The Aurora crash differs from the Roswell crash in that original documentation was not tampered with by the military nor were the still living eye witnesses debriefed, or told to keep quiet by the military. Hewes found that many residents, wanted very little if anything to do with the story of the crash, but 3 or more people who were alive at the time were willing to talk to investigators. Robbie Hansen although not a direct witness considered the incident to be untrue simply because her father laughed at the story and thought it was a hoax. Two other witnesses provided first hand accounts of the sighting, contradicting Robbie Hansen. Mary Evans, who was 15 at the time, recalled that something did crash; her parents went to see the crash, but would not let her view the scene.
