Expand all Collapse all UFO Noises What Do UFO Witnesses Hear? People who report UFOs often describe more than lights in the sky. A recurring feature in many sightings is sound: humming, buzzing, clicking, roaring, whistling, metallic vibrations, low-frequency droning and, in some cases, complete silence where noise would normally be expected. 91 pages Read more Aircraft When Aircraft Sounds Become UFO Stories Jets, helicopters, drones, and propeller aircraft can sound unfamiliar when distance, weather, and darkness change perception. 6 pages +Show subtopics Read more Flight Checks How to Check a Strange Aircraft Sound Flight activity records can often turn a strange roar or hum into a traceable aircraft, helicopter, cargo flight, or training operation.
