ARTESIA, NEW MEXICOJanuary 1952
Summary
On January 16, 1951, an aeronautical engineer working for General Mills reported seeing two unusual objects near a research balloon over Artesia, New Mexico. The engineer was tracking the balloon, which floated at about 110,000 feet altitude and measured roughly 110 feet across. When he first spotted the objects from the ground in front of a hotel, one of them appeared to move upward toward the balloon's position. He later observed the two objects together in the sky, moving in a straight line and covering about 30 degrees of direction in roughly three seconds before vanishing. The observer described them as opaque, off-white in color, and similar in size to the balloon he was tracking. He held an aeronautical engineering degree, had piloted aircraft for the Air Force for three years, and had been doing balloon research for over a year.
Additional witnesses at the Artesia Airport also saw the incident. A manager of the airport and several civilian pilots watched as two objects appeared to circle the balloon or moved near it in formation, traveling side by side. The observers stated the objects were dull gray or dull white, larger than the balloon, and moved with sudden acceleration before flying off rapidly to the northeast. All witnesses insisted the objects were not reflections or conventional aircraft, and they observed clear skies that morning with no clouds obscuring visibility. The observers were described as reliable and experienced.
The Air Force investigation faced a significant delay. The sighting occurred on January 16, 1951, but no report reached the Air Force until April 1952, more than a year later. The lead investigator noted that due to this time gap, no further investigation was pursued. The file was then closed by the Office of Special Investigations. The case has been reproduced below as held by the National Archives in 15 pages.
