A high-resolution video showcases an underwater object exceeding the size of an offshore oil derrick while moving at extraordinary speeds of 450 to 550 knots. This observation highlights the existence of unidentified anomalous phenomena (UAP) that are not confined to one medium, indicating their trans-medium capabilities. The term UAP underscores the multi-domain nature of these phenomena, as they can traverse different environments and challenge our understanding of such occurrences.
