Ryan Graves was in the Navy for more than 10 years. He's since left the service. This summer, he testified before the House Subcommittee on National Security, the Border and Foreign Affairs. And he told the representatives that as a pilot and a formally trained engineer, he'd witnessed many phenomena that he could not explain. During a training mission in Warning Area Whiskey 72, 10 miles off the coast of Virginia Beach, two F-18 Super Hornets were split by a UAP," [said Graves]. "The object, described as a dark gray or black cube inside of a clear sphere, came within 50 feet of the lead aircraft and was estimated to be 5 to 15 feet in diameter. The mission commander terminated the flight immediately and returned to base. Our squadron submitted a safety report, but there was no official acknowledgement of the incident and no further mechanism to report the sightings. Soon, these encounters became so frequent that aircrew would discuss the risk of UAP as part of their regular preflight briefs." Graves now runs an organization called Americans for Safe Aerospace. It's a non-profit dedicated to understanding unidentified anomalous phenomena as a national security threat. He says he still doesn't know what he saw in the skies. Part of the reason for that is that any unidentified aerial phenomenon, as the government now calls them, is automatically highly classified. But he says, whatever they are, they must be taken seriously.
