On 13–14 August 1956, RAF and USAF personnel at RAF Lakenheath and Bentwaters tracked unidentified objects on multiple radars and saw them visually over two nights. The object identity was never settled.
Lakenheath matters because it is a multi-radar, multi-witness military case that predates Rendlesham by decades — a test of treating radar-visual correlation without overstating its meaning.
Over two consecutive nights, objects were tracked on multiple ground radar systems. RAF and USAF personnel reported the returns.
Documented
The radar returns and the two-night sequence are documented.
Personnel reported seeing objects corresponding to the radar returns. This radar-visual correlation is the core of the case.
Documented
The visual reports are documented.
Project Blue Book and the Condon Committee treated the case. A competing reading attributes the returns to anomalous radar propagation. The object identity remains disputed.
Debated
Anomalous propagation vs real targets is contested.
Radar-visual correlation is significant, but it does not by itself establish an extraordinary craft. The object identity was never settled.
Unverified
Any extraterrestrial origin is unverified.
These sources do different jobs: Blue Book, the National Archives and Condon are the official records, and Wikipedia is the reference. None establishes the object identity.
