Project 10073 Record Card — Tacoma, Washington, 1 August 1958

This document comprises a collection of records and correspondence regarding an Unidentified Aerial Phenomena (UAP) sighting that occurred on August 1, 1958, in Tacoma, Washington. The primary record is a Project 10073 card, which documents a 45-minute observation of a white, very bright object described as having an 'ice-cream cone' shape on its underside. The sighting involved multiple witnesses, including military personnel from the US Coast Guard, and was tracked via visual and ground radar. Reports regarding the object's flight path were conflicting, with some witnesses reporting movement from North to South, others from West to East, and some from Northeast to North-Northeast. The object was also reported as 'grapefruit-like' in appearance. Following the incident, the Air Technical Intelligence Center (ATIC) requested tracking data from the 1110th Balloon Activities Group to determine if the object could be identified as an upper-atmosphere balloon. The 1110th Balloon Activities Group responded that they had no record of any balloon or related activities in the Tacoma area on the date in question. Consequently, the official conclusion remained that while the object possessed characteristics of a balloon, the inconsistent data provided by witnesses made a definitive conclusion impossible. The file includes internal military communications, including a joint message form, detailing the request for information and the subsequent negative response from the balloon activities group, as well as handwritten notes from investigators expressing frustration with the long duration of the sighting and the lack of conclusive data.
