This document is a Project 10073 record card and associated U.S. Air Force Technical Information Sheet regarding a sighting that occurred on 27 July 1956 in Dayton, Ohio. A civilian witness reported observing a single, white, walnut-sized object for approximately 15 minutes. The witness described the object as standing still with jerky movements, traveling in an 'E and up' direction. The report includes a memo routing slip indicating that the sighting was received by a CWO named Hambleton. Following an investigation, the official conclusion reached was that the object was a balloon. The investigator noted that they checked with the Weather Service and determined that winds from 310-330 degrees would have carried a balloon from Old Orchard directly over the observer's location at a velocity of 10-15 knots. The report confirms that no photographs were taken and there was no radar contact. The witness provided details on the sky conditions, noting it was a clear night with a slight breeze and warm temperatures. The documentation includes the standard Air Force Technical Information Sheet, which the witness filled out to provide details on the object's appearance, motion, and their own location at the time of the sighting.
