For the third time in three months, a declassified Defense Department video shows U.S. Navy F-18 fighters seemingly encountering UFOs.

"Oh my gosh, dude,' said one pilot in the video of their F/A-18 Super Hornet military jet's 2015 encounter with the unusual object along the East Coast.

The oval-shaped aircraft zipped with befuddling speed.

"Wow! What is that, man?' said another. "Look at that flying!'

Mulder and Scully would approve.
