Tremonton film (Utah, 2 July 1952)

Unproven Handling What these labels mean →

Navy photographer Delbert Newhouse filmed about a dozen bright objects moving in formation. Navy analysts favored 'unidentified light sources'; later reviews considered balloons, birds, insects and mirage; a 1956 study was inconclusive; an Air Force memo settled on seagulls. Release 06 published the full Blue Book file and his personnel record.
