Project 10073 Records — Indianapolis, Indiana, May 1966

This document contains records from Project 10073, specifically regarding two separate unidentified aerial phenomena sightings reported in Indianapolis, Indiana, in May 1966. The first incident occurred on 4 May 1966, involving a single witness who reported a football-shaped, orange object traveling southwest. The witness described the object as having a low rumbling sound, flickering, and changing brightness before disappearing behind trees. The second incident occurred on 18 May 1966, near Weir Cook Airport, involving a witness who described an object resembling a blimp that moved in a zig-zag pattern and was observed for approximately 30 minutes. In both instances, the U.S. Air Force, through the Project Blue Book office at Wright-Patterson Air Force Base, sent FTD Form 164 to the witnesses to gather more detailed information. However, the records indicate that in both cases, the forms were not returned within the 30-day window. Consequently, Major Hector Quintanilla, Jr., Chief of Project Blue Book, concluded that there was insufficient data for a formal evaluation of either sighting. The file includes correspondence from the Air Force to the witnesses, internal memo routing slips from duty officers noting difficulties in reaching witnesses, and the technical information questionnaires completed by the witnesses.
