Ministry of Defence assessment concluded the reported lights posed no threat to national security and were likely explained by the nearby Orfordness Lighthouse beacon and local civilian aircraft activity. No corroborating radar evidence was found to support claims of unknown aircraft in the area. The case was closed with no further investigation deemed necessary per standard MOD policy regarding UFO reports.

The Halt Memo
Dated January 13, 1981 and titled "Unexplained Lights," this single-page memorandum from Deputy Base Commander Lieutenant Colonel Charles I. Halt to the UK Ministry of Defence remains the primary official document of the incident. Released under the U.S. Freedom of Information Act in 1983, the unclassified memo describes a "glowing object, metallic in appearance" observed over multiple nights, triangular ground depressions, elevated radiation readings, and objects that "beamed down a stream of light from time to time." The two-week delay between events and report may account for date discrepancies. The original document is preserved at The National Archives in Kew, London.

Investigation Verdict
This case stands apart due to multiple trained military observers, contemporaneous documentation, and physical trace evidence. While skeptics point to the lighthouse theory, it fails to explain the recorded radiation readings, ground impressions, and close-range observations by experienced personnel. The witnesses' consistency over 40+ years, combined with official documentation, suggests something genuinely anomalous occurred. However, without conclusive physical evidence, the exact nature remains unexplained.
