Monroe, OhioAugust 1961

On August 30, 1961, a fourteen-year-old in Monroe, Ohio reported seeing an unusual object in the night sky. The witness had just watched a movie about flying saucers and believed the object might be related to what he had seen on screen. The object appeared in the northeast and traveled southwest, moving, according to the witness, as fast as the Echo satellite. The witness reported that the object started out white and changed color to amber as it traveled. The sighting lasted two minutes and twenty-six seconds.

The same evening, residents of the Dayton, Ohio area (about fifty miles south) also reported seeing a bright light in the sky around 9 p.m. local time. According to newspaper accounts included in the file, at least a dozen people witnessed a flickering red light that first appeared in the northeast and headed southwest at a steep angle above the horizon. The light suddenly exploded into a brilliant white glow and then vanished. The object was visible for several minutes. The Cincinnati Weather Bureau, the Greater Cincinnati Airport control tower, and a local Moonwatch team (volunteers who tracked satellites) all said they could not identify the object. They ruled out airplanes, among other possibilities.

The Air Force investigated both sightings. In the Monroe case, the file notes that the witness's description of speed could match a conventional or jet aircraft, and no connection was established between the Monroe sighting and the Dayton sighting, so the case was evaluated as "probably aircraft." In the Dayton case, investigators concluded the most logical explanation was a high-flying jet aircraft. They noted that jet aircraft have white lights on their undersides that are only visible at high altitudes, and that wind direction and altitude could explain the absence of sound. The changing angle of observation and increasing distance, they suggested, could make the light appear to snap out suddenly. That case was also evaluated as "probably aircraft."
