Exercise Mainbrace (1952)
Exercise Mainbrace was a NATO-sponsored military exercise that took place from September 13 to 20, 1952, in the North Atlantic. The participating countries included the United Kingdom, the United States, and Denmark.

The reports of UFO sightings during Exercise Mainbrace came from multiple sources. British, American, and Danish officers claimed to have observed peculiar aerial objects that they could not identify. The descriptions included a blue-glowing triangle, a silver sphere, and a silvery circular object. These sightings raised questions about the nature and origin of these unidentified objects.
- Lieutenant Colonel Charles Halt (US Air Force): Lt. Col. Halt, who later became well-known for his involvement in the Rendlesham Forest incident in 1980, reportedly witnessed UFO activity during Exercise Mainbrace. According to his statements, he observed a strange object emitting a red light in the sky and witnessed it descend into the forest. Halt’s account gained attention and has been referenced in various UFO investigations and documentaries.

Ruppelt, the head of the U.S. Air Force’s Project Blue Book, acknowledged the UFO sightings during Exercise Mainbrace in his book “The Report on Unidentified Flying Objects.” He mentioned that military personnel reported seeing unidentified objects and that the sightings were taken seriously by the authorities.
