Not only have the sightings been happening worldwide, but Christopher Mellon, a former deputy assistant secretary of defense for intelligence, says the unidentified flying objects pose a "vital national security threat."

According to a report by the New York Post, Mellon says that the U.S. Navy pilots who recently reported seeing UFOs on a near-daily basis in 2014 and 2015 have legitimate concerns about their time on Earth. In numerous interviews, Navy pilots have revealed that they have seen UFOs moving at hypersonic speeds, performing acts "beyond the physical limits of a human crew," and emitting "no visible engine or infrared exhaust plumes."

The speeds that were being reported by Navy pilots (about 5,000 miles per hour, according to Mellon) were only sustainable for about an hour by an aircraft in the air, and these objects would be flying around all day long, the pilots said. "Pilots observing these craft are absolutely mystified and that comes through clearly in their public statements," Mellon continued.

"They're deeply frustrated and that is the core of our show," Mellon said in an interview with "Fox & Friends" on Fox News Wednesday, where he pushed his forthcoming History Channel series titled "Unidentified," which looks into the UFO phenomenon. Mellon is also concerned about UFO sightings and he's begging the government to take action. (We know what the means: war.)
