Shortly after leaving Boise, the crew of a United Air Lines flight reported five flat-bottomed objects silhouetted against the sunset and followed them for about 45 miles. Ten days after Kenneth Arnold's report, it was one of the first airline crew sightings and is cited in a 1952 CIA briefing.
A Fourth Air Force intelligence memorandum dated July 16, 1947 recorded a July 12 interview with Kenneth Arnold in Boise. The interviewer judged that Arnold saw what he described and found his distances consistent with aeronautical charts; copies went to the FBI.
