Trans-Medium Behavior: A Data-First, Taxonomy-Based Framework for Validating Air–Water Claims

To the point

Trans-medium behavior is the idea that some alleged air–water crafts can move between air and water without losing performance, but there is no conclusive evidence, so a data‑first, multi‑sensor approach uses physics and a standard taxonomy to separate confirmed capabilities from misidentifications, with Aguadilla 2013 and GoFast 2015 cases leaning toward ordinary explanations rather than true air–water vehicles.
