"What the **** is that thing?" one pilot can be heard saying in the video.
The organization notes that the object has no wings or tail, and leaves no exhaust plume.
"Reports from different services and agencies remain largely ignored and unevaluated inside their respective bureaucratic stovepipes".
In a Washington Post op-ed, Mellon, who now works at The Stars Academy of Arts and Science (TTSA), says some US pilots have encountered a UFO and several have even caught footage of the occurrence, but not enough has been done about it.
Elizondo said he did not believe the object was necessarily "a little green space alien", but that they couldn't rule anything out, and that even if the object is simply a foreign aircraft, that alone should be alarming. The United States possesses nothing capable of such feats.

However, he wrote that sightings of odd and mysterious objects are not new to officials in the defense department and intelligence agencies but "nobody wants to be 'the alien guy in the national security bureaucracy; nobody wants to be ridiculed or sidelined for drawing attention to the issue".
"Nobody wants to be ridiculed or sidelined for drawing attention to the issue". Chris Mellon, an adviser to TTSA and a former deputy assistant secretary of defense for intelligence for the Clinton and George W. Bush administrations wrote an op-ed in the Washington Post on Friday arguing that more attention needs to be directed to the issue, or the USA risks being "technologically leap-frogged by Russian Federation or China".
As a result, he claims, the military does virtually nothing with the numerous reports of UFOs that servicemen make.
"There is no Pentagon process for synthesising all the observations the military is making".
"What we lack above all is recognition that this issue warrants a serious collection and analysis effort".
"I was honoured to serve at the DoD [Department of Defense] and took my mission of exploring unexplained aerial phenomena quite seriously", Elizondo said.
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.
This comes two months after the New York Timesposted an exposé on the Pentagon's mysterious UFO program, detailing just how much spend went behind a research that was mostly swept under the rug.
