Experts asked legislators to recognize UAP, guarantee airspace security, and allow UAP to be studied. They presented to alleged alien corpses and videos of Mexican pilot’s encounters with fast-moving flying objects during flight. Disagreement about the efficacy and validity of the purported alien corpses.
