Project 10073 Record: UAP Sighting Reports, September 1966

This document contains a collection of U.S. Air Force Project Blue Book records regarding unidentified aerial phenomena reported on September 17, 1966. The records include multiple FTD Form 164 questionnaires completed by civilian witnesses in various locations, including Dayton and Centerville, Ohio, and Salt Lake City, Utah. The reports describe a bright, yellow-to-orange object with a flaming tail, often compared to a meteor or an explosion in mid-air. Witnesses estimated speeds ranging from 800 to 900 mph and described the object's movement as a straight line. The Air Force, under the direction of Major Hector Quintanilla, Jr., determined that the information provided in these initial reports was insufficient for a formal evaluation. Consequently, the project issued correspondence to the witnesses requesting that they complete and return the provided FTD Form 164 to facilitate further investigation. A summary note indicates that two distinct aerial phenomena were reported: one seen widely across the Northeast U.S. and a second reported indirectly with a sighting time of 0415Z on September 18, 1966. The only available data for the second event suggested the object appeared greenish.
