PROJECT 10073 RECORD CARD — Ottawa, Canada, 9 May 60

This document contains a Project 10073 record card and associated correspondence regarding an unidentified aerial phenomenon reported on May 9, 1960, in Ottawa, Canada. A witness, identified as a civilian and member of the Canadian Air Force, reported observing a light in the sky at approximately 2:15 A.M. while driving near the Ottawa River. The witness initially believed the light to be an aircraft approaching Rockliffe airport. However, the object exhibited unusual behavior, including sudden spurts to the side and a zig-zag course. When the object passed behind a cloud, it appeared to develop a 'halo' effect. The witness reported that there was no sound. Following the sighting, the witness contacted the local control tower and airlines, confirming that no aircraft were in the vicinity at that time. The witness, who expressed skepticism regarding such reports, provided a detailed letter and a hand-drawn diagram of the object's path to the authorities. The official Air Force evaluation, signed by Lt. Col. Lawrence J. Tacker, noted that the report contained insufficient information to reach a valid conclusion. While the document suggests the possibility of light refraction caused by fog and an inversion layer, it acknowledges that the lack of aircraft in the area complicates this explanation. The witness was requested to complete a standard UFO questionnaire to facilitate further investigation, though the record indicates that the request for additional information was not answered. The file includes the original record card, the witness's letter, a memorandum regarding the forwarding of the questionnaire, and the witness's hand-drawn map of the flight path.
