The investigation continues into two unusual high-altitude encounters initially described as unmanned aircraft systems (UAS) or drone sightings. Information gathered since the Flight Safety Detectives’ first look at this incident has made these strange events seem like unidentified anomalous phenomena (UAP) incidents.

In December 2024, a Delta 767 crew reported being shadowed for over an hour at 34,000 feet by multiple flashing red-and-white aircraft over New Mexico and Arizona—well above legal drone limits and invisible to ATC radar. FAA records later indicated four objects maneuvering close to the jet, one within 1,000 feet.

Shortly after, a United 787 at 27,000 feet had a brief, separate encounter with a similar object. FOIA requests revealed details that made these cases more consistent with UAP (Unidentified Anomalous Phenomena) than drones, given their altitude, endurance, and performance.

Greg Feith, John Goglia, and Todd Curtis discuss aviation safety concerns, the FAA’s lack of a dedicated UAP reporting system, and the stigma pilots face in reporting such events. Todd plans to mine FAA drone-incident data and Mandatory Occurrence Reports to identify other likely UAP encounters.
