UAPx

UAPx is a U.S. nonprofit research organization founded around 2020 by Navy veterans of the 2004 Nimitz-era events, including Kevin Day (the Princeton radar operator) and Gary Voorhis, with physicists joining to run instrumented field studies of UAP.

The founders' military encounters supplied motivation; partnerships with academic physicists, notably Matthew Szydagis (University at Albany) and Kevin Knuth, supplied method.

UAPx mounts expeditions with multi-sensor kits (optical, infrared, radiation, magnetometry), most famously a July 2021 Catalina-adjacent deployment filmed for the 2022 documentary A Tear in the Sky. Its scientists have published peer-reviewed methodology papers describing custom software (including the NightHunter detection pipeline) and candidate-analysis frameworks, reporting ambiguities rather than claims: the group's published posture is that most captures resolve and a residue lacks data, with follow-up campaigns continuing through the 2020s.

Active at modest scale, one of the small ecosystem of instrumented-search efforts alongside the Galileo Project's observatories and SCU's analyses.

Skeptics have criticized the documentary's dramatized framing (its "portal" language outran the data, and Szydagis publicly clarified the science team's cautious reading), which the group's own papers implicitly answer. Funding scale limits statistical power, a constraint UAPx acknowledges. Its persistence in publishing negative and ambiguous results earns cross-camp respect uncommon in the field.
