Project 10073 Record — Yorba Linda, California, 28 August 1968

This document contains a record from Project 10073 regarding a UFO sighting reported in Yorba Linda, California, on 28 August 1968. The witness, whose name is illegible in the provided documentation, reported observing a 'white ball' object flying near an airplane at approximately 10:13 pm. According to the witness's account, the object approached the airplane from the left at a high speed, appearing as if it would collide with the aircraft. The object then reportedly crossed over the wings to the right side and moved to the center of the wings before disappearing. The witness emphasized the extreme speed of the object, stating that it moved faster than a jet. The Air Force, specifically the Foreign Technology Division (AFSC) at Wright-Patterson Air Force Base, reviewed the report. On 18 September 1968, Lt. Colonel Hector Quintanilla, Jr., Chief of the Aerial Phenomena Office, sent a letter to the witness stating that the information provided was insufficient for a scientific investigation. The Air Force requested that the witness complete an AF Form 117 and return it in an enclosed self-addressed envelope. As of 17 October 1968, the form had not been returned, leading to the final conclusion of 'insufficient data for evaluation' in the project record.
