Ex-Navy aviator claims he has seen hundreds of UFOs, says they are a threat to security

The interview is set to air on Sunday to the public.

According to Fox News, Graves said during the interview that he is concerned that these sightings are not taken seriously enough:

"I am worried, frankly. You know, if these were tactical jets from another country that were hanging out up there, it would be a massive issue. But because it looks slightly different, we’re not willing to actually look at the problem in the face. We’re happy to just ignore the fact that these are out there, watching us every day."

Graves was shown a video by host Bill Whitaker and asked to comment on it. He responded:

"This is a difficult one to explain. You have rotation, you have high altitudes. You have propulsion, right? I don’t know. I don’t know what it is, frankly. I would say, you know, the highest probability is it’s a threat observation program."

Luis Elizondo, a former official working for the Department of Defense, echoed Graves's sentiments:

"Imagine a technology that can do 600 to 700 G-forces, that can fly 13,000 miles an hour, that, that can evade radar and can fly through air and water and possibly space, and oh, by the way, has no obvious signs of propulsion, no wings, no control surfaces and yet still can defy the natural effects of Earth’s gravity. That’s precisely what we’re seeing."
