Project 10073 Record — Yosemite National Park, California, 27 July 1965

This document contains a sighting report and subsequent correspondence regarding an unidentified aerial phenomenon observed in Yosemite National Park, California, on July 27, 1965. The witness, a civilian, reported observing five objects—four white lights and one red light—moving from west to east at 21:15. The witness described the lights as being of the first magnitude or brighter, similar to stars, and noted that they moved at a constant speed without producing any noise, despite being close enough that an airplane would have been audible. The observation lasted approximately 15 seconds. The witness provided a detailed questionnaire, noting that the objects appeared as a group of bright stars moving quickly across the horizon. The witness also compared the objects' path to the 'Firefall' event at Yosemite, noting that the objects appeared to move from the direction of the Firefall. Major Hector Quintanilla, Jr., Chief of Project Blue Book, responded to the witness on August 25, 1965, stating that the initial information was insufficient for evaluation and requesting that the witness complete an FTD Form 164 to provide specific data on the angular separation of the lights. An internal note on the record indicates that further contact with the witness was not deemed advisable at the time, as it might suggest the report held more importance than its actual value warranted. The official conclusion remained tentative, suggesting the objects were likely aircraft, pending further data on the angular separation of the lights.
