Aguadilla Airport UAP

April 25, 2013 — Rafael Hernandez Airport, Aguadilla, Puerto Rico

The Event

On the night of April 25, 2013, a US Department of Homeland Security / Customs and Border Protection (CBP) DHC-8 surveillance aircraft was preparing to land at Rafael Hernandez Airport in Aguadilla, Puerto Rico when the crew detected an unknown object. The airport tower had briefly shut down due to the object, delaying the CBP aircraft's landing.

Thermal Video

The CBP aircraft's infrared camera captured approximately three minutes of footage showing a small, dark object (cold relative to the environment) traveling at approximately 80-120 mph at low altitude. The object exhibited no visible propulsion, wings, or control surfaces. Analysis of the video revealed the object maintained a consistent, controlled flight path despite varying terrain and conditions.

Trans-Medium Travel

The most remarkable aspect of the footage occurs when the object enters the ocean. Rather than impacting the water or slowing down, the object smoothly transitions from air to water travel, submerging and re-emerging multiple times without any apparent change in performance. At one point, the object appears to split into two separate objects while underwater, before both exit the water and continue flying.

Analysis

The video was analyzed by the Scientific Coalition for UAP Studies (SCU), a group of scientists and engineers. Their detailed report concluded that the object's behavior was inconsistent with any known aircraft, drone, bird, or natural phenomenon. The trans-medium capability — seamlessly transitioning between air and water — is one of the five observable characteristics of UAP identified by the US intelligence community in their 2021 assessment.
