Project 10073 Record Card: Sighting in Kaiapoi, New Zealand, Winter 1951

This document file contains a Project 10073 record card and associated correspondence regarding a sighting in Kaiapoi, New Zealand, during the winter of 1951. A civilian witness reported observing a large cloud formation, approximately 500 yards long and wide, from which a smaller piece detached and moved with a whirlwind-like appearance before traveling north and then east. The witness, who was a single man living alone and working in an engineering factory, submitted photographs and negatives of the event to the United States Air Force in 1954. He explicitly stated that his intention was not to report 'flying saucers' but to share an unusual atmospheric observation. The Air Technical Intelligence Center (ATIC) evaluated the photographs and concluded that the object was a lenticular altocumulus cloud, a formation often resulting from the atmospheric conditions described by the witness. The correspondence shows a professional exchange where the ATIC requested the negatives for further analysis and subsequently returned them to the witness. The file includes internal routing slips and letters from the witness to the Commanding Officer of the American Army Air Force, as well as responses from the ATIC. The witness also mentioned a separate, unrelated report from aerial top-dressing pilots in New Plymouth, New Zealand, who had observed a formation of circular spheres. The final assessment by the Air Force remained that the primary sighting was a natural atmospheric phenomenon.
