An American pilot made a shocking claim he pursued an alien spacecraft and then he warned all the world leaders to pay more attention to the UFO sightings.

Recently, the former US government officer Luis Elizondo, admitted the Pentagon ran a real UFO sightings research, named the Advanced Aviation Threat Identification program.

Furthermore, he said this program was funded with extraordinary $22 million from the Congress.

The retired US Navy Pilot, David Fravor, spoke out to back up the claims of Elizondo.

Elizondo made the discharge of some classified videos from the US Defense Department of UFO sightings. One of those sightings, namely, was the craft Fravor saw running at an unbelievable speed.

The 53-year-old US Navy pilot was leading one of the two fighter jets on his routine training mission.

He was around 100 miles into the Pacific Ocean when he was called to inspect an aircraft detected on radar from their navy cruiser the USS Princeton.

The operator said that until that moment, they have detected many aircrafts, but never had a jet disposed to go and check it at that moment.

The craft first showed up around 80,000 ft before rushing into the direction of the ocean. It finally stopped around 20,000 ft and flew around before disappearing.

When Commander Fravor arrived at the destination, he noticed a white craft, floating 50 feet over the ocean.

He said: “It was just moving randomly around – this 40-foot long white tic tac looking thing, with no wings.

“It was a clear day with a blue background and it was perfectly white. We didn’t see any windows, no form of propulsion, nothing, just a big white object.

“It was rounded on both ends and had a cylindrical body which rounded in, the same front to back.

“I couldn’t tell what it was made of, it was bright white but it wasn’t reflecting a bunch of light.”

Fravor said he literally chased the aircraft, trying to get closer to it. Instead, the craft quickly hastened its speed and vanished in a few seconds.

According to him, what he witnessed was very strange. Moreover, he reported that he hasn’t seen anything similar hovering and climbing with that speed rate during his whole career.

“I was more curious than afraid. I wanted to see how close I could get to it, to see what it was,” he said.

The two fighter jets were ordered to go to a point 60 miles away.

However, the operator on the Princeton then said the mysterious UFO had turned up before them.

At this instant, they sent another aircraft to examine and record a radar footage. The minute and a half video depict an oval object flying before disappearing with an unusual speed.

Fravor said: “It jammed the radar, you couldn’t lock it with a conventional radar, you could passively track it and see it, but if you tried to grab a lock it wouldn’t allow you to do that.

“When it takes off and goes to the side that’s a significant amount of distance to travel in a very short period of time, we’re talking miles, that thing just goes poof and in about a second it’s off the side of the screen.”

Usually, planes always have a place where the exhaust is coming out. If you observe the video, there is no exhaust flume nor an indication of how the craft is moving around.

He believes this is one of the UFO sightings that definitely has an alien origin.

The only fact the craft flew with an incredible speed and performance was enough for the pilot to think it was an otherworldly act.

“I honestly don’t think humans have that technology to do what that thing did. Nor could the human body withstand accelerations like that. It’s an incredible technology to be able to go up to space, and back down and hang over the water,” said Fravor.

The US Navy pilot has now called the space expert Stephen Hawking to inspect the video and give his opinion.

He made a strict notice to all the world leaders that UFO sightings need to be taken seriously. Mentioning our ignorance towards the UFO’s intent, he warned the governments to pay more attention.
