CASE FILE 016 · 2013

A federal surveillance camera followed a dark heat signature across Aguadilla. It seemed to race over rooftops, vanish into the Atlantic, return, and divide—until a later reconstruction moved the entire mystery back over land.

## AT A GLANCE

- **DATE:** April 25–26, 2013 (the public sources disagree on the local calendar date)
- **LOCATION:** Rafael Hernández Airport and the northwestern coast near Aguadilla, Puerto Rico
- **REPORT TYPE:** Airborne infrared recording and disputed transmedium interpretation
- **RECORD STATUS:** Resolved by AARO as probable sky lanterns; exact identity not certain

## The story

### A warm light approaches the old bomber field

Rafael Hernández Airport occupies the immense runway of the former Ramey Air Force Base on Puerto Rico’s northwestern shoulder. Late on an April night in 2013, a U.S. Customs and Border Protection De Havilland Canada Dash 8 was climbing and turning around that airfield. According to the later SCU account, supplied through an unnamed source rather than a published crew statement, the aviators first noticed a pinkish-red light approaching from the ocean. The tower could not identify it. As the visible glow faded near shore, the aircraft’s infrared operator acquired a small hot target.

### One night, two dates

The camera overlay bears the UTC date April 26. SCU converted the beginning of the recording to about 9:22 p.m. Atlantic Standard Time on April 25; AARO’s 2025 report instead calls it 9:22 p.m. local time on April 26. The official DVIDS catalog also uses April 26. No public acquisition log settles whether the disagreement is a time-zone conversion, a metadata convention, or a later dating error, so this archive preserves both dates rather than forcing an exact one.

### The little black shape in the box

For three minutes and fifty-four seconds, the public video holds a tiny black-hot signature near its tracking box while monochrome roads, trees, buildings, fields, and coastline slide underneath. It has no resolved wings, rotor, exhaust, or navigational lights. The target sharpens, blurs, flickers, and occasionally seems to disappear. Because the sensor magnifies a small patch of ground from a moving, turning aircraft, the sequence offers a powerful sensation of speed without giving an ordinary viewer a reliable sense of range.

### The moment Aguadilla became a transmedium legend

Near the end, the target crosses a water-toned background and repeatedly loses contrast. To viewers following its apparent path, it seems to descend into the Atlantic, continue beneath the surface without a splash, rise again, and then become two equal dark signatures. That sequence gave Aguadilla its special place in modern lore: not merely a light or a distant shape, but what appeared to be continuous government footage of an object passing from air to sea and duplicating itself.

### The 161-page extraordinary reading

A six-author Scientific Coalition for UAP Studies team broke the recording into frames, compared the sensor telemetry with maps and radar material, and published its report in 2015. Its preferred reconstruction put the object at roughly three to five feet long, generally moving around forty to one hundred twenty miles per hour, with a median near eighty. The team read brief disappearances over land as occlusion by trees, then extended that near-surface geometry toward the coast. It concluded that the target entered the water with little disturbance, emerged, enlarged, and divided into two objects.

### A pair of lanterns enters the argument

Retired Argentine Air Force commodore Rubén Lianza reached the opposite reading. He argued that the apparent dash across the landscape came from parallax, that the flickering thermal shape resembled two heart-shaped hot-air lanterns traveling together, and that east-northeasterly wind could carry them from the resort side of the airport. In his geometry the targets remained several nautical miles from the camera and over land even while water filled the background. The romantic detail—a paired wedding-lantern release—was vivid, but no wedding party or launch was independently documented.

### The Pentagon rebuilds the flight

AARO revisited the video with aircraft position, sensor azimuth, elevation, slant angle, and a Systems Toolkit reconstruction. Its model placed two objects near the airport’s northeastern side at about 656 feet, moving southwest in a straight line at approximately eight miles per hour. Recorded wind was about 9.8 miles per hour from the east-northeast. The Dash 8, meanwhile, climbed roughly 1,725 feet in an arc, and its range to the targets nearly tripled. In that reconstruction, motion parallax—not a low-level sprint—creates the spectacular ground speed.

### It never reached the ocean

The most consequential line in AARO’s solution is geographic: its projected sight lines keep the objects over land throughout the recording, ending above the airport’s central parking apron. The ocean appears behind them because the airborne camera looks across the coastline. Frames once interpreted as a target passing behind a utility pole were subjected to pixel analysis; AARO said the signatures did not cross behind it. Without that foreground anchor, the low altitude, high speed, and water entry no longer follow from the pixels.

### Two objects hiding as one

AARO identified separations at about 29.56, 40.76, and 47 seconds—well before the famous late split. It concluded that two small objects traveled close together from the beginning, repeatedly blending into one unresolved thermal blob. As the aircraft climbed, the viewing angle changed from shallow and side-on to steeper and more top-down, making their separation increasingly obvious. What looked like replication became a lesson in how sub-pixel targets can merge and part on a long-range infrared display.

### Why the targets vanish

The fading signatures also have an instrument-level explanation. AARO cites thermal crossover—the period after sunset when an object and its background can approach the same infrared temperature—along with increasing distance and scattered cloud near 3,000 feet. The recording began within two hours of sunset, the targets were smaller than three feet in AARO’s estimate, and the camera-to-target range grew substantially. Under those conditions a warm object may flicker out against land or water without entering either one.

### From leaked mystery to official case study

For years the clip circulated through investigators and internet archives without an official public release, accumulating the reputation of a government video too strange to explain. DVIDS finally published the original sequence in November 2024, and AARO issued its resolution and animated reconstruction in March 2025. Aguadilla’s cultural afterlife now contains both stories at once: the celebrated transmedium passage built from SCU’s geometry, and the official two-lantern solution built from a different reconstruction of the same black-and-white frames.

## The evidence

### What the recording securely establishes

The 3:54 sequence is authentic U.S. Customs and Border Protection infrared footage from a Dash 8 operating near Rafael Hernández Airport. Embedded telemetry records the aircraft and sensor state, and the landscape can be compared with the airport. The camera followed one or more unresolved thermal targets. Authentic provenance does not, by itself, fix their distance, speed, altitude, identity, or relationship to the water behind them.

### The missing firsthand record

The public file does not include named crew interviews, a contemporaneous incident report, control-tower audio, a preserved tower log, or an original visual-observation statement. The pinkish-red light, tower confirmation, delayed commercial departure, and crew reaction enter the story through SCU’s unnamed source. Those details may be accurate, but they cannot be checked with the same confidence as the pixels and telemetry in the released video.

### Two reconstructions, one decisive unknown

SCU’s anomalous trajectory and AARO’s windborne trajectory depend on where the targets are placed along the camera’s changing line of sight. SCU used apparent occlusion by foreground objects to argue for a low, fast track. AARO rejected the key pole occlusion and integrated the aircraft and sensor angles into a farther, slower path. The public video contains no independent laser range to the targets, so geometry—not a direct range measurement—carries the dispute.

### The official resolution and its limit

AARO assesses with high confidence that no anomalous speed or transmedium behavior occurred, and with moderate confidence that the targets were two sky lanterns. It cites their sub-meter size, wind-matched path, variable heat signature, and information from local hospitality vendors that lantern releases were common. Moderate confidence matters: AARO resolved the extraordinary performance, but it did not produce a launch record, owner, recovered lantern, or categorical identification.

### Classification

This file is classified as an identified-performance case with an uncertain exact object. The government video is genuine; the apparent rush across the airport, split, and ocean entry are not supported by AARO’s reconstructed flight path. Two windborne lanterns currently provide the strongest developed explanation. The case remains valuable because it preserves the full illusion: a tiny warm target, a moving sensor, changing zoom, fading contrast, and a coastline can manufacture a sequence that looks like impossible machinery without a single fabricated frame.
