Aguadilla Airport Infrared Video
A US Customs and Border Protection surveillance aircraft captures infrared footage of an unidentified object near Rafael Hernandez Airport in Aguadilla, Puerto Rico. The object appears to enter and exit the ocean without losing speed and at one point seems to divide into two separate bodies.
Background
On the night of April 25, 2013, a DHC-8 Dash 8 turboprop aircraft operated by the US Department of Homeland Security's Customs and Border Protection division recorded an unidentified object near Rafael Hernandez Airport in Aguadilla, Puerto Rico, displaying anomalous thermal and transmedium behaviors.
The infrared footage, approximately three minutes long, has been analyzed as evidence of transmedium UAP behavior that exceeds conventional technology.
The Incident
A DHC-8 Dash 8 turboprop aircraft was preparing for a routine patrol near Rafael Hernandez Airport in Aguadilla, on the northwestern coast of Puerto Rico.
The airport occupies the site of the former Ramey Air Force Base, a Strategic Air Command installation active during the Cold War.
The crew's thermal imaging system recorded an object that initially appeared over the Atlantic Ocean and moved toward the airport at an estimated speed between 80 and 120 miles per hour.
Key Observations
The thermal signature indicated the object was cooler than the surrounding environment, contrasting with what would be expected from a craft employing standard propulsion systems.
No exhaust plume, rotor wash, or other thermal byproduct was detected at any point during the recording.
The footage documents the object's apparent transmedium behaviour: entering the ocean surface and re-emerging without any visible deceleration, change in thermal profile, or splash effect.
At another point, the single object appears to separate into two distinct returns that continue on independent trajectories.
Analysis
The video was leaked to the public in 2015 and analyzed by the Scientific Coalition for UAP Studies, a civilian research organization.
Their published report calculated speeds, altitudes, and trajectories from the FLIR display data.
They concluded that the object's performance envelope exceeded that of any identified conventional technology.
Significance
Both the water-entry capability and the apparent fission were identified by analysts as behaviors not associated with any known aircraft, drone, or natural phenomenon.
The case has become a frequently cited example of transmedium UAP behaviour.
This category received particular emphasis in the 2021-2022 US Congressional discussions on unidentified aerial phenomena.

Significance
The Aguadilla footage represents one of the clearest recorded examples of apparent transmedium capability — the ability of an object to transition between air and water without observable loss of performance. Captured by a government surveillance platform with calibrated infrared sensors, the video provided measurable data that enabled independent scientific analysis. The case significantly contributed to the incorporation of transmedium behaviour as a defining characteristic in the US government's evolving framework for categorising UAP.
