Loch Raven Dam UFO Incident
A car and its occupants experienced electromagnetic effects and physiological symptoms during a close encounter with an egg-shaped craft over Loch Raven Reservoir in Maryland.
The Encounter
On the night of October 26, 1958, around midnight, Alvin Cohen (age 24) and Phillip Small (age 27) were driving near Loch Raven Reservoir in the Hunt Valley area of Towson, Maryland, when they observed a large, luminous, egg-shaped object hovering approximately 100 to 150 feet above a bridge near the reservoir. The craft appeared iridescent and flat, with estimates suggesting it was roughly 100 feet in length. Intrigued by the phenomenon, the two men drove closer to investigate.
The Physical Effects
As the witnesses approached the object, their automobile suffered a complete electrical failure—the engine died, the headlights extinguished, and the ignition became unresponsive, rendering the vehicle inert. The men exited and hid behind their car, watching the craft above them. Moments later, a brilliant flash of light accompanied by noise and an intense wave of heat emanated from the object, causing the witnesses to shield themselves. The craft then rose vertically into the sky at high speed and disappeared.
The physiological effects on the men were immediate and alarming. Both Cohen and Small developed sunburn-like symptoms on their exposed skin—primarily their faces—and experienced concern about possible radioactive contamination. They drove to St. Joseph Hospital on East Caroline Street in Baltimore for medical evaluation. Although hospital staff examined them, they did not require treatment beyond observation. The case was notable for its documented physical manifestations: the vehicle's electrical system failure and the burn-like marks on the witnesses, which were corroborated by hospital records.
Corroborating Witnesses and Official Investigation
The incident was not isolated to Cohen and Small alone. A 16-year-old boy and two employees working at a nearby lakefront restaurant also reported observing similar glowing objects in the same area and timeframe, lending additional credibility to the sighting. The case was formally investigated by Project Blue Book, the U.S. Air Force's official UFO investigation program, and assigned case number BBU 6148. Air Force investigators concluded that although the incident did not represent a national security threat, they were unable to provide any definitive explanation for the event. The case remains officially classified as "unidentified"—no known aircraft, balloon, meteor, or natural phenomenon could satisfactorily explain the sighting and its associated physical effects.
Legacy and Rediscovery
Despite occurring during the height of American UFO interest in the 1950s, the Loch Raven incident remained relatively obscure compared to more famous cases from the era. In recent decades, researchers and local Maryland historians have given renewed attention to this case, particularly following a 2018 retrospective in the Baltimore Sun marking sixty years since the encounter. The case exemplifies the category of well-documented close encounters with measurable physical effects—a subset of UFO incidents that presents particular challenges to skeptical explanation.
