How to judge UFO evidence: pilots, researchers and astrophysicists compare notes

September 29, 2026 · 18 min read

A Navy pilot describes what he saw, Jacques Vallée explains how to analyze physical evidence and how radar can mislead, and Adam Frank sets a scientist's bar for proof. Together they offer a practical framework for separating the unexplained few percent from noise.

12 questions on this insight. Answer in your head, then open the card.
What share of UFO reports does Jacques Vallée say have ordinary explanations? Show answer

About 95 percent, in line with France's official investigators; these are rarely hoaxes, just genuine misperceptions.

What working method do the three experts' views add up to? Show answer

Expect the ordinary, check how each sensor can fool you, demand multiple witnesses, physical traces and calibrated instruments, and keep what survives.

What did Ryan Graves's squadron detect after its radar upgrade around 2014? Show answer

Objects over the water that older radars missed, confirmed on infrared and weapons systems, yet invisible to pilots within about 500 feet.

How did Graves handle the rumor that drones were hunting a loose nuke? Show answer

He checked with contacts who work on weapons of mass destruction, who said there was none, and explained why drones would be poor tools for that search.

Why does Graves say so many sightings stay unresolved? Show answer

Law and bureaucracy: the government must presume a citizen may be flying the objects, requiring warrants and high-level approvals to intercept or shoot down.

How can radar mislead observers, according to Vallée? Show answer

A radar feedback device can send false signals that make a small plane look like a large one elsewhere, or seem to vanish and reappear.

Why does Vallée say the Tic Tac is not a photograph? Show answer

It is an infrared image from a pod designed to read the heat signature of enemy exhaust, not to track unknown objects.

What kinds of cases does Vallée give the most weight? Show answer

Those with several independent witnesses and physical traces that can be analyzed, such as Socorro, as opposed to artwork or single accounts.

What did the analysis of the 1977 Iowa metal show about method? Show answer

Samples were tested on two instrument systems and reviewers demanded a year of extra work before publication, which Vallée treats as validating the method.

What standard does Adam Frank apply to claims of non-human technology? Show answer

The same harsh scrutiny as any scientific discovery, with calibrated and fully characterized instruments; he says no evidence so far comes close.

What does Frank think UAPs most likely are? Show answer

As a bet, peer-state adversaries probing each other's radar.

How does Thomas Campbell's view differ from the others? Show answer

He thinks a larger consciousness system could create such experiences and even traces, and that personal experience is its own truth, which no sample can test.

This is the short form. The full insight has every expert's reasoning, their own words and the sources.
