A NASA imaging specialist that analyzed and wrote reports about the STS-48 UFO footage.
Lan Fleming worked for NASA as an imaging specialist and examined the STS-48 video recorded through NASA's Space Shuttle Discovery on September 15, 1991. He noted that several of the objects appear to be stars or space debris moved by the shuttle's thruster. However, based on some of the motions and turns that the objects make, Fleming does not believe that they all fit into these categories. He concluded, "These trajectories are inconsistent with those of debris propelled either by a shuttle thruster or by sublimation. They are, however, consistent with the flight paths of large self-propelled objects moving around the curvature of the Earth."
