Navy pilots were often unsettled by the sightings. In one encounter, strange objects — one of them like a spinning top moving against the wind — appeared almost daily from the summer of 2014 to March 2015, high in the skies over the East Coast. Navy pilots reported to their superiors that the objects had no visible engine or infrared exhaust plumes, but that they could reach 30,000 feet and hypersonic speeds.Since UFOs are defined as being something nobody can identify or explain then it does not make sense to assume certain things about them which may not be true at all.
Lt. Ryan Graves, an F/A-18 Super Hornet pilot who was with the Navy for 10 years, told The New York Times in an interview, “These things would be out there all day.” With the speeds he and other pilots observed, he said, “12 hours in the air is 11 hours longer than we’d expect.”

A new report concedes that much about the observed phenomena remains difficult to explain, including their acceleration, as well as ability to change direction and submerge.
