The Black Vault (USAF records) · 62 pages · text by OCR

This US Air Force Project Blue Book case file on Kenneth Arnold's sighting of nine objects near Mount Rainier, Washington, on 24 June 1947 was released through The Black Vault. It contains the Project 10073 record card, which concludes the objects were a mirage, plus Arnold's telegram, questionnaire data and interview notes. It also includes J. Allen Hynek's analysis arguing the objects were closer and slower than Arnold estimated. Other items are David Johnson's sworn statement on a Boise sighting, a Tacoma investigation telegram and news clippings.
