Project 10073 Record — Appleton, Wisconsin, 4 February 1968

This document contains a Project Blue Book sighting report (Project 10073) regarding an unidentified aerial phenomenon observed in Appleton, Wisconsin, on February 4, 1968. The witness, a 13-year-old, reported observing a bright red, pulsating light in the southern sky. The witness initially believed the object was the planet Saturn, but noted that it hovered momentarily before moving in a northeasterly direction. The witness described the object as having a humming sound and estimated its speed at 30 mph. The observation lasted approximately four minutes. The Air Force attempted to follow up with the witness by sending an AF Form 117 questionnaire, but the correspondence was returned as 'address unknown.' A second attempt to contact a witness also failed. The official conclusion recorded by the Foreign Technology Division was 'Probable (AIRCRAFT),' noting that there was no evidence to suggest the object could not have been an aircraft. The file includes the original correspondence from the Foreign Technology Division, signed by Major Hector Quintanilla Jr. and Colonel James C. Manatt, as well as the blank and partially completed questionnaires.
