UFO sighted near Madrid in 1959

Summary

In August 1959, near Madrid, Spain, two air force officers observed a bright yellow-green object moving at high speed. The object, described as the size of a baseball and resembling a balled fist, was seen for about 4 seconds. Although the possibility of it being a balloon or an astronomical phenomenon was considered, the witnesses agreed it did not match either. The report notes that the object moved in a straight line without maneuvers and emitted pulses for one second without exploding, which surprised the observers.

The report includes weather data and testimonies from other military personnel in the area, though no additional confirmed observations were made. Despite the lack of physical evidence, the officers deemed the sighting noteworthy due to its clarity and consistent descriptions. This case is part of a series of reports from the time showing how unexplained aerial phenomena were treated with care, though without reaching definitive conclusions.
