This local source record summarizes "1947: The Year of the Flying Saucer", published or preserved by Smithsonian National Air and Space Museum.
The museum history explains how Arnold's 24 June 1947 report helped popularize the phrase flying saucer and shaped the first major postwar wave of reports.
This is historical context rather than a primary witness transcript, and the origin of a popular term does not validate the reported object's nature.
