Unresolved Signals

On January 13, 1981, on United States Air Force letterhead, a deputy base commander typed two words at the top of a one-page memorandum and sent it to the British Ministry of Defence. Unexplained Lights. The memorandum was unclassified. It described a pulsing red light that maneuvered, broke into five separate white objects, and was seen by three patrols across two nights at Royal Air Force Bentwaters and Royal Air Force Woodbridge...

On August 9, 1966, three months before the Condon Committee began its formal work, the committee's own coordinator sat down at a typewriter and produced a one-page memorandum. He addressed it to two senior administrators of the University of Colorado. He called it "Some Thoughts on the UFO Project." He surveyed the internal politics. He laid out the case for the school accepting the Air Force contract. He used the wor...

Two weeks ago on this show, we told you about eight scientists. Today the public count is eleven. Two weeks ago the FBI had said nothing on camera. Last Sunday the Director of the FBI sat on Sunday Morning Futures and confirmed the investigation. Two weeks ago NASA had said nothing in public. This week, for the first time on the record, a NASA spokesperson told Gizmodo "at this time, nothing related to NASA indicates a national sec...

For as long as we've been human, we've been seeing things in the sky we can't explain. Navy pilots. World War Two pilots. Medieval monks. The hands that painted the caves.

Every official investigation, from Project Blue Book to AATIP, was shut down, redacted, buried. And since 2024, eleven people with inside knowledge have turned up missing or dead. A NASA JPL engineer. An Air Force aerospace scientist. Two from Los Alam...

In January 1953, the Robertson Panel told the Air Force to debunk, classify, and criminalize the UFO record. Thirteen years later, a Michigan congressman stood on the House floor and told the country the Air Force's latest explanation was flippant. What happened in between is not a cover-up. It is a pencil mark. Under the five directors who followed Captain Edward Ruppelt, the percentage of cases the Air Force listed as "unidentifi...

Over four days in January 1953, five physicists sat in a secure Pentagon conference room and reviewed twenty-three UFO cases out of the two thousand three hundred and thirty-one in the Air Force files. Twelve hours of formal meeting time. One percent of the evidence. At the end, the panel unanimously concluded that UFOs were not a physical threat to national security, and that the real problem was the public's interest in them....

Edward Ruppelt rebuilt the Air Force's UFO investigation from the ground up. In late 1951, Lieutenant General Charles P. Cabell held an emergency Pentagon briefing after radar incidents at Fort Monmouth, New Jersey. He tore down the discredited Project Grudge and authorized a complete overhaul. The man he chose was a thirty-year-old captain with two Distinguished Flying Crosses and a degree in aeronautical engineering.

In the late summer of 1948, Project Sign analysts at Wright-Patterson Air Force Base finished a Top Secret document called the Estimate of the Situation. Its conclusion: the objects were real, not American, not Soviet, and likely extraterrestrial. General Hoyt Vandenberg rejected it, cited lack of physical proof, and ordered every copy destroyed. The Air Force later denied it had ever existed.

This episode traces the full arc of...

In September 1946, an object over Florence, Italy, changed direction in the sky. It was visible for ninety seconds. Meteors do not turn.

This episode follows the phenomenon as it spreads across thirteen countries in thirty days, from the mountains of Greece to the skies over North Africa. Five governments launched classified investigations. All five reached the same conclusion: the objects were real, structured, and could not be exp...

Over the past twenty months, eight people connected to aerospace, nuclear research, advanced propulsion, and defense science have died or disappeared in the United States. Two members of Congress have spoken publicly about the pattern. A former FBI assistant director has alleged coordination.

Three of the eight cases are solved with confirmed, mundane explanations. Five remain open — and those five share features that the statistica...

In November 1948, Swedish Air Intelligence told visiting American officers that the objects over Scandinavia represented "a high technical skill which cannot be credited to any presently known culture on earth." That document stayed classified for forty-nine years.

This episode tells the story behind that conclusion. Six months before Kenneth Arnold, before Roswell, before a single flying saucer was reported over the United States, ...

On September 23, 1947, a three-star general sent a classified memo to the Pentagon confirming that unidentified objects in American airspace were "something real and not visionary or fictitious." Three months earlier, the U.S. Army had announced — then retracted — the recovery of a flying disc in Roswell, New Mexico. In between, the FBI launched a secret joint investigation with Air Force intelligence, and the President signed the ...

Episode 1: From Babylonian cuneiform to Pentagon whistleblowers, we trace the UAP record across seven languages, thousands of years, and every continent.

Ancient Akkadian tablets describe objects in the sky that their scribes couldn't explain. Sanskrit epics detail flying vehicles called vimanas in texts thousands of years old. The Book of Ezekiel records a vision of wheels within wheels that has puzzled scholars for millennia. A 15...
