Project 10073 Record Card and Teletype Report — 16 April 1955

This document consists of a Project 10073 Record Card and an associated teletype message regarding a UFO sighting that occurred on April 16, 1955, in Los Angeles, California. The witness, a 17-year-old student, observed a single, round, white object at an estimated altitude of 5,000 feet. The observation lasted for one minute and thirty seconds, during which the object was seen moving straight up until it went out of sight. The weather conditions at the time were described as slightly windy and hazy. The report explicitly notes that there was no radar contact and no photographs were taken. The official conclusion reached by the Air Technical Intelligence Center (ATIC) was that the object was a weather balloon (WX balloon). The teletype, sent by the 669th ACW Squadron, provides additional technical details, including an angle of elevation of 45 degrees and an azimuth of 132 degrees. The document serves as a standard record of a sighting investigation conducted under the auspices of the Air Force's intelligence gathering efforts during the mid-1950s.
