Newly declassified video and audio show U.S. Navy pilots apparently encountering a UFO — with no wings and no tail — as they flew their Boeing F/A-18 Super Hornet fighter jet along the East Coast in 2015.

“What … is that thing?” one pilot can be heard saying in the video.

“Oh my gosh, dude! Look at that flying!” another exclaims.

According to a report on ABCNews.com, the 35-second footage, captured by an infrared camera aboard an F/A-18 fighter jet traveling at 25,000 feet, was released Friday by To the Stars Academy of Arts and Science (TTSA), a private scientific research and media group. It is led by Hal Puthoff, a NASA and U.S. Department of Defense adviser, and James Semivan, a former Central Intelligence Agency official.

The Department of Defense declined to comment on the video.

The new video comes soon after two other declassified videos of supposed UFO sightings by U.S. Navy pilots were published by The New York Times in December.

In one of those encounters, pilots David Fravor and Commander Jim Slaight, who were flying off the Southern California coast in F/A-18F Super Hornets, described seeing an oval-shaped object hovering above the sea.
