Project 10073 Record Card — Port Columbus, Ohio, 24 April 1957

This document comprises a Project 10073 record card and associated U.S. Air Force Technical Information Sheets detailing a sighting reported on April 24, 1957, in the vicinity of Port Columbus and Dayton, Ohio. The primary witness, a 29-year-old housewife, reported observing a single object for approximately one hour between 21:00 and 22:00 local time. She described the object as appearing like a bright star, comparable in size to a baseball or flashlight, emitting a white light with no other discernible features. According to the witness, the object hovered and exhibited erratic movements, shifting north, east, and west before eventually moving straight west and disappearing without dropping below the horizon. The witness noted that the object's movements were observed in relation to a WHIO transmitter tower. Her husband was briefly alerted to the object but did not maintain interest. The official conclusion recorded on the project card is 'Balloon observation.' Supporting documentation includes weather data from the Military Flight Service and the U.S. Weather station at Van Dalia, which noted a balloon launch at 21:15 that headed south or southwest. The weather conditions at the time were described as clear with a slight breeze and cool temperatures. The witness confirmed she had no special training and that this was the first time she had seen such an object, stating she did not know what it was.
