Need to Know: UFOs, the Military and Intelligence

Need to Know examines UFO reports through the lens of military and intelligence activity, assembling cases from the 1920s onwards. Timothy Good draws on declassified government documents, news reports, eyewitness affidavits and testimony attributed to military and airline pilots, naval personnel and former insiders.

The book considers alleged official secrecy alongside reports of encounters involving large unidentified craft, aircraft accidents, missing military aircraft and more recent near-misses. Its international scope brings together claims from different periods and countries, while presenting the evidence as part of a long-running dispute over what governments and armed forces have known about UFOs. The subject is treated through reported events, documentary material and contested testimony rather than settled proof.
