An object was seen in this locality on 30 June 1947. The hour was approximately 5:45 PM and we (my wife and I) were traveling west to the Plantation Golf Course, which is approximately five miles from Boise. On the way, I happened to spot something in the sky which seemed to be clinging to a huge cloud. It was half circled in shape and just as bright and silvery looking as a mirror caught in the rays of the sun. After a few minutes of traveling and looking the object disappeared. I would say it was about 10 miles distant, and from our location, approximately 3,000 feet in the air. Note: Witness states he has had "Aircraft Recognition" in the USAF about 4 times and is positive that the object sighted was not an airplane
