The Tremonton film

Navy Chief Warrant Officer Delbert Newhouse, an expert aerial photographer with over 1,000 hours of experience, pulled his car over and filmed 12 to 14 bright objects milling in the sky. Blue Book rated him honest and reliable. Navy photo analysts concluded the objects were not birds, balloons or known aircraft. A year later the CIA's Robertson Panel dismissed them as seagulls. war.gov has now released the film itself, the Blue Book file, the balloon tests, and Newhouse's own service record.
