(CBS NEWS) -- Some U.S. Navy pilots reported seeing unidentified flying objects while training over the East Coast in 2014 and 2015 in interviews with The New York Times. According to The Times, multiple Navy pilots spotted "strange objects" with "no visible engine" reaching 30,000 feet and going hypersonic speeds.
The Times report includes a minute-long video of two encounters Navy pilots allegedly had with unexplained aerial phenomena. In the videos, which include visual radar and voice recordings, pilots cannot distinguish what is seen on their radar screens. At one point one of the pilots says in amazement, "Look at that thing. It's rotating."
"These things would be out there all day," Lt. Ryan Graves, an F/A-18 Super Hornet pilot and 10-year Navy veteran, told The Times. "Keeping an aircraft in the air requires a significant amount of energy. With the speeds we observed, 12 hours in the air is 11 hours longer than we'd expect."
