Project 10073 Record Card — Hendersonville, Kentucky, 17 Nov 60

On November 17, 1960, between 1300 and 1330 hours, witnesses in Hendersonville, Kentucky, observed an unidentified aerial object for approximately two minutes. The object was described as resembling a glider or a 'chicken hawk,' colored orange, dark brown, or black, and possessing wings similar to a U-2 aircraft. The witnesses reported that the object hovered at an altitude of 15,000 to 18,000 feet and emitted no sound. During the observation, the object dropped a fine, fiber-like material that took approximately 45 minutes to fall to the ground, covering a large area. The object subsequently departed at a 'tremendous speed.' The witnesses attempted to identify the object using binoculars but could not discern any insignia. Following the incident, a sample of the dropped material was collected and sent to the Aerospace Technical Intelligence Center (ATIC) for analysis. On November 23, 1960, the material was provided to a Mr. Naugle for examination. The subsequent analysis identified the substance as nylon thread. The official conclusion reached by the investigating agency was that the event was likely an air pollution control drop of some nature, although this could not be definitively verified with the State of Kentucky air pollution control authorities due to delays in the reporting process. The document includes a Project 10073 record card, internal correspondence from the Aerospace Technical Intelligence Center at Wright-Patterson Air Force Base, and notes regarding the material analysis.
