 According to its author/s the majority of analyzed UFO sightings can be explained by the misidentification of common objects such as aircraft and balloons, while the remaining unexplainable reports were most likely the result of a supernormal meteorological phenomena not fully understood by modern science.This phenomenon is referred to in the report as "Buoyant Plasma Formation," akin to Ball Lightning, and is hypothesized to produce an unexplained energy field which creates the appearance of a Black Triangle by refracting light.The electromagnetic fields generated by plasma phenomena are also hypothesized to explain reports of close encounters due to inducing perceptual alterations or hallucinations in those affected.
