University of Pennsylvania historian Kathryn Dorsch sees parallels with Cold War era interest in UFOs and says that alien-piloted UFOs are not a likely explanation. According to Dorsch, "God love the US Air Force, but answering fundamental epistemological questions is not super high on their to-do list. This is why the military has always struggled with this UFO question. They want to know if this thing is a threat, and if it's not, great."
