apollo Guidance Computer, which would help astronauts fly to the moon. This drove manufacturing up and costs down, setting the stage for the modern computing era.

The document proposed a future weather modification system to achieve military objectives, but clarified that such a system "does not reflect current military policy, practice, or capability." Past testing of biological and chemical weapons has accelerated conspiracies about streaks of condensation trailing aircraft to be harmful chemical agents.

Avid fans of archaeology can sometimes fall prey to unsubstantiated claims like "aliens built the pyramids," provocative, dubious theories which fall under the category of pseudo-archaeology. Many of these claims are premised on hidden biases toward non-Western cultural heritages. This professor explores the hidden contours of pseudo-archaeology in this 12-minute TED talk.

Theorists have long believed that sudden increases in pizza deliveries near the Pentagon signal a major event is about to occur. Historical examples include the CIA ordering 21 pizzas the day before the beginning of the Gulf War, and another surge of deliveries before former President Bill Clinton's impeachment hearings. Citizens have since begun monitoring food orders in the area. See a tracker of Pentagon pizza orders here.

Many such compounds (including LSD, psilocybin, and more) are classified as Schedule I drugs—illegal to possess and federally regarded as having no medical use. Researchers say such restrictions have created significant hurdles for formal clinical trials. With this executive order, the FDA will enable work particularly focused on depression, PTSD, and alcohol use disorder.
