The source is a transcript of a conversation between individuals investigating a reported UFO sighting. The conversation focuses on the credibility of the witness, Andrew McMurtry, and the possibility that his sighting was a hallucination due to his previous time in a psychiatric ward. The transcript also includes testimonies from other witnesses, including Luke Primrose, who initially denied but eventually confirmed seeing the UFO. The investigation ultimately concludes that McMurtry's sighting is authentic, even though it is still officially classified as unknown.
