A former US Navy pilot urged government agencies to look into UFO sightings over the United States or face a “national security” threat. 

In an interview with Fox Digital, Ryan Graves, a former naval lieutenant who formerly piloted F/A-18 and has testified to having seen UFOs, opened up about his personal encounters with them. 

Graves served in the Navy for almost 11 years, flying the cutting-edge fighter jet and serving as a flight instructor. 

According to Graves, during his time in the Navy, he and other squadron members encountered an experience that has persisted to this day but was initially unidentified. 

He explained that these unidentified objects first appeared as contacts on their radar and camera systems before becoming visible to the human eye.

He recounted an incident when two aircraft from his squadron flew side by side, and one of these unidentified objects flew directly between them. According to Graves, a team member characterized the object as a “dark gray or black cube inside of a clear sphere.” 

Graves, the founder of Americans for Safe Aerospace, noted that although these objects occasionally remained stationary in an odd manner, they did not act like “tethered balloons.”

Graves explained this happened because these objects can move at high-speed rates. 

He explained that ultimately one would observe these things moving at speeds of around 0.6 to 0.8 Mach or about 250 to 350 knots at such altitudes and that they would either be in some holding pattern or appear to be moving just in one direction.
