Have you ever seen a UFO?

July 2 is the date of the supposed UFO crash in the 1947 Roswell incident. The "Roswell incident" was the July 1947 recovery of metallic and rubber debris from a military balloon by Roswell Army Air Field personnel, who issued a press release announcing possession of a "flying disc". The incident was forgotten until 1978, when retired lieutenant colonel Jesse Marcel was interviewed with ufologist Stanton Friedman. In that interview, Marcel revealed the "weather balloon" had been a cover story to divert public attention. In response, in 1994 the United States Air Force published a report concluding the crashed object was a top secret nuclear test surveillance balloon from Project Mogul. Do you think there was a UFO crash by aliens in Roswell in 1947?

High-ranking US government officials have "first-hand knowledge" of a secret Pentagon crash retrieval program for UFOs, Sen. Marco Rubio has claimed. Do you believe that the government has knowledge of UFOs and aliens existing that they have not shared?
