“Well, we’ve got a real-world vector for you,” the radio operator said, according to Commander Fravor. For two weeks, the operator said, the Princeton had been tracking mysterious aircraft. The objects appeared suddenly at 80,000 feet, and then hurtled toward the sea, eventually stopping at 20,000 feet and hovering. Then they either dropped out of radar range or shot straight back up.

Then, Commander Fravor looked down to the sea. It was calm that day, but the waves were breaking over something that was just below the surface. Whatever it was, it was big enough to cause the sea to churn.

Hovering 50 feet above the churn was an aircraft of some kind — whitish — that was around 40 feet long and oval in shape. The craft was jumping around erratically, staying over the wave disturbance but not moving in any specific direction, Commander Fravor said. The disturbance looked like frothy waves and foam, as if the water were boiling.

The two fighter jets then conferred with the operations officer on the Princeton and were told to head to a rendezvous point 60 miles away, called the cap point, in aviation parlance.

They were en route and closing in when the Princeton radioed again. Radar had again picked up the strange aircraft.

“Sir, you won’t believe it,” the radio operator said, “but that thing is at your cap point.”

“We were at least 40 miles away, and in less than a minute this thing was already at our cap point,” Commander Fravor, who has since retired from the Navy, said in the interview.

By the time the two fighter jets arrived at the rendezvous point, the object had disappeared.

“I have no idea what I saw,” Commander Fravor replied to the pilot. “It had no plumes, wings or rotors and outran our F-18s.”

But, he added, “I want to fly one.”

According to The Black Vault, the videos may have been improperly released by a former Pentagon employee who had applied for permission to share them across several government agencies as part of a database on unmanned aerial vehicles (UAV) he was allegedly compiling. The man received permission to share the videos for "[US Government] Use Only," paperwork obtained by The Black Vault shows. However, Navy officials never declassified the footage for public release, Gradisher said.
