This excerpt is a recording of a 1950s-era United States Air Force investigation into unidentified flying object sightings at a military academy in Iowa. The episode focuses on the investigation of several cadets who claim to have witnessed a strange, web-like substance that covered the area and turned their hands green. The investigators eventually determine that the "angel hair" is a new material being tested by the military for radar disruption. This investigation serves as a window into the early days of UFO research and the attempts to explain the phenomenon through scientific means.
