Maryland UFO|UAP & Alien Sightings Archive

Maryland’s seven-case UAP archive carries an unusual concentration of professional and institutional witnesses — an aeronautical engineer, a Lockheed engineer, military-adjacent suburban observers near the Washington DC corridor — and its anchor case produces one of the most thoroughly documented vehicle-interference and physiological-effects encounters in the mid-Atlantic record. On October 26, 1958, at approximately 10:30 PM, two men driving near Loch Raven Dam in Baltimore County encountered a large egg-shaped object hovering silently over the dam’s bridge. Their car engine died and the vehicle stalled approximately 75 to 80 feet from the object. The radio also failed. One of the men got out to investigate; the object emitted a brilliant white flash and an intense heat wave that knocked him back into the car. Both men drove immediately to Maryland’s Bon Secours Hospital where one was treated for symptoms consistent with radiation burns or severe UV exposure — the skin of his face and arms reddened and painful. The burns lasted approximately two weeks. The case was filed with the Air Force, investigated by NICAP, and documented in Project Blue Book as one of the few cases with simultaneous vehicle interference, EM effects, and physiological injury. A follow-up investigation found that another witness had independently seen the same object near the dam that night from approximately eleven miles away. Maryland’s proximity to Washington DC — the NSA at Fort Meade, Andrews Air Force Base, the Pentagon — gives its UAP cases a strategic context that amplifies the institutional observer significance, particularly the 2005 Lockheed engineer’s detailed report of a slow-moving silent black triangle at low altitude, filed formally despite obvious professional risk.

Executive Summary

Loch Raven and the Radiation Pattern — Maryland’s Physical Evidence Record

Maryland’s UAP archive is defined by its one physically evidenced CE-II. The Loch Raven Dam case carries the complete trifecta of UAP physical evidence: vehicle interference (engine and radio failure), electromagnetic effect (heat wave producing knock-back force), and physiological injury (radiation-burn symptoms treated at a named hospital). The independent second witness from eleven miles away removes the two-man car-stall isolation and provides corroboration from a completely separate vantage point. The medical treatment at Bon Secours Hospital provides a documented institutional record of the physical aftermath. No conventional explanation has been proposed for the simultaneous engine failure, radio failure, heat wave, radiation symptoms, and independent observation at a distance that occurred at Loch Raven Dam on October 26, 1958. The 2005 Lockheed engineer triangle adds professional technical witness quality to the modern record — a Lockheed engineer has specific aircraft identification training and a specific professional incentive not to report anomalous aerial observations, making the formal report filing the analytically significant event. Maryland’s seven cases are concentrated in the Baltimore-Washington corridor and carry a consistent institutional observer character across seven decades.
