// WEIGH THE EVIDENCE

Explained vs. Unexplained

Good disclosure means looking at both sides. Most UFO reports turn out to be something ordinary — but a small number, often recorded by several sensors and trained observers at once, have never been explained.

What most sightings turn out to be

  • Balloons — the single biggest category in government reports.
  • Drones — increasingly common since the 2010s.
  • Satellites — e.g. Starlink “trains” of moving lights.
  • Aircraft & flares — seen from unusual angles or at night.
  • Birds, planets & stars — Venus is a classic.
  • Sensor artifacts — glare, parallax and camera rotation can make ordinary objects look impossible.
“AARO found no evidence that any USG investigation … has confirmed that any sighting of a UAP represented extraterrestrial technology.” — AARO Historical Record Report, 2024

Why the mystery won’t go away

  • Multi-sensor cases — radar, infrared and trained eyewitnesses agreeing on the same object.
  • Reported performance — sudden acceleration, no visible propulsion, no wings, hovering in high winds.
  • Credible witnesses — military pilots, radar operators and intelligence officials, under oath.
  • Unresolved reports — hundreds of government cases remain “uncharacterized”.
  • Secrecy — decades of classification, and whistleblowers alleging hidden programs.
  • Congress — bipartisan lawmakers continue to push for full records release.
“UAP clearly pose a safety of flight issue and may pose a challenge to U.S. national security.” — ODNI Preliminary Assessment, 2021
