Project 10073 Record Card and Technical Information Sheet — Dayton, Ohio, April 6, 1955

This document contains the official record and supporting technical information for a sighting reported on April 6, 1955, in Dayton, Ohio. The witness, a rocket test operator, reported observing a round, disc-shaped object while at the Wright Air Development Center (W.A.D.C.). The witness estimated the object to be approximately 100 feet in diameter and 20 feet thick at its thickest point, suggesting it was made of stainless steel or aluminum. According to the report, the object was observed for two to three minutes, moving westward in a straight line before making a 90-degree turn and climbing out of sight. The witness initially considered the possibility that the object was a balloon, but ultimately rejected this, noting that the flight characteristics and duration were more suggestive of an aircraft. The report includes a completed U.S. Air Force Technical Information Sheet, which provides detailed responses regarding the weather conditions, the witness's location, and the object's movement. The official conclusion recorded on the Project 10073 record card is that the object was an aircraft. The document also includes internal routing and coordination notes from the Air Technical Intelligence Center, dated April 8, 1955, indicating that the information was processed and filed by the Electronics Branch.
