PROJECT 10073 RECORD CARD - 10 MARCH 1957 - JACKSONVILLE, FLORIDA

This document consists of a Project 10073 record card and associated teletype communications regarding an unidentified aerial phenomenon reported on March 10, 1957, in Jacksonville, Florida. At approximately 1600 local time, a housewife and her children observed a single, white, saucer-shaped object in a vertical position, described as being the size of a silver dollar. The object was reported to be traveling at a 'terrific speed' and heading south from Jacksonville toward Miami. The observation lasted approximately ten seconds. The report notes that the object was seen overhead and appeared to disappear vertically. Military authorities, specifically the 660th ACWRON at MacDill AFB, investigated the report. The official conclusion reached by the evaluating agency, the Air Technical Intelligence Center at Wright-Patterson AFB, was that the sighting was likely an aircraft. The documentation includes teletype messages sent between various military commands, including the Air Defense Command at Ent AFB and the 35th Air Division at Dobbins AFB, confirming the details of the report and the lack of radar contact or other corroborating evidence. The comments section of the record card highlights a potential error in the reported duration and notes that the children involved had called their parents to witness the phenomenon. The 660th ACWRON Operations Officer provided no further comment on the incident.
